Specification Range 11th Edition - Vent-Axia - 2017

Specification Range 11th Edition The UK’s Leading Ventilation Company www.vent-axia.com

A warm welcome to the latest edition of the Vent-Axia Specification Range catalogue.As part of the ongoing drive for energy efficiency within Europe, ventilation devices over 30 Watts come under the scope of the Energy Related Products Directive that came into force on 1st January 2016. The legislation sets minimum performance criteria across a range of fans and ventilation devices under two sets of legislation; ‘residential’ ventilation and ‘non-residential’ ventilation. As a result of the legislation we have reviewed our products and where required made updates to ensure they comply. In line with Vent-Axia’s drive to provide the best solution for our customer, we have taken the opportunity to update and improve some products at the same time as bringing the products in-line with ErP regulations. We have also improved the way we supply some of them - giving you more choice and flexibility over how you stock and sell the products. This edition of our Specification Range catalogue shows the continued investment we are making in our products and services to improve and add to our already comprehensive range. In this catalogue, we have bought together our Lo-Carbon residential and our non-residential products in one place providing what we believe to be the best solutions for a wide range of specification today. We have introduced many new models which expand upon our traditional, well-proven products as well as broadening our capabilities further with a whole host of innovations in Vent-Axia Lo-Carbon and energy reducing ventilation solutions. For example, the EKF kitchen fan has a built in EC motor speed control, high temperature rating of up to 120 degrees, motor out of the airstream and specific fan powers of below 1 W/l/s; we believe there is no better solution available.We thank you for your continued custom and feedback, and are always willing to answer any questions you may have.

Legislation Approved Document F 2010 - Means of Ventilation The purpose of this regulation is to ensure adequate means of ventilation is provided for people in the building. According to the document, ventilation is the ‘removal of stale air from a building and replacement with freshoutside air.’ By providing fresh outside air to breath, ventilation assists in the dilution and removal of pollutants as well as a reduction in humidity/condensation, which combined create a more pleasant environment and relief for asthma and allergy sufferers. Part F is a performance based whole building solution stating not only what should be achieved, but also guidance on how this can be achieved. The pollutants in today’s modern dwellings has lead to these changes, with the types of pollutant and the acceptable levels now detailed in the Approved Document Part F 2010. Nitrogen Dioxide (NO 2 ) Carbon Monoxide (CO 2 ) Total volatile compounds (TVOC) Bio-effluents (body odours) Within ADF 2010, Ventilation requirements for new build properties reference the whole dwelling based on an analysis of floor area, number of bedrooms and occupants. There are four systems covered in ADF 2010 including Intermittent Extract Fans, Passive Stack, Continuous Mechanical Extract Ventilation (MEV) and Mechanical Ventilation with Heat Recovery (MVHR). A guide called the ‘Domestic Ventilation Compliance Guide’ is available. This covers installation practices as well as sign off and commissioning.Efficiency regulations require buildings to be better sealed and more airtight. In ADF 2010 there are two ventilation rates based on the deign infiltration rate of your building. There is one rate for properties with infiltration rates over 5m 3 h/m 2(leakier properties) and a higherventilation rate for properties below 5m 3 h/m 2(tighter properties).Thepractical outcome of this means that in airtight properties, the following applies: •Trickle vents with intermittent fans are up to 50% bigger •MVHR rates are increased With MEV in properties at 5m 3 h/m 2or over no trickle vents are needed. Guidance is available for ventilation of basements in houses and trickle ventilation for replacement windows. Compliance with Part F requires installed performance to meet the ventilation rates quoted in the Document. This means that ventilation has to be commissioned and signed off by a competent person. Noise With increasing airtightness the acoustic properties also improve leading to a reduction in external noise entering our dwellings. However this makes any noise generated inside the property even more noticeable, so in Part F a maximumnoise level of 35dB(A) has been set for the trickle speed on continuous ventilation systems. Approved Document L 2013 – Conservation of Fuel and Power These documents set minimum performance levels for ventilation efficiencies and reducing the consumption of the systems. These regulations have brought some significant changes to the ventilation sector in a bid to improve both air quality and energy efficiency. Part L – Overview •Target emission rates, along with fabric energy efficiencystandards areaimed at reducing the carbon emissions by 6%•Non-domestic building services compliance guide shows specific fan power requirements. Heat recovery efficiency minimums to EN308 test standard •Specific fan power (SFP) targets of 1 W/l/s for new orreplacement commercial kitchen extract systems •Minimum energy efficiency level for all ventilation systems. New build and refurbishment applications for intermittent fans must have an SFP of less than 0.5 W/l/s.

4 As part of the ongoing drive for energy efficiency within Europe, as of January 2016 ventilation devices over 30 Watts now come under the scope of the Energy Related Products Directive. The legislation sets minimum performance criteria across a range of fans and ventilation devices under two sets of legislation; ‘residential’ ventilation and‘non-residential’ ventilation. As a result of the legislation we have reviewed our products and where required made updates to ensure they comply. The primary changes have meant that a number of products have had alternative motors specified or have been updated to enable speed control. However, we have ensured that the installation methods remain unaffected. Through the review we have also taken the opportunity to rationalise our range where needed. All relevant products in this literature have been updated as required by the ErP legislation. Please note that where a product changes due to ErP, there will be a transitional period as we move from the old to the new model, and any stock you currently hold will not be affected by this regulation and can be sold as normal. Residential Products Residential Products has a secondary directive which requires some products to carry an energy label as described below: Residential Ranges – Small fans The majority of small residential fans are unaffected by the legislation as any device below 30 Watts is currently out of scope.The information on them is recorded however and can be found atwww.vent-axia.com/erpThe Duet and Gemini fans have been delisted, but are still available as spares so please contact sales@vent-axia for more information. MVHR and MEV products These products do come into the scope of the legislation and will carry an energy label. There are some minimum energy efficiency requirements as well as the requirement for a summer bypass on heat recovery models. A small number of our products have been updated to ensure they meet these requirements. The following product has been discontinued: •Kinetic E Energy Efficiency Class Products within the scope of ErP now need to carry a rating that shows their Energy Efficiency Class. This information is called a ‘SEC Class’ and is provided in all product literature and on the energy label. A product’s SEC class is affected by how the product is controlled. This is referred to as Local Demand Control (LDC) and indicates how many ‘sensors’ a fan should have. The regulations require that single room fans, such as a bathroom fan, should have at least 1 sensor. Units that are ducted, such as an MEV unit, need to have more than one sensor. Examples of these are a pull cord/light switch or humidistat. In our literature, where appropriate we have shown the rating if an additional LDC was added to a product. In those cases, you will see a table similar to the one below which has a heading (incl LDC). This is so you can choose the most efficient option for your needs.

5 Non-Residential Ranges Non-Residential products have had minimum performance and efficiency levels established, but there is no requirement to introduce energy labels. Some products have been updated with new motors and enabled for speed control. Non-Residential ranges are split into a number of different categories dependent on their application and function. These can be describedas follows: 1. Fans 2. Uni-directional Ventilation Units 3. Bi-directional Ventilation Units 1. Fans These are products where there is a simple single case that directs air on and off the impellor. Examples include axial plate and case fans. These examples are out of scope of the legislation.Changes to the way we sell products The ErP regulations gave us the opportunity to review our product ranges and in some cases has enabled us to improve the way we stock and sell them. Examples of this include T-Series and Standard Range fans. You can now buy these as either the entire product or in modular format. The entire product can be purchased using the existing part number that you have always used. Alternatively, you can purchase just the motor core or just the fitting kit as required. If you are unsure of the new part number don’t worry, as we will be able to tell you what the new one is.In some instances however you may receive more than one box.

6 2. Unidirectional ventilation units This includes products that are one direction only, and where thereis a secondary housing around a fan. This is the product category which has required the most changes.The impact of the efficiency legislation has meant that it has become virtually impossible to comply using a forward curved AC centrifugal fan. We have therefore moved to backward curved centrifugal fans in all of our AC box fan ranges. This has meant changes to the box sizes and adjustment to performances across the range. The product ranges have therefore been updated: ACQ/ATQQP/QPTWWe have a number of product ranges that have been reaching the end of their life cycle and we have taken the opportunity to rationalise these and where possible provide a suitable alternative range. The following product ranges are no longer available: VMD RMV GRB GDB GRD Other product ranges have been rationalised to provide one solution, these include: ARH – rationalised to MFQ RBH – rationalised to RMH 3. Bi-directional ventilation unitsThese are product ranges that both supply and extract such as heat recovery. There are now minimum energy requirements set for heat recovery efficiency.Any product with an efficiency of 67% or lower does not comply. Both the Totus 2and ERV-HIBOX ranges are unaffected by thesechanges, however the low efficiency heat recovery ERV-BOX products have been discontinued. Heat recovery minimum efficiency 67% 67% Energy Related Products Directive (ErP)

7 Things have moved on a bit since 1992 when ventilation was first introduced into the Building Regulations. Here is an overview of the changes from 2006.2006 – Part F included continuous ventilation for the first time.Ventilation systems were being installed by skilled persons but the performance data was never tested. Part L changes meant that SAP Q products could be included as part of the dwelling’s SAP calculations. 2010 – Design, install and ensure its used correctly. With dwellings being designed with increased energy efficiency and reduced air permeability, ventilation systems now require specific flow rates and there is more demand for highly efficient heat recovery to help reduce the DER’s. Ventilation is now required to be installed correctly with the installation recorded and measured plus there needs to be guidance to the home occupier as to how it operates. 2013 – New Part L requirements meant a reduction in air leakage and increased air tightness.These trends continue to drive the adoption of higher efficiencies and the importance of installation increases as the advantageous air from leakage is reducing further.2016 –With the commitments made in the recent COP21 meeting and the Paris climate agreement, focus on decarbonisation and energy efficiency is set to continue. The Energy Performance of Buildings directive and the Energy related Product Directive are having an impact on the performance and efficiency standards of ventilation. These drivers will continue to develop and are expected to transform into standards in the future meaning an even greater focus on energy efficiency. The commitment to zero carbon buildings in 2019 will mean revisions to Part F and L of the building regulations are likely. As we focus our efforts to drive down the energy that we use in buildings, the risk of airtight, well insulated buildings being the potential cause of respiratory problems increase. Therefore the importance of well-designed and well installed systems that perform as designed increases. This will lead to increased focus on competence when installing ventilation and is likely to drive advances in the way installers are trained. Things to Remember •Airflow performance •Minimum energy efficiency limits •Good installation •Use by occupiers Future Direction

14 The UKs first App controlled unitary fan The launch of Svara marks the next generation of unitary fans.For electricians, installation is made simple through Svara’s Bluetooth-enabled App allowing you to choose whether to opt for intermittent or continuous ventilation; whether you would like the humidistat to trigger operation or not; and whether the overrun timer is required. No more fiddly switches and jumpers!For consumers Svara offers improved comfort in their homes since it has been developed to allow households to take control of their indoor air quality via the App. Aesthetics and silence The name Svara takes its influence from the fan’s Swedish heritage – a country well known for iconic and well thought out designs.Consumers willbe attracted to Svara’s good looks with its sleek modern design, plus with noise a key issue for consumers, households will also be impressed by Svara’s quiet running, operating at just 17 dBA on low trickle. It is also easy to clean as the central module disconnects the motor from the rest of the fan allowing it to be simply wiped with a soft cloth, and at only 4W the energy efficient Svara also boasts low power consumption. One model fits allVent-Axia Svara is programmed to cope with the vast majority of installations.The fan is set as default to work continuously at a trickle flow of 10l/s. When the fan senses a somebody in the room it increases the flow to 19l/s. If the humidity rises rapidly, for example when the shower is on, the fan goes up to maximum flow at 30l/s. When the fan senses the humidity level has returned to normal it reverts to the trickle flow of 10l/s. If other settings or functions are desired, they can be selected through the Vent-Axia Connect App which can be downloaded from the App Store and Google Play. FunctionsLight sensorWhen the light sensor is enabled Svara senses when someone is in the room and then activates.Its sophisticated light sensor is triggered by light movement and shadows. It is possible to set a delay-on so the fan is not triggered by the light during quick night time bathroom visits. The light sensor can also distinguish between headlight flashes from cars and room occupancy, so it is not triggered by passing cars, avoiding nuisance running. The sensitivity of the light sensor can be adjusted via the App. Overrun TimerThe light sensor provides an overrun timer but only requires a live and neutral. In houses where there isonly a basic fan installed, the home owner can upgrade to a timer fan without having to rewire.HumidistatSvara features a humidistat which reacts to sharp changes in humidity, for instance when someone is taking a shower. When set to continuous running, once the humidity sensor is activated the fan runs at 30l/s until humidity returns to normal levels then the fan powers down to 10l/s. Ambient humidity changes will not trigger the humidistat. It is possible to change the sensitivity of the humidity sensorvia the App.Silent scheduling and Automatic cyclesThe silent hours scheduling function allows you to deactivate the boost function on the Svara via the App, for example, this would prevent nuisance noise over night. Additionally during a vacation you can set Svara to an airing mode which operates a purge function every 12 hours for either 30, 60 or 90 minutes depending on selection. However, Svara’s sophisticated controls, will not purge if the light sensor detects that there is someone in the house.

The result is a stylish fan with a surface depth that appeals to the eye and that matches modern fittings found in today’s bathrooms. The visible blades give a retro-feel and helps to give the fan a very quiet noise level. Silent Operation The open impellor and the unique method of operating the motor enables a greater array of operating options including silent continuous ventilation along with adaptable speed control and flexible timer functions.Humidity Control The iQ features an intelligent, fully automatic humidity sensor for moisture control. This means the fan learns to run only when it can make a difference to the indoor air quality. The fan continually monitors and records the moisture content to allow it to map the humidity profile throughout the year. This process enables the fan to ensure that it runs only when the fan can lower the moisture content in the air. This reduces nuisance running. The fan also has two modes for moisture control, silent or boost mode which can be selected via the touch pad control. Control Panel Our aim has been for the end user to be able to control and understand the basic fan functions, without the need of reading the manual. When the fan is connected to the power supply, it also performs a self-test where all the status lamps on the control panel are tested, as well as the function of the motor. Ideal for those installing to ensure that everything works. The simple controls, along with the LED feedback make the commissioning and any readjustment, quick and easy to complete. LED Feedback With many fans it is difficult to understand the exact mode that they are running in. We have now simplified this to provide a visual indicator to see what the fan is doing and which mode is currently active. The fan uses three different colours on the visible status lamp to communicate exactly what it is doing. A blue light signifies that the fan is working to evacuate moisture via the humidity sensor. A yellow light signifies that the timer is running. And a purple light signifies that the fully automatic airing function is active. You Choose How The Fan Works The intelligent overrun timer can be operated in several different ways, either via the light switch, integral pull-cord or a separate switch either as a standard On/Off or as a momentary switch stopping automatically after the overrun on time. You use the control panel to easily set the required post-running time at 15 or 30 minutes, depending on your choice. Full Surface Mounted Installation With the impellor and motor assembly designed to be low profile and accessible for maintenance, spigots on the fan are completely removable. This design enables the fan to be mounted onto a wall without any spigot so that it can be truly surface mounted. This is an ideal function if you have a duct with a smaller dimension than 100 mm or a duct that bends directly off of the back of the fan not providing any depth in the wall for the spigot. Cleaning and Maintenance For a fan to ventilate effectively, it is vital that it is kept clean and that the ductwork and grilles are free from dust that can reduce the air flowing through them. This is the first fan to be introduced with the ability to simply remove the impellor and open the centre of the fan to gain free access to the duct. Using the ‘swing-out’ function you can easily clean and clear the fan e.g. a clogged grille on the outside of the façade. Click the button to remove the impellor, then press the snap in catch and swing out the motor - that’s it!

17 Automatic Airing Function The airing function means when the fan has been inactive for 26 hours, it runs an airing programme for 60 minutes to exchange the air in the bathroom. No more worries about stuffy, musty odours in the bathroom when returning from holiday. Lo-Carbon 5 Year Guarantee As there is an integrated power adapter in the fan we have been able to use a low voltage motor that has a life span of approximately 60,000 hours. This is about 3-5 times longer than a standard fan. The motor features extremely quiet bearings. By using a low voltage motor we can significantly limit power consumption. The fan only consumes 5 Watts, about a third of a conventional AC bathroom fan. Models Lo-Carbon iQ Multi control fan with option to run on intermittent or continuous setting.

Building Regulations Approved Document F gives examples of four main methods of ventilation. System 3, Continuous mechanical extract ventilation, can be achieved using a single centralised extract unit such as the Sentinel Multivent ducted to ‘wet’ rooms (kitchen, bathroom, en-suite and WC) or by decentralised individual fans, such as the Lo-Carbon Centra in the ‘wet’ rooms. The fans run continuously at near silent levels providing a simple and effective form of ventilation. SELV (Safety Extra Low Voltage) is designed for areas where a fan can be installed within Zone 1 in a room where there is a fixed bath or shower. Ingress Protected (IP) to IPX7 Lo-Carbon Centra SELV can be fitted safely within the spray area. The separate transformer can be mounted away from the spray zone and out of reach from the bathor shower. The Lo-Carbon Centra meets the latest requirements of the Building Regulations Approved Document F for wholehouse system ventilation and all models come with a 5 year motor guarantee. Selection of the two trickle flow rates (6l/s or 9l/s) is via a simple ‘jumper’ on the control board. Different methods are available for operating the 15 l/s boost speed from a simple switched live to integral humidistat. See individual models for further details. The attractive and discreet styling of the Vent-Axia Lo-Carbon Centra will complement the décor of any new home while virtually silent operation ensures optimum ventilation is achieved without intrusive noise.

dMEV, MEV & PIV Systems What is dMEV & MEV?The current Building Regulations Approved Document F gives examples of four main methods of ventilation. System 3, continuous mechanical extract ventilation, can be achieved using a single centralised extract unit such as the Sentinel Multivent ducted from ‘wet’ rooms (kitchen, bathroom, en-suite and WC) or by decentralised individual fans (dMEV) in the ‘wet’ rooms. The fans run continuously at near silent levels providing a simple and effective form of ventilation. Lo-Carbon ResponseThe continuous running, constant volume Lo-Carbon Response dMEV unit features an innovative digital display. The unique display (patent pending) provides the calibrated installed airflow and pressure of the installation meaning that there is no need to test the installation with an airflow measuring device. Quiet running and with high pressure development, the Response is best in class - an achievement that was recognised when it won Product of the Year at the prestigious Housebuilder Awards 2014.

Building Regulations Approved Document F gives examples of four main methods of ventilation. System 3, Continuous mechanical extract ventilation, can be achieved using a single centralised extract unit such as the Sentinel Multivent ducted to ‘wet’ rooms (kitchen, bathroom, en-suite and WC) or by decentralised individual fans, such as the Lo-Carbon Centra in the ‘wet’ rooms. The fans run continuously at near silent levels providing a simple and effective form of ventilation. SELV (Safety Extra Low Voltage) is designed for areas where a fan can be installed within Zone 1 in a room where there is a fixed bath or shower. Ingress Protected (IP) to IPX7 Lo-Carbon Centra SELV can be fitted safely within the spray area. The separate transformer can be mounted away from the spray zone and out of reach from the bathor shower. The Lo-Carbon Centra meets the latest requirements of the Building Regulations Approved Document F for wholehouse system ventilation and all models come with a 5 year motor guarantee. Selection of the two trickle flow rates (6l/s or 9l/s) is via a simple ‘jumper’ on the control board. Different methods are available for operating the 15 l/s boost speed from a simple switched live to integral humidistat. See individual models for further details. The attractive and discreet styling of the Vent-Axia Lo-Carbon Centra will complement the décor of any new home while virtually silent operation ensures optimum ventilation is achieved without intrusive noise.

Quiet running and with high pressure development, the Response is best in class.The Response Fan from Vent-Axia Following the introduction of the Domestic Ventilation Compliance Guide within Part F 2010, and the requirement to test the installed airflow of extract fans, the Response fan from Vent-Axia provides the easiest install available. The unique display (patent pending) provides the calibrated installed airflow and pressure of the installation meaning that there is no need to test the installation with an airflow measuring device. The constant volume technology automatically adjusts the speed of the fan to ensure the desired airflow is delivered. With a new silent higher pressure axial impeller Lo-Carbon Response can meet the requirements of many domestic installations without the need to use a traditional centrifugal fan.Axial, rather than centrifugal? Some centrifugal fans can develop pressure but the actual installed airflows can mean that the pressure is of no use as the airflow falls below the requirement. Using the new high pressure silent axial impeller has enabled the fan to not only develop great installed performance over duct runs, but to do it in the most energy efficient way. Response can provide excellent pressure whilst still maintaining energy efficiency and not wasting energy on high pressure at low air volumes. This enables the fan to save up to 64% of the specific fanpower (SFP) of the SAP PCDB data for existing centrifugal alternatives.

A loft mounted positive input fan draws fresh air from the insulated loft, filters it and gently feeds it into the dwelling via a ceiling mounted diffuser. Stale air in the property is forced out through the natural forms of ventilation, such as window mounted trickle vents. Installation The Lo-Carbon PoziDry can be installed in a loft space and can be suspended from a roof beam or be floor mounted, with a purpose-designed diffuser normally located over the stairwell of a conventionaltwo storey dwelling or in the main hall of a bungalow.The Lo-Carbon PoziDry is set to the appropriate speed at installation based on the size of the dwelling, providing positive pressure input ventilation. Background ventilation openings provide the exhaust points. Performance The robust construction of the Lo-Carbon PoziDry features a specially developed Lo-Carbon DC fan/motor arrangement which runs quietly and delivers incredibly low running costs. The Lo-Carbon PoziDry uses a sensor to monitor the temperature in the loft, automatically adjusting the air volume when necessary. ‘Trickle’ speed is automatically selected when the ambient loft temperature is up to 18°C. ‘Normal’ is automatically selected when the ambient loft temperature is between 18 and 27°C providing partial heat recovery. If the ambient loft temperature exceeds 27°C, the Lo-Carbon PoziDry will automatically switch to standby (no airflow). The standby power consumption is 2W.In the case of the integral 500W heater version, the heater element is automatically activated when necessary and tempers the supply air to 10°C. Can be used for air replacement in conjunction with an extract fan. Filter The unit includes a G4 filter with up to 5 years maintenance intervals to reduce the number of call outs needed throughout it’s life span. Day logger As standard. Measures the number of days the product has been switched on to provide precise running information. Speed Control With selection of 2 of 6 speeds available up to 50l/s, the unit is suitable for houses up to 360m 3 .Heater An optional comfort heater is available for operation when the incoming air temperature becomes low.Air Replacement Grille Set For air replacement through doors. Consists of a two-piece telescopic set, which fits unobtrusively on either side of the door panel. Minimum fixing thickness 30mm. Plastic. Dimensions: 454 x 90mm. Typical Specification The unit should be mounted in the loft space with a diffuser in self-extinguishing ABS positioned at the top of the stairwell. The unit meets the EMC and low voltage directives.

The unit is duct mounted and can be fitted in a number of locations within a single floor flat or apartment.Air is drawn into the Lo-Carbon PoziDry Compact unit via an external inlet and through a short length of duct. The specially developed fan/motor assembly (using the Lo-Carbon DC motor technology) draws the air through an integral, high capacity, washable filter. The backward curved impeller guarantees increased efficiency, lower sound levels and better performance. The fresh, filtered airflow passes along the ducting and terminates on an internal wall with a discreet grille. This directs the airflow upwards where the incoming air mixes with the warm air that gathers at ceiling height. The system provides fresh, tempered air into the home and creates an indoor environment where the damaging effects of condensation find it hard to exist, benefiting both the occupants and the structure of the building.The Lo-Carbon PoziDry Compact can be used for air replacement in conjunction with an extractor fan. A G4 filter is included as standard.Performance The Lo-Carbon PoziDry Compact uses a sensor to monitor the ambient temperature, automatically adjusting the air volume when necessary and providing partial heat recovery.‘Trickle’ speed is automatically selected when the ambient temperature is up to 18°C.‘Normal’ is automatically selected when the ambient temperature is between 18 and 27°C.If the ambient temperature exceeds 27°C, theLo-Carbon PoziDry Compact will automatically switch to standby (no airflow).

Sentinel Control The Sentinel controller is the most advanced system available, providing Demand Control Ventilation (DCV), minimising energy consumption and noise levels, and optimising ventilation performance. Sentinel controlled units may be set to operate fully automatically or with varying levels of manual intervention. Building Management System (BMS) OptionsThere are two levels of BMS available: Basic Output and full Electronic BMS. Basic Output provides a 5 volt output from the LED terminals on the controller. This output occurs whenever a message appears in the digital display, for example; ‘Check Filters’ or a fault code. The output can also be converted to volt-free with the addition of an optional Opto-Coupler. Electronic BMS: A full range of two-way digital signals are available through the RJ11 connector on the control board. The BMS system provider will translate this signal to extract the desired data. ContactVent-Axia to discuss your specific requirements.LEDAlarmMVHR units are often installed in lofts or other locations where they are difficult to monitor. The optional remote LED alarm illuminates when any message is visible in the MVHR unit display panel. The LED alarm can be installed in a convenient location within the dwelling allowing end users to see that the unit requires attention. Control Inputs Five volt-free pairs of switch terminals for sensor inputs allow boosting from a full range of Vent-Axia controllers – humidistats, PIR, timers. Two terminals with 0-24V outputs allow 0V to 10V proportional control by sophisticated controllers such as CO 2sensors and proportionalhumidistats.

69 The optional Ventwise controller senses temperature rise in a bath/shower hot water supply and/or current in a cooker/hob electrical circuit to activate boost, ensuring additional ventilation when needed. Switched-live for boosting via light switches (220-240 V AC) or manual Normal/Boost switches. This connection has the advantage of Delay-On and Delay-Off facility. Delay-On enables you to prevent the Boost airflow between 0 and 10 minutes, after a light switch has been activated. Delay-Off allows the Boost airflow to continue after a light switch is turned off to ensure effective clearance of humidity. This timer is adjustable between 0 and 25 minutes. The units can be boosted incrementally via the on-board controller or the Wired Remote Controller: One press = 30 minutes, two presses = 60 minutes, three presses = continuous.

Purge will continue for two hours unless cancelled by pressing the Boost button again. Summer BypassAn internal damper operates when the external temperature is below the internal temperature, and the internal temperature is too high. The bypass opens and allows the cooler outside air to help cool the dwelling. Normal mode: Fans run on Normal speed with bypass open until the internal dwelling temperature falls below the set 'Indoor' (maximum desired) temperature.Evening Purge mode: The fans run on Boost speed until the internal temperature falls below the set 'Indoor' temperature. If, after five hoursthe internal temperature is still above the set 'Indoor' temperature, the unit will switch down to normal speed for the remainder of the 'bypassopen' period. Night-time Purge mode: As Evening Purge, except that the unit will continue on Boost speed until the internal air temperature reaches the 'Outdoor' temperature set point (Default 14°C). This mode gives pre-cooling of the dwelling for the following day. In Evening and Night Time Purge modes, the user can turn off the boost function by pressing the Boost button. A Summer Bypass can make a contribution to reducing internal temperatures but is not a substitute for appropriate design and construction.Frost ProtectionIn order to prevent frost forming inside the unit in winter conditions, the Kinetic range employs a sophisticated frost protection strategy that modifies the airflows ensuring heat recovery continues down to -20°C. Below this temperature, the units will operate as 'extract only' fans. If balanced ventilation is required at low temperatures, a duct pre-heater should be used. System Cooker Hood Range System canopy hoods are a motorless hood with extract being provided by the MVHR unit. When the Boost button on the canopy is activated, the MVHR unit goes to boost setting and the summer bypass opens preventing cooking by-products entering the heat exchanger cell.

Two terminals with 0-24V outputs allow 0V to 10V proportional control by sophisticated controllers such as CO 2sensors and proportional humidistats. The optional Ventwise controller senses temperature rise in a bath/shower hot water supply and/or current in a cooker/hob electrical circuit to activate boost, ensuring additional ventilation when needed. Switch-live for boosting via light switches (220-240V AC) or manual Normal/Boost switches. This connection has the advantage of Delay-On and Delay-Off facility. Delay-On enables you to prevent the Boost airflow between 0 and 10 minutes after a light switch has been activated. Delay-Off allows the Boost airflow to continue after a light switch is turned off to ensure effective clearance of humidity. This timer is adjustable between 0 and 25 minutes. Summer BypassAn internal damper operates when the external temperature is below the internal temperature, and the internal temperature is too high. The bypass opens and allows the cooler outside air to help cool the dwelling.

If, after five hours the internal temperature is still above the set 'Indoor' temperature, the unit will switch down to normal speed for the remainder of the 'bypassopen' period. Night-time Purge mode: As Evening Purge, except that the unit will continue on Boost speed until the internal air temperature reaches the 'Outdoor' temperature set point (Default 14°C). This mode gives pre-cooling of the dwelling for thefollowing day. In Evening and Night Time Purge modes, the user can turn off the boost function by pressing theBoost button. Frost Protection In cold climates there is a possibility of frost building up on the intake side of the heat exchanger.

The Vent-Axia Pure Air combines particulate and gas filters to remove pollutants prior to entering residences and commercial buildings through mechanical ventilation and heat recovery systems. The Vent-Axia Pure Air is designed to bring outdoor air pollutant levels within the guideline exposure limits as set out in the World Health Organisation Air Quality Guidelines and the CAFE Directive prior to entering an occupied space. Indoor air quality (IAQ) is becoming increasingly important with properties being built in urban, industrialised areas. The Vent-Axia Pure Air offers a complete filtration solution with a range of specifiable products that meet planning obligations and refine traditional filtration, leaving home owners withconfidence in their heat recovery systems.What does it do? The Vent-Axia Pure Air sets the benchmark for high level filtration. It targets pollutants generated outside of the home, by traffic and industrial processes, and reduces these before supplying the air into the dwelling.The Vent-Axia Pure Air filter is fitted to the intake airflow and incorporates two types of filtration: •Enhanced activated Carbon which removes unpleasant odours and harmful gasses such as Nitrous Oxide (NO 2 ). •G4 or F7 particulate filters which can remove tiny airborne contaminants such as pollen, bacteria and even PM2.5 diesel particulates. The combination of MVHR and Vent-Axia Pure Air filtration offers the ideal indoor environment. Unit Specification The Vent-Axia Pure Air is manufactured from 1.2mm Galvanised Steel together with suitable sealing for particulate and gas filters. Access is available on both sides via bolted lift off panels. Various round and rectangular transformation spigots are available to suit ductwork systems for both domestic and commercial duct work.Filter Specification Particulates, PM10, PM2.5The Vent-Axia Pure Air can house up to two particulate filters. Panel filters of Grade G4 to EN779 having an arrestance above 90%, making it suitable for the removal of PM10 Particulates. An additional particulate filter of grade F7 to EN779 can be included to further reduce smaller particles (PM2.5) to an efficiency between 70% and 80% at 0.4 μ m. Pollutant Gases, NO 2 , SO 2 , O 3 , VOC The gas stage filters in the Vent-Axia Pure Air are designed to achieve a minimum contact time suitable for the removal of pollutant gases at the rated airflow. A specially formulated activated carbon and chemical mix acts upon pollutant concentrations common in dirty city air, reducing them below guidelines set by current legislation.

120 Arterial Duct System •Reduces installation time •Can be applied in SAP as a rigid duct system •Crush resistant semi-rigid duct •Unique low-resistance manifolds •Simple installation through joists •Smooth inner surface with antistatic and antibacterial coating •Combines the advantages of rigid ducting with the versatility ofa semi-rigid system Arterial System For use with MVHR systems, the Arterial air distribution system provides a flexible, highly robust solution, which can significantly reduce the installation time when compared to a standard system. Rigid vs Semi-Rigid Systems Both traditional duct types have limitations in modern construction. Rigid systems: Passing rigid duct through a floor cassette at right-angles to the joists is time consuming and multiple connections increase the risk of leaking ductwork.Semi-rigid Systems: It can often be difficult to accommodate two distribution boxes and multiple semi-rigid pipe runs in new buildings and the time saving advantages are soon overtaken by the additional cost of materials. Reduced Installation TimeThe Vent-Axia Arterial range combines the advantages of semi-rigid and traditional rigid ducting in one simple system. The system is independently tested and can be applied in SAP as a standard rigid system. Drops between floors to/from the MVHR unit remain in rigid PVC, having the advantage of low space usage and low cost. Traversing through joists in a floor cassette is much simpler and faster when using semi-rigid duct. The secret to the Arterial System is the unique low-resistance distribution plenum (Patent Pending) which is sited between joists allowing connection between semi-rigid and rigid sections.

125 Universal Roof Vents •Models available for both pitched and flat roof types •Complies with Building Regulations•Suitable for most installations •Corrosion and weather proof•Compatible with both mechanical and natural ventilation systems •Three colours available for pitched roof vents Wholehouse ventilation systems require termination to the external atmosphere, often through the roof. To ensure that the ventilation system is able to achieve it’s optimum level of performance, it is important that a suitable roof termination product is installed.With this in mind, Vent-Axia is pleased to offer a range of Universal Roof Vents; including products suitable for both pitched and flat roof types.A selection of colours and sizes should ensure that our range offers a product suitable for most residential applications with a pitched or flat roof.Models Universal Roof Vent suitable for Pitched RoofsManufactured in the UK, these products have been specifically developed for use with both natural and mechanical ventilation systems.All models have been independently tested by the BRE to BS476 Part 3: 2004 and have been awarded an AA classification - the highest possible. Thus they can be installed without restriction on any pitched roof. All models have low resistances to airflow (see table) and incorporate condensation grooves to prevent any condensate running back down the duct. Universal Roof Vents are designed to resist the ingress of deluge and driving rain. Universal Roof Vents (pitched roof models) are suitable for roof pitches between 20° and 60°.The pitched roof vents are available as a ‘tiled’ roof vent to fit alongside most traditional roof tiles, as well as a ‘slate’ version which can be easily cut down to fit alongside all traditional roof slates.

126 NEW Internal Fit Wall Kit •Ideal for high-rise applications •Suitable for 100mm fans •Quick & easy installation •Extendable length•Fits entirely from inside the property •Reduces water ingress •Includes low-resistance external grille •Suitable as a passive air grille •Covers external break-out Internal Fit Wall Kit The NEW Internal Fit Wall Kit is designed to simplify installation and improve the finish of 100mm through the wall installations, also providing an external grille and water ingress protection shroud. High Rise Buildings The Wall Kit is fully installed from inside the building, avoiding the need for scaffolding and significantly reducing the cost and complexity associated with these sites. After core-drilling a 117mm hole, or utilising an appropriate existing hole, the Kit simply pushes through from the inside of the building. Spring pins secure the external grille in position and the external shroud deploys around the grille covering up break-out from the external surface. Installer Friendly Quick and easy to install, the Internal Fit Wall Kit cuts down time on site when compared to traditional methods using flexi-duct. Installers no longer need to spend time fixing flexi-duct to fans and grilles using jubilee clips, or going outside to fit the grille. The tubes extend to accommodate wall thicknesses from 225mm up to 390mm and lock into position for a secure fit. The internal flange is also flexible enough to accommodate deviations in the internal surface finish. Building Regulations The external grille free area is greater than 90% of the area of the duct making it suitable for continuous running systems as well as for intermittent fans. Backdraught ShutterThe Internal Fit Wall Kit has optional backdraught shutter models. Particularly useful with intermittent fans, the backdraught shutter will ensure no draughts and gusts come in to the home through the wall kit.

152 Profile Our radiant heating product range gives the flexibility to deal with large and small unheated spaces which would be uneconomical to heat using traditional space heating.Areas such as bars, restaurants, terraces, delivery areas, warehouses and churches are some examples where our radiant heating products will provide an economical heating solution. Radiant heat and its advantages The heat we feel from the sun is called radiant heat and is part of the electromagnetic spectrum called infrared. Ultra violet and visible light also belong to the same family.Visible light is the easiest part of this spectrum to understand, light travels in a straight line from the source, is unaffected by air and is invisible until it hits a surface. Shadows are a good example of this and are the absence of light.Infrared rays behave in the same way, we cannot see them but we can feel them as warmth. A good example of this is the effect created when you move from the shade into the sun, although the temperature is the same, the perceived temperature when in direct sunlight is much higher. This phenomenon makes sunbathing possible during winter holidays.There are three categories of infrared; short wave (IR A), medium wave (IR B) and long wave (IR C), the shorter the wave length the easier it travels through the air. The advantage when using short wave infrared heating is that the rays cut through the air and are not affected by air movement and only transmits its energy when it collides with a solid object. The rays also travel in a straight line so can be directed where you need it, ideal in locations which feature high ceilings, have high air change rates orare outside.

209 Air Quality Sensor Automatically reacts to the depletion of air quality, sensing unpleasant smells and toilet odours to regulate mechanically ventilated areas such as cinemas, pubs, clubs, restaurants, kitchens, toilets and conference rooms. This is not a CO 2sensor. The sensor switches the fan On when the air quality declines below an adjustable preset level. This is registered by the ceramic sensing head which is self-cleaning, a process which occurs every time the unit is triggered.When the atmosphere has returned to normal, the fan will continue to run for a pre-set period (adjustable between 1-25 minutes) and then switch Off. The air quality sensor should not be used for the detection of combustible gases and is not designed for use as a smoke detector in an alarm system.For use with various Vent-Axia fans within maximum rating below.

Construction Vent-Axia Sabre ®Plate Mounted Sickle fans are based on an integratedimpeller and external rotor motor design, which produces a very compact unit. Together with a specially designed bell mouth inlet and mounting plate, the complete fan is lightweight and ensures an excellent performance to sound level ratio. The mounting plate is formed from a single sheet, protected with a tough epoxy paint finish. Inlet finger guards and motor supports are manufactured from steel rod and electro welded for extra strength. Finger guards give protection to BS 848 Part 5. Manufacture is controlled to BS EN ISO 9001 Standards. Impellers The impellers incorporate the latest in sickle blade aerofoil technology to ensure minimum sound and maximum performance. Impellers up to 400mm diameter are moulded from a composite polymer, impellers above this size are Aluminium. The motors and impellers are factory matched, statically and dynamically balanced to ISO 1940 part 1, Quality Class G.6.3. Motors The external rotor motors are specifically designed and styled for this range of fan. Ball bearings are greased for life. Sizes 315 – 710 motors are protected to IP54 against dust and moisture, complying with BS EN 60529. They have ribbed aluminium body castings for efficient cooling with Motor insulation to Class ‘F’ (from -40°C to + 70°C). Speed controlled sizes 450 to 710, 6 & 8 pole motors are only suitable for operating temperatures of up to 40°C. Electrical The Sabre ®Plate Mounted Sickle fan range is available for either singlephase 220-240V 50 Hz capacitor start and run or three phase 380-415V 50Hz. Motors are fitted with Thermal Overload Protection which should be wired into all controller circuits and into starter contactors to prevent motor damage due to overloading / overheating. Speed Control Units are suitable for speed control by either electronic, voltage reduction or frequency inverters where permissible. For optimum efficiency and controllability Vent-Axia recommend the use of the eDemand Inverter controller to give close control via sensors or manual control. Form of Running Plate mounted fans (ex-stock) are supplied for extract use (Form ‘A’ running). Performance The fan performance is in accordance with tests to ISO 5801.

A first within the H&V industry, Vent-Axia’s New Kitchen Axial Fan range provides such a solution offering robustly engineered fans and motors designed and tested for operation at elevated temperatures (up to 70˚C induct) whilst utilising speed control. Utilising Vent-Axia’s advanced eDemand Inverter controls provides accurate and reliable control functionality whilst offering substantial running cost reductions and noise control. Availableinfoursizes: 450, 500, 560 and 630mm diameter with a performanceenvelope from0.65m3/sto5.93m3/s and pressure development of up to 600 Pa. Ensuring a compact design, the units have been constructed from a single sheet of steel, with a single 2 pole motor and axial impeller mounted within the length of the unit casing. The unit is manufactured from electro welded steel with an epoxy paint finish. Factory assembled to BS EN ISO 9001 ensuring a quiet and vibration free unit. All sizes are protected with a tough black epoxy paint finish for those harsh environmental conditions, internally or externally. Ensuring ease of installation the motor is wired directly into a single IP65 terminal box. Axial Impellers The impeller is manufactured in die-cast aluminium and fitted with narrow profiled blades, which provide the maximum efficiency at the maximum airflow. Airflow is Form A to ensure maximum cooling airflow over the motor. Motors Specifically designed for this range of fans and the expected environmental conditions. Greased for life ball bearings with temperature resilient grease specially selected to operate at the elevated temperatureslikely to be encountered in kitchen applications whilst allowing the fans to be installed at any angle. Rotors are dynamically balanced to ISO 1940 grade G6.3. Motors are protected to IP65 against dust and water jets complying with BS EN 60529. They have ribbed aluminium body castings and are mounted towards the airstream for efficient cooling. Motor insulation is Class ‘H’ (from -40°C to +70°C). All models are speed controllable by either voltage control or frequency inverter (see electrical section for details). Electrical Single phase 220-240V/50 Hz. Capacitor start and run. Three phase 380V-415V/50Hz. All motors are fitted with Standard Thermal Overload Protection (S.T.O.P), which should be wired into all controller circuits and into starter contactors. Terminal Box IP65 terminal box is supplied with all models with 20mm PGII entry. Performance The fan performance is tested and certified in accordance with BS 848 Part 1 1980. Sound Levels Fan sound levels, measured in a reverberant chamber in accordance with BS848 part 2 published dB(A) figures are free field sound pressure levels at 3m with spherical propagation at reference level of 2 x10–5Pa (20 micro-pascal).

276 Bifurcated Case Axial Fans (BIFA) •Sizes 250 to 1000 dia •Motors protected to IP55 •Motor insulation Class ‘F’ •Maximum ambient temperature 200˚C •Speed controllable via transformer or inverter (when theambient air temperature is not higher than 60˚C) •IP55 terminal box •Suitable for relative humidity levels up to 95% RH •Manufactured to BS EN ISO 9001 •Performance tested to BS 848 parts 1, 2 and ISO 5801 •2 Year Guarantee The Bifurcated Case Axial range has been specifically developed to meet the need for an axial fan which can handle atmospheres normally detrimental to the life of the fan motor. By isolating the motor from the system airstream, the bifurcated fan can handle a wide variety of saturated and dust-laden atmospheres, heated air and hot gases. The range has a split airway with a direct driven motor operating in ambient air within the motor compartment.They are suitable, as standard, for handling air temperatures up to +200˚C. The Bifurcated Case Axial Fan range has a number of accessories available which include: Axial Ancillary Pack, Attenuator, Wire Inlet Guard, Coupling Flanges, Mounting Feet, AV Mounts and Speed Controllers. Motors The motors are specially selected to operate within the motor compartment with the airstream in the duct system, at an elevated temperature. Motors are of the B3 foot mounting type, totally enclosed and fan cooled. Being foot mounted the motors can, in the event of a failure, be readily interchanged with a comparable frame size from a wide range of manufacturers to cover temperatures of up to 200˚C. Where indicated, the motor is suitable for speed control by either an inverter or a 5-step auto transformer speed controller when the ambient air temperature is not higher than 60˚C. Electrical Single phase 220-240V/50 Hz supply are available in two sizes 250 and 315 dia. in either 2 or 4 pole versions.Three phase 380-440V/50Hz supply are available in nine sizes 250, 315, 400, 500, 630, 710, 800, 900 and 1000 dia. in either 2 or 4 pole versions (710, 800, 900 and 1000 dia are only available as 4 pole). Impellers and Casing The aluminium alloy impellers are die cast and have an adjustable pitch which allows a wide range of air outputs to be selected. All the casings are manufactured in steel and hot dipped galvanised to BS EN ISO 1461 after fabrication. Motor mountings and fixings used in the assembly of the fan are zinc plated and passivated. Form of Running Bifurcated fans have arrows showing the direction of the impeller rotation and airflow. All models are Form B running. Terminal Box To IP55, protected against dust and water jets from any angle, allowing outside applications. Performance Tested to BS 848 Part 1 & 2.Published dB(A) figures are free field sound pressure levels at 3m with spherical propagation at a reference level of 2 x 10–5Pa (20 micro-Pascal). The inlet and outlet sound power level spectra figures are dB with a reference of 10–12 Watts (1 pico-Watt). Cooling External cooling is provided by a fan mounted at the non-drive end of the motor, protected by a cover with a grid air intake. The airflow, guided by the fan cover, is directed longitudinally on the entire periphery of the motor in the channels formed by the frame ribs. Adequate space is provided within the motor compartment to ensure a plentiful supply of cooling air.The air within the motor compartment must not exceed 40˚C. For ambients in excess of this, please consult our Technical Services Department for further information.

In-line Fans The Vent-Axia in-line fan range features both box and tube fans designed to provide controllable environmental management solutions for commercial and industrial applications. With sizes ranging from 100mm to 710mm diameter and air volumes up to 5.63m 3 /soptimum performance at minimum running costs is assured. Where noise is an issue, our ACQ range has been updated to include backward curved fans for energy efficiency and a highly sound absorbent acoustic foam to minimise breakout and induct sound levels, yet maintain a low profile for ceiling void applications. Designed specifically to fully comply with the new Building Regulations for Commercial Kitchens and fully tested within the aggressive conditions observed in commercial kitchen applications the EKF range with its EC motor out of the airstream achieves low specific fan powers ( 1.0w/l/s), has a multi spigot arrangement and is suitable for 120°C in duct temperature.

304 Lo-Carbon Kitchen Box Fan (EKF) •Energy efficient EC motor •120°C airstream rated •Sealed for life motor •Flexible installation, straight through or turn through 90° as standard •Internal or external mounting as standard •25mm Double skin casing •Integral IP65 Isolator •Simple potentiometer control •Compliant part L 2013 SFP for requirements for kitchenventilation systems Vent-Axia’s latest product offering in the Non Residential sector is a centrifugal box fan specifically designed for kitchen operation at elevated duct temperatures of up to 120°C. Working closely with our Engineering partner, the motor impeller arrangement has been specifically engineered to benefit from the efficiencies of an EC external rotor motor mounted out of the airstream to allow for operation at 120°C induct temperatures. Construction The casing is constructed from a framed 25mm double skin with acoustic insulation to minimise unit noise.With careful thought to maximising the installation possibilities from one unit Vent-Axia have managed to create a single unit that is suitable for both internal and external mounting as standard. In addition to this the duct configuration can be either straight blow through or turn through 90° and with the motor shaft either horizontal or vertical this enables the fan to be mounted in any orientation. Motor The Kitchen Box Fan range is powered by highly efficient, electronically commutated (EC) motors with permanent magnets, exceeding the minimum efficiency requirements for IE3 motors. All units are fully speed controllable via the onboard electronics utilising a 0-10V input signal. Motors and the onboard electronics are protected to IP54 as standard mounted and are out of the airstream. The combination of an EC high efficiency motor and a high efficiency backward curved impeller ensures ERP 2015 compliance. Impeller A backward curved welded Aluminium impeller is mounted on an extended shaft from the EC external motor. Motor and impeller is balanced as a finished assembly to G2.5 to ensure vibration free operation. Impeller matched to inlet cone for optimum performance. Speed Control By utilising EC motors the EKF range has been designed for simple Demand Ventilation control facilitated by use of a 0-10V potentiometer. This low voltage controller can then be mounted within the kitchen area thereby removing the risk of overheating or damaging the control cicuits. Performance The fan performance has been tested in accordance with ISO 5801 DIN 24163. Sound Levels Fan sound levels were measured in a reverberant chamber in accordance with EN ISO 3745. Published dB(A) figures are free field at a distance of 3m with hemispherical propagation at a reference level of 2x10 -5 . The sound power level spectra figures are dB with areference level of 10 -12Watts. Electrical Depending on unit size the EKF range is suitable for either single phase 220-240V 50Hz or three phase 380-414V 50Hz. All mains wiring is direct to the built in IP65 isolator mounted on the motor support plate providing simple and safe connection and operation.

SentinelD-Box The Sentinel D-Box from Vent-Axia is the answer to key problems such as ‘Why ventilate a room you’re not using?’ or ‘Why over ventilate a room with only one or two occupants inside?’ Sentinel overcomes many of the issues encountered with a traditional fixed volume ventilation system that is either On or Off irrespective of the number of people in the room, risking room over ventilation, burning valuable money and is a wasteful use of energy. The Sentinel system from Vent-Axia benefits the commercial building by providing: •Lower energy consumption than traditionalsystems •Reduced losses to ventilation under partoccupancy•Longer running life•Reduced operating costs•Savings in lifetime maintenance costs•Ease of installation

358 Sentinel is a range of ventilation systems for multi-occupancy and intermittently used rooms. Using energy efficient ducted fans with intelligent sensing and control, the system meets the ventilation requirements of both new builds and refurbishment projects.Ideal for applications where rooms are used at different times of the day by a variable number of people, the Sentinel system will monitor occupancy, ventilation rate and air quality, and respond accordingly to maintain the atmosphere within preset limits. Typical Applications A network of hotel bathrooms, flats or apartments, which require ventilation, but are only used in limited periods particularly in the morning and in the evening.School classrooms and lecture theatres which are only occupied during lesson time by a variable number of students, but when used must keep CO 2levels within prescribed limits.Office meeting rooms or open plan areas which are used periodically during the day by a variable number of staff and visitors, but when occupied must meet required airflow rates.Automatic sensing and control runs the system according to the maximum demand requirements of the building zone, whether it be carbon dioxide levels, temperature, humidity or air quality – triggered by people entering or leaving the rooms. Common configurations include Electronic Static Pressure (ESP) controllers for constant pressure systems. System Control The precise control of the Sentinel system, driven by the ventilation requirements of the room means that the system is only running to the level required and only using energy when it is needed. A range of sensors are employed to determine the occupancy of the rooms and manage the system ventilation rates accordingly. This optimises the use of energy whilst meeting the legislation requirements of the building. This compares to a ‘traditional’ fixed volume system, which in general is either ‘ON’ or ‘OFF’ often using energy to ventilate an empty or half occupied room, over ventilating and wasting energy. System Overview The Sentinel System is made up of 3 parts: EC/DC Fan Motor, Sentinel Integral Control Unit, Sensors and Controls. The ventilation demands of the room are detected by the wall, ceiling or duct mounted Sentinel sensors/switches. These communicate with the Sentinel control unit, which in turn drives the fanto the required speed to deliver the airflow. As the ventilation is provided to the room the sensors continuously feedback to the control unit, driving the fan motor to the exact level required in the room at any one time. Accessories For duct accessories refer to Accessories Section. Sentinel D-Box Fans •Ideal for multi-occupancy and intermittently used rooms •System only runs to level required •Avoids over-ventilation •Reduces energy use

359 Typical network of hotel bathrooms/flats/apartments Typical school classroom Typical office plan with conference facilities System Technology Sentinel demand ventilation is a closed loop controlled ventilationsystem. Employing a range of sensors to manage the system, demandis sensed by PIR, temperature, humidity, air quality or carbon dioxidesensors. Depending on the levels in the rooms, Sentinel’s fan speed isramped up or down to control the parameters within the required limits.If the room is unoccupied, the system switches off, saving energy andcost to the business. Available in single or twin fan configurations, withtwin allowing for load sharing or ‘standby’ for extra reliability. EC/DC Energy Saving Fan Motor Technology Sentinel utilises the latest EC/DCmotor technology, which providesenergy saving benefits even overDC motors. This technology is also infinitelyspeed controllable and offersincreased energy savings acrossthe complete speed control rangewhen compared with conventional inverter drive solutions. The resultis higher efficiency, reduced noise, accurate controllability, betterspeed control drawing less power and as a result better overall systemperformance. Sentinel can be used in a hierarchal system where maximum demand,for example temperature and/or CO 2gives priority control of the fanspeed or a constant pressure system with room mounted PIR/grilles orin-line damper control.

SentinelTotus 2D-ERV Following on from the highly successful award winning Sentinel demand ventilation system, Vent-Axia has taken the next step by incorporating the Sentinel demand control philosophy with a state of the art high efficiency heat recovery cell to create the Sentinel Totus 2D-ERV,Demand EnergyRecovery Ventilation System. Sentinel Totus 2D-ERV incorporates the same‘Sentinel’ high efficiency EC/DC backward curved motors/impellers, Sentinel Demand Controlled ventilation strategies and a market leading high efficiency counterflow heat recovery cell which achieves up to 90% energy recovery.The Energy recovery capabilities are independently tested and rated to EN308. Sentinel provides a solution to the common problem of ‘Why ventilate a room you’re not using?’ or ‘Why over ventilate a room with only one or two occupants inside?’ Sentinel overcomes many of the issues encountered with a traditional fixed volume ventilation system that is either ON or OFF irrespective of the number of people in the room, risking over ventilation, burning valuable money and is a wasteful use of energy.

Sentinel Totus 2D-ERV 396-401

386 Sentinel Totus 2Demand Energy Recovery Ventilation (D-ERV) is a newheat recovery demand ventilation system designed to meet modern building management control principles. It responds to the exact ventilation requirements of a room at any one time providing airflow only when it is required and to the level that is required, therefore using only the energy that is needed; no more no less, whilst recovering maximum energy from the extracted air and transferring it to the fresh supply air. This overcomes many of the issues encountered with a traditional fixed volume ventilation system that is either ON or OFF irrespective of the occupancy of the room, risking over ventilation, burning valuable money and is a wasteful use of energy. There is an additional benefit to this demand controlled lower speed running, one of reduced noise intrusion, something that in today’s society is becoming more important to end users. Vent-Axia’s dedicated HEVAC team offers: ✓Practical advice on HEVAC selection and installation ✓Guidance on solutions to meet legislation requirements✓Project management and site deliveries ✓After sales support and maintenance information The need to recover energy The high efficiency cell incorporated within the Totus 2range achievesa market leading 90% efficiency (EN308 independently tested). This enables Sentinel Totus 2to recover a third more energy than a 70%efficient device. This high efficiency means that heating and cooling loads associated with ‘extract to waste’ type systems can be reduced by up to 25% in both heating and cooling seasons. This high efficiency also means that expensive after heaters, often required in lower efficiency heat recovery devices, are now not required.The need to save costs Rising fuel prices are placing an increasing burden on organisations as they seek to reduce consumption. Sentinel Totus 2DERV features: ✓High efficiency heat exchanger – up to 90% energy recoveryoffering savings of up to 25% on heating and cooling loads ✓Integral automatic summer bypass - providing free coolingduring summer ✓Single skin construction with 95kg/m 3thermal and acousticfoam insulation (Maxi unit double skinned) ✓Low stand by power only 0.6W ✓Energy efficient EC/DC motors - 1/3 less energy lost to heatthan a conventional AC motor ✓ERP 2015 compliant fans Welcome to the world ofSentinel Demand EnergyRecovery Ventilation

387 The need for system integration With the drive towards ‘whole building cost’ philosophy maintenance schedules and costs are all now essential elements of the project in addition to the initial capital costs. Sentinel Totus 2D-ERV incorporates anumber of integrated features to offer maximum flexibility during design, build and operation including: ✓Air conditioning interlock – to optimise energy recovery ✓Heating system interlock – summer bypass optimisation ✓Interfaces for BMS control and monitoring ✓EC/DC motors with lower maintenance requirements andlonger service life ✓Aluzinc casing - suitable for external installations as standard ✓Optional cowl for roof mounting ✓Integral condensate pump – reduces installation costs andspace requirements ✓In-built automatic frost protection – prevents heat exchangerfreezing at very low temperatures ✓Ability to utilise the frost heaters as top up heat removing theneed for additional duct mounted heaters ✓In-built backlit LCD user control interface which can be remotelymounted to suit site requirements ✓Night time purge facility to reduce overheat during warmsummer periods The need for better health Removal of pollutants, such as moisture, carbon dioxide and external fumesare all important factors in maintaining indoor air quality. Studies within schools have demonstrated that maintaining lower carbon dioxide levels helps create a better learning environment.✓Hierarchical control maintains CO 2levels within levels describedin Building Bulletin 101 ✓Low sound levels meet requirements of Building Design ✓Automatic up to 100% summer bypass providing freesummer cooling ✓Demand control optimising indoor air quality ✓Closed loop control system ensures maximum comfort levels atminimum energy levelsThe need to meet legislation The Energy Performance of Buildings directive is implemented through the UK building regulations.

391 Demand control Precise control of the Sentinel Totus 2D-ERV system, driven by theventilation requirements of the room at any one time, means that thesystem is only running to the level required, using energy when it isneeded. A range of sensors are employed to determine the occupancyof the rooms, and manage the system ventilation rates accordingly. Thisoptimises the use of energy whilst meeting the legislation requirementsof the building. This compares to a ‘traditional’ fixed volume system, which in generalis either ‘ON’ or ‘OFF’ often using energy to ventilate an empty or halfoccupied room, over ventilating and wasting energy. System overview The Sentinel Totus 2D-ERV system is made up of 4 elements: ✓Up to 90% energy recovery (EN 308) ✓Low energy EC/DC motors ✓Sentinel Totus 2D-ERV, Demand Energy Recovery control ✓Sensors and Controls The ventilation demands of the room are detected by the wall or ceilingmounted Sentinel Totus 2D-ERV sensors/switches. These communicatewith the Sentinel Totus 2D-ERV unit, which in turn drives the fanto therequired speed to deliver the airflow. As the ventilation is provided tothe room, the sensors continuously feedback to the control unit, drivingthe fan motor to the exact level required in the room at any one time. Hierarchical control The system is controlled by on board electronics, with an LCDdisplay showing fan status and allowing for simple commissioningand installation, whether as a local sensor control unit or linked into abuilding management system. The LCD display unit can be remotelymounted if required. 1. Switched on/off or minimum/maximum level control. In anenvironment such as an office, the system is activated and runs betweenminimum and maximum levels by a choice of sensors: •PIR Detector • Thermostat • Humidistat •BMS (remote enable) 2. Hierarchical – maximum demand multi sensor input used witha combination of sensors, with a defined level of priorities tosimultaneously control a number of atmospheric conditions within aroom, such as a meeting room: • CO 2 /temperature – room mounted • CO 2– duct mounted •Building Management System (0-10V) Constant pressure extract Applied in a discreet central extract system, such as hotel bathrooms orapartment blocks, the system grilles and/or duct dampers are controlledby the presence of a person in the room or by achieving required levelsof humidity. The central system will respond to the demand dependingon the number of active rooms. •PIR/Humidity Extract Grille 125mm •PIR 12 - 70m 3 /h •Humidity: 12m 3 /h – 30% RH to 70m 3 /h -75% RH •Motorised Duct Dampers 100mm - 315mm DiaBuilt in end stop adjustment for setting minimum and maximumvolume.24V Min/Max or 0-10V proportional control options.

392 The Sentinel Totus 2D-ERV units are manufactured from Aluzinc sheet andare suitable for internal or external mounting as standard.System technology Sentinel Totus 2D-ERV is a closed loop controlled ventilation system.Employing a range of sensors to manage the system, demand is sensedby PIR, temperature, humidity, air quality or carbon dioxide sensors.Depending on the levels in the rooms, Sentinel Totus 2D-ERV’s fan speedis ramped up or down to control the parameters within the required limits.If the room is unoccupied, the system switches off, saving energy and costto the business.The unit standby power consumption is only 0.6 Watts. The EC/DC energy saving fan motor technology ✓Compliant to ERP 2015, future proofed fan and motor assemblies✓Higher efficiency at full speed - at 50% reduction inmotor speed gives an 87.5% reduction in power usage ✓Continuous speed control across the full operatingrange giving an increased tolerance to high andlow pressure ✓Low noise compared to a step control motor ✓Power input lost as heat is reduced by 1/3 comparedto a conventional AC motor ✓Lower maintenance requirements and longerservice life Sentinel Totus 2D-ERV utilises the latest EC/DC motor technology, whichprovides energy saving benefits even over DC motors. This technology is also infinitely speed controllable and offers increasedenergy savings across the complete speed control range whencompared with conventional inverter drive solutions. The result is higherefficiency, reduced noise, accurate controllability, better speed controldrawing less power and as a result better overall system performance.Volume reduction also increases energy recovery efficiency beyond thepublished figures. Sentinel Totus 2D-ERV can be used in a hierarchical system wheremaximum demand, for example temperature and/or CO 2gives prioritycontrol of the fan speed or a constant pressure system with roommounted PIR/grilles or in-line damper control.

422 Lo-Carbon Energy Saver MX Roof Fans (MX) •Reduces your carbon footprint •Three stylish diagonal discharge models •70% energy savings •Customised performance from 2200m 3 /h to 6700m 3 /h•Can be remotely monitored •Designed for easy inspection access for cleaning,maintenance or servicing •Long life DC motor The Lo-Carbon MX Roof Range offers longer life, lower maintenance and energy savings to a variety of commercial and industrial applications. Three stylish diagonal discharge models MX10, MX20 and MX30 offer customised performances up to 5,500m 3 /h. The units are moulded in tough recyclable material, fully UV stabilised and are suitable for arduous external conditions. The design features a mixed flow impeller with the motor out of the airstream and a slanted diagonal discharge pattern which creates an upwardly spiralling discharge pattern. Suitable for horizontal mounting only (max. of 3° from horizontal). Motors At the heart of the range is the latest Lo-Carbon energy saver DC technology, eliminating the need for expensive transformer controllers to achieve customised duties. Due to the Lo-Carbon DC design, the motors run cooler, prolonging the life of the bearings and motor lubricants. The motor is integral to the mixed flow impeller and is designed for ambient duct temperatures up to +80°C. MX motors are up to 80% efficient in converting energy into rotation, providing large energy savings throughout the speed range. They are also precisely controllable, typically offering energy savings of 40-60% compared with AC equivalents. On Board Control The electronics in the Lo-Carbon MX range offer the possibility of setting any working point/speed whenever required without a controller. The standard unit is ready to connect to a single phase electrical supply. However, an ideal working point can be set either at the factory or on site to suit a system duty. If the system resistance or volume requirement changes, the fan duty can be re-programmed to meet this new performance on site. Traditional AC products are tied to 4, 6 and 8 pole models and costly transformers – the Lo-Carbon MX is simply set up at the desired speed and, if required, can be controlled using inexpensive switches connected by four core low voltage wire. The Lo-Carbon DC system can be controlled downto much lower speeds than AC motors providing very quiet performancewhen required. Maintenance Vent-Axia Lo-Carbon MX units have a built in fault diagnosis system. An installation of several units can be interconnected using simple two core wire to form a BUS network for flexible remote maintenance monitoring tailored to meet your needs. Vent-Axia MX maintenance software is available, the installation can be used on a laptop/PC. Alternatively a hand held diagnostics/programmer is available for on site use. Lo-Carbon MX units have their own encoded signature, allowing ease of identification and full performance history access.Vent-Axia’s Lo-Carbon MX range is designed for easy inspection access for cleaning. Four screws secure the main cover. Disconnect the internal mains plug and four bolts release the chassis holding the fan/motor assembly and the electronic module.The Lo-Carbon MX range is constructed from fully recyclable plastics. The diagonal vortex discharge pattern throws air and sound upwards and away from the roof surface.

448 The RSC ELV (Extra Low Voltage) two speed selector has been especially developed for use with Industrial products to offer energy saving on all ventilation systems. Typically, ventilation systems are designed to cope with periods of peak demand, extracting expensively heated and conditioned air even through periods of low occupancy. Vent-Axia’s Two Speed Selector works by switching the power source between mains supply and a speed controller enabling reduction in the volume of air extracted during periods of low demand. The selection of power can be achieved by a Vent-Axia sensor or timer with volt free contacts or via a relay from the BMS (Building Management System). Connections between the RSC and the sensor are Extra Low Voltage. The RSC ELV two speed selector comprises of three modules, the RSC controller (103 14 230A)an electronic or 5-step auto-transformer appropriately rated to suit the fan and a Vent-Axia compatible sensor. The two speed changeover of the RSC ELV 24 is controlled by Vent-Axia compatible auto sensors utilising Extra Low Voltage wiring. With up to five speeds being available selected from a 5-step auto transformer controller. Electrical 9 Amp maximum rating on single phase 220V-240V/1/50Hz and three phase 380-415V/3/50Hz.
