A B C D E EN779:2012 and Energy Efficiency Classification New guidelines: higher indoor air quality and lower energy use The best of both worlds
AAF delivers AAF constantly pursues better air quality and lower energy consumption. And we are successful in this effort. Our air filters offer the best of two worlds: excellent performance in the area of air filtration ánd low energy consumption. AAF customers do not have to make concessions. AAF, your partner Advice from the AAF Technical Support Group When choosing an air filter, one should not only make sure that it meets the minimum efficiency requirements of the filter class in question. Although they may belong to the same filter class, no two filters are the same. If the ME is actually higher than the established limit value, the filter offers even higher air quality. And, with AAF, often in combination with a lower energy consumption. A double benefit!

EN779:2012 and Energy Efficiency Classification New guidelines: higher indoor air quality and lower energy use The new guidelines, EN779:2012 and Eurovent Energy Efficiency Classification, place high demands on the performance and energy consumption of air filters. The main advantage is that the same guidelines provide companies a better means of selecting the proper air filter. AAF therefore supports the new guidelines in its effort to improve air quality and lower energy use. The air filtration solutions supplied by AAF meet the requirements of both EN779:2012 and Eurovent with above-average performance. EN779:2012 classifies, Eurovent verifies The classification of an air filter has no value if it is not verified by an independent party. Eurovent therefore carries out an annual, i ndependent assessment to verify the promised performance of air filters, in accordance with EN779:2012. As a result, Eurovent certifies the filtration efficiency, pressure drop and energy efficiency. Manufacturers that participate in Eurovent, including AAF, are entitled to display the Eurovent logo: proof that their air filters live up to the promise based on the EN779:2012 classification. The EN779:2012 standard The European Committee for Standardisation (CEN) has established a new standard for testing and classifying coarse and fine filters, based on filtration performance, the EN779:2012. In doing so, the CEN counters the sale of poor-performance filters. The EN779:2012 distinguishes three categories: coarse (C), medium (M) and fine (F). The classifications are based on the minimum efficiency (ME) of a filter during the entire installation cycle. The ME is defined as the lowest value of three different tests for 0,4 μm particles: initial efficiency, efficiency throughout the test’s loading procedure and efficiency after discharging. The classifications for fine filters vary from F7 up to and including F9. Air filters that do not meet ME requirements are relegated to one or more lower categories, based on the new standard.

Eurovent, certification of air filters Eurovent Certification is the European association for certifying performance of air-conditioning and refrigeration products according to European and international standards. One certification programme is geared towards air filters, which are classified and sold as medium and fine filters M5, M6 and F7 up to and including F9, as defined in the EN779:2012 standard. Thanks to certification, customers have assurances that installed air filters actually provide the performance claimed by the manufacturers. AIR FILTERS CLASS M5-F9 AAF lives up to its promises AAF has had its air filters tested ever since the introduction of the Eurovent certification programme in 2007. Our filters have been certified since the start of this programme. Moreover, we submit the air filters to independent testing institutes such as SP and VTT because - apart from Eurovent Certification - we want to be certain that our products deliver the high air quality and low energy use for which they are designed and that they meet the stricter requirements of the EN779:2012. Our customers thereby receive double assurance that our filters perform as promised. Eurovent Energy Efficiency Classification 18% 2% On average, fans in air handling systems utilize 40% of the total energy requirements of a building. The air filters used in those systems consume 25% of their energy demand. No less than 80% of the total costs within the lifecycle of an air filter are energy costs. Low-energy filters therefore immediately reduce environmental impact and lower the Total Cost of Ownership (TCO). 80% Energy consumption labels Eurovent conducts independent tests not only to measure the air quality performance provided by filters, but also their energy efficiency. For this purpose, Eurovent introduced a new method in 2011 under the name Guideline 4/11: the Energy Efficiency Classification of Air Filters for General Ventilation Purposes. This method helps customers select the most energyefficient air filters. Eurovent bases its calculation on a test airflow rate of 3400 m3/h, a fan efficiency of 50% and an annual operating time of 6000 hours. The annual energy consumption measured is compared to the limits set for each filter class. Lifecycle costs air filters 80% Energy consumption 18% Investment and maintenance 2% Disposal With this method Eurovent can validate the claims of manufacturers concerning annual energy consumption of filters. The findings are awarded energy labels showing the Eurovent energy logo. This gives customers a guarantee that the product delivers what it promises.

Important guideline changes for 2014 More information For 2014, the Eurovent Energy Efficiency Classification has undergone several modifications, comprising the energy classification itself as well as the design of the energy label. The most notable changes are summarized below. You will find additional information about the Eurovent certification programme for air filters, along with an overview of AAF’s medium and fine filters, all of which are certified, at www.eurovent-certification.com. The number of energy classes has gone down from 7 to 5 classes. Class A remains the best level and class E has become the worst level; energy classes F and G have been removed. Also the limits between the energy efficiency classes have been modified with the exception of energy class A. This means that AAF’s A rated filters in 2013 remain A rated filters in 2014. The new 2014 energy label will show a different color coding of the energy classes. Class A is from now on displayed in blue instead of green and the worst class, now being E, is in brown instead of in red. In contrast to the 2013 energy label, which showed energy consumption ranges (e.g. 0 - 1200 kWh for an A rated class F7 filter), the 2014 energy label includes the exact energy consumption of the air filter. This makes it easier for customers to distinguish between an average A rated filter and an excellent A rated filter. Calculation of the annual energy consumption Not all manufacturers of air filters are allowed to display the new Eurovent energy label; only air filter manufacturers officially certified by Eurovent. AAF holds Eurovent certification since 2007. That is why we are a reliable, stable partner for our customers. W= W qv ∆p t η Bright blue A-labels AAF takes pride in the fact that it’s A-label air filters do not simply have standard A-labels, but often bright blue A-labels, which perform better than the limit value established by Eurovent for an A-label. When choosing a filter, it would be a good idea to compare these performance figures. The differences in annual energy costs between various A-label air filters could run as high as several tens of euros per filter per year. A bright blue filter pays for itself quickly simply as a result of its energy savings. 2013 label 2014 label qv . ∆p . t η . 1000 = annual energy consumption (kWh) = airflow rate (m³/s) = average pressure drop (Pa) = annual operating time (hours) = fan efficiency (%) Main label changes summarized 5 Energy classes instead of 7 Class A remains best, class E is worst Y IJA IE ENERGY EFFICIENCY IA EFFICIENCY CLASS DriPak® GX, 592x592x640-10 AIR FILTERS Mentioning of exact kWh values AIR FILTERS F9 F9 Initial efficiency 0.4 µm: 3400 m 3 /h 90 % Nominal airflow: Initial efficiency 0.4 µm: Minimum efficiency 0.4 µm: Annual Energy Consumption: 90 % Annual Energy Consumption: From 2000 kWh/annum To 2500 kWh/annum Minimum efficiency 0.4 µm: B C D E F G Eurovent 4/11 A 3400 90 90 1965 m3/s % % kWh/annum 2014 Approved – 14/09/2012 A I ntroduction year now included EN779: 2012 EN779:2012 Nominal airflow: New color coding of energy classes AAF AAF DriPak® GX, 592x592x640-10 THRESHOLD REFERENCE SCALE YEAR : 2014 Eurovent 4/11 Approved – 15/11/2013 ENERG
