  1. 1. Camfil Farr Training Academy Webinar Programme 2011 <ul><li>Attend a free Camfil Farr Webinar from the comfort of your own office </li></ul><ul><li>Every Friday at 11am GMT </li></ul><ul><li>Register at </li></ul><ul><li>This webinar programme is aimed at assisting you with your business processes demonstrating how substantial energy saving opportunities can be made. Each Webinar lasts no more than 30-45 minutes and is free of charge. </li></ul>© CAMFIL FARR 11-07-05
  2. 2. Low Energy Air Filters © CAMFIL FARR 11-07-05 2010 global sales £430 million 24 Production Plants, 4 R&D Centres 3400 employees Production Facility ● Sales Office ● Agent ● Head Office ●
  3. 3. Trends in population Energy demand Energy use Source : House of Commons and BP energy report OECD : Organisation for Economic Cooperation and Development (12+14 countries) The tonne of oil equivalent ( toe ) is a unit of energy : the amount of energy released by burning one tonne of crude oil, approximately 42 GJ
  4. 4. <ul><li>Camfil Farr Low Energy Air Filters save Money, Energy and Carbon </li></ul>But also deliver Sustainable Air Quality
  5. 5. © CAMFIL FARR 11-07-05 Energy has risen in price by 118% from 2006 to 2011 (Mike Malina - Energy Solutions) That is an average rise of about 16% per year over 5 years during a world recession. Will Energy prices rise more over the next 5 years?
  6. 6. © CAMFIL FARR 11-07-05 Guys Campus Land Securities manual monitoring confirms pressure drop reductions when upgrading to Low Energy Air Filters. Kings College – Guys site confirms reduction of pressure drop gives energy use reduction with drop in Fan kW.

  9. 9. © CAMFIL FARR 11-07-05 Monitoring by manual readings give pressure drop reductions
  10. 10. © CAMFIL FARR 11-07-05 Comparison of pressure drop readings confirm reduction for Low Energy Air Filters
  11. 11. © CAMFIL FARR 11-07-05 Existing filters were measured for pressure drop 01) Ahu1 has synthetic filters
  12. 12. © CAMFIL FARR 11-07-05 Low Energy Air filters were measured for pressure drop 07) Enhanced pocket area give lower pressure drop
  13. 13. © CAMFIL FARR 11-07-05 Sustainable Air Quality with less energy Low Energy Air Filter – consistent media performance delivers sustained cleaner air with over 4 X reduction in fine dust particulates
  14. 14. © CAMFIL FARR 11-07-05 Land Securities own and manage 29 million ft2 of Commercial property. Camfil were asked by Neil Pennell Engineering Director of Land Securities to evaluate the cost saving and energy saving benefits of installing Low Energy Air Filters.
  15. 15. The Mobile Energy monitoring unit provides a comprehensive monitoring system that enables energy usage to be compared to AHU volume flow and pressure drop Easy to position on most AHU’s Independent power source New Approach for Guys – The MEMU

  17. 17. Energy consumed by air filters The cost of ventilation <ul><li>The energy requirement for ventilation is expensive. </li></ul><ul><li>Filters account for approx. 30% of the total energy cost of the system. (C.I.B.S.E. data) </li></ul><ul><li>Filters are the most inexpensive part of the system to improve . </li></ul><ul><li>Without Capital Expenditure </li></ul>© CAMFIL FARR 11-07-05 Clean air with economic benefits 30% of total system pressure loss 40% 20% 4% Pascal

  19. 19. © CAMFIL FARR 11-07-05 Guys Campus The case studies show that Low Energy Air Filters save energy and clean air with greater efficiency. The program of remote monitoring is currently on five sites with ten more planned. Opportunity assessment surveys for energy reduction are taking place on a daily basis.
  20. 20. How we optimise our Low Energy Air Filter selection <ul><li>A Hi-flo F7 M7 Bag filter with 9.2 M2 of micro-fibre media has the optimum low pressure drop and consistent high particulate efficiency with a longer working life </li></ul>BS:EN13779:2007 advises F7 minimum efficiency
  21. 21. Life cycle costing & air system factors Energy is part of the LCC model <ul><li>The life cycle cost for the filter is the cost of the: </li></ul><ul><li>Filters </li></ul><ul><li>Labour </li></ul><ul><li>Energy consumption </li></ul><ul><li>Cleaning of ventilation system </li></ul><ul><li>Disposal of used filter </li></ul><ul><li>= LCC </li></ul>© CAMFIL FARR 11-07-05 Clean air with economic benefits
