  • Hello and Welcome to the Camfil Trainiing Academy and our webinar forum. The webinar today is designed to draw attention to the energy saving benefits of Low Energy Air Filters, particularly to you as Air Conditioning Inspectors. The EPBD or Energy Performance Building Directive for those of you who like long words offers a chance to identify worthwhile energy saving opportunities such as converting to Low Energy Air Filters.
  • The main area of interest to your client is to save money. This can be achieved with Low Energy Air Filters by reducing the cost of the filters over time because they last longer. The energy consumption is reduced because they have a lower pressure drop. The maintenance costs and disposal costs are reduced because the filters are longer lasting. Other system related costs are also reduced by use of Low Energy Air Filters. All these cost elements are included in the Eurovent Life Cycle costing model (LCC for short) Energy consumption can also be related to the environmental impact of increased levels of CO2 caused . The govenment CRC, Carbon Reduction Commitment is targetting large users of energy such as your clients and taxing them if the
  • We thank you for attending this webinar and would welcome any comments and questions you would like to send us regarding our Low Energy Air Filters. We would like to make our webinars as relevant and useful as possible to your Air Conditioning Inspections and the reports. Our Company Website has a lot of useful product and applications data. We also have white papers and further information on our specialist websites And especially fir Air Conditioning inspectors Our technical staff will be happy to help with any issues . We offer on site CPD training for groups of engineers and company staff. Please contact Anne Dempsey for details of the seminars offered. Take the opportunity offered by Low Energy Air Filters

    1. 1. Welcome to the Camfil Farr Training Academy © CAMFIL FARR 12-02-10 By the end of this webinar you will have an update on the new EN779:2012 standard and the opportunity to have clean Indoor Air Quality and energy efficiency with Low Energy Air Filters
    2. 2. EN779:2012 will be arriving Peter Dyment 07-02-2012
    3. 3. WHEN? <ul><li>The latest indications are the standard will be due for publication later this year. The situation will be updated over the next few months. </li></ul><ul><li>We are all trusting that a decision to proceed will be forthcoming so that our industry can make progress and plan for the future. </li></ul>© CAMFIL FARR 12-02-10
    4. 4. <ul><li>EN779 as a filter test standard has been with us since 1993 </li></ul><ul><li>and was updated in 2002. </li></ul><ul><li>What is EN779:2012 about and why is it important? </li></ul><ul><li>It is the updated European Standard that gives a laboratory test and class to benchmark HVAC air filter particulate efficiency. </li></ul><ul><li>It uses a test aerosol of 0.4 micron and ASHRAE dust to load (not test) the filter and increase air filter resistance in stages. </li></ul>© CAMFIL FARR 12-02-10
    5. 5. © CAMFIL FARR 12-02-10 EN779:2002 Test Rig The EN779:2002 test is usually performed by an independent test house on air filters up to F9 classification and a test report is issued. What is new in the 2012 update?
    6. 6. <ul><li>EN779 was revised in 2002 because of the problem regarding the inconsistent particulate life performance of synthetic media filters. </li></ul>© CAMFIL FARR 12-02-10 SINTEF test results Norway (1995) show real lifetime performance losses
    7. 7. <ul><li>Synthetic F7 Class filters have been marketed for many years but some a have a working particulate efficiency dropping as low as 10%. </li></ul><ul><li>EN13779 advises that F7 is the minimum filter class required for cleaning air and thereby making it safe to inhale. Clearly this standard assumes a consistent F7 performance. </li></ul>© CAMFIL FARR 12-02-10
    8. 8. © CAMFIL FARR 12-02-10 EN779:2012 has set the minimum particulate efficiency (ME) of 35% on an F7 grade filter. This will exclude inferior synthetic media HVAC filters. Min Effy. 35%

    12. 12. IAQ approach for 2012 © CAMFIL FARR 12-02-10 When the outdoor air quality has been categorized, EN13779:2007 clearly specifies the filter class that is required to achieve preferred indoor air quality: Recommendations in EN13779: 2007

    20. 20. Why a is there a risk in 2012 ? <ul><li>Traditional glass fibre media </li></ul><ul><li>F7 > 60% minimum efficiency – in built up environment </li></ul><ul><li>Synthetic F7 charged media – ME = 16-20% </li></ul><ul><li>Synthetic media has to improve to reach minimum 35% ME (minimum efficiency) – with increased pressure drop </li></ul><ul><li>New glass media >45% efficiency – lower pressure drop </li></ul>© CAMFIL FARR 12-02-10
    21. 21. <ul><li>Check the Indoor Air Quality Factor (IAQ factor) </li></ul>The IAQ factor is found by dividing the LCC by the ME. It tells you have much filter performance you are getting for your money. EG. M7 F7 bag = 24.7 IAQ G4 S-Flo-F7 bag = 154.6 IAQ IAQ Factor is 6.25 X per % Minimum Efficiency (ME)

    23. 23. What is the 2012 HVAC product opportunity? <ul><li>Synthetic media filters will have to improve to reach 35% minimum particulate efficiency (ME) – meaning an increased pressure drop </li></ul><ul><li>Reduce pressure drop with LEAF – keep minimum efficiency high (ME) usually about 55% to 60% for F7. </li></ul><ul><li>Never compromise on filter particulate efficiency ! </li></ul><ul><li>Save energy – better LCC – Eurovent Energy Classification Programme </li></ul><ul><li>That is an improvement opportunity ! </li></ul>© CAMFIL FARR 12-02-10
