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 show s 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 fresh outside 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, Ventilat ion 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 higher ventilation rate for properties below 5m 3 h/m 2 (tighter properties) . The practical 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 2 or 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 maximum noise 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 efficiency standards are aimed 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 or replacement 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 fro m 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 at www.vent-axia.com/erp The 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 produ ct 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 described as 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 there is 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/ATQ QP/QPTW We 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 – rational ised 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 2 and ERV-HIBOX ranges are unaffected by these changes, 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 continu e 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 sys tems 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 will be 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 cen tral 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 all Vent-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. Functions Light 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 is only 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 sensor via the App. Silent schedulin g 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.

16 Lo-Carbon iQ • Minimal retro design to match bathroom décor • Extremely quiet- only 21 dB(A) • Truly surface mountable with removable spigots • Intelligent controls and control panel for easy and flexible set up and commissioning • Low power consumption – only 5 W • Easy cleaning and maintenance • 5 year Lo-carbon motor guarantee • Intelligent humidistat control as standard • Innovative airing function to ensure good air quality • IP44 rated Market Leading Design With the launch of the Lo-Carbon iQ fan, we not only spent time perfecting the operation and user's experience of the fan but also worked hard on the design. 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 sil ent 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 cle an and clear the fan eg 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.
