RIVERDALE, N.J., Feb. 19, 2013 /PRNewswire-iReach/ -- HEPA, or high-efficiency particulate air filters, meet tough standards for efficiency, and must remove nearly 100 percent of airborne particles greater than 0.3 micrometers (99.97 percent, to be exact). Today they are widely used in medical facilities, industrial clean rooms, and other mission-critical environments. But when exposed to elevated temperatures, HEPA air filters can present multiple challenges for filter performance and filter integrity testing, with few black-and-white answers. To help HEPA filter customers get optimal use from their high-temperature filters, Camfil -- the world's leading provider of clean air solutions -- has published a new technical bulletin with recommendations and answers to common questions.
The bulletin -- "High Temperature HEPA Filters FAQs" -- is now available on the life sciences section of the Camfil website at http://airfilters.camfilfarr.us/high-temperature-hepa-filters-faqs_8577.html. It was produced by Sean O'Reilly, Camfil's global director of cleanroom & life science segment, with support from the company's US Director of Research & Development, Steve Devine, and addresses issues including HEPA filter burn-in, the primary applications of HEPA filters at elevated temperatures (including use in ovens and tunnels designed for use in the life sciences and microelectronics industries), the differences between silicone and ceramic sealed HEPA filters, filters created specifically for high-temperature use (such as Camfil's Termikfil design), how rapidly a high-temperature filter can be heated up or cooled down, and the life expectancy of a high-temperature HEPA filter.
