DALLAS - AAF International is introducing its DuraShield™ Cartridge Filter. The DuraShield Media used in the cartridge filter is a proprietary high-strength, polyester reinforced media with a fluorocarbon meltblown outer surface layer that allows AAF to offer a high-efficiency Minimum Efficiency Reporting Value (MERV) 15 for this type of cartridge filter.
AAF designed DuraShield as a surface-loading media that achieves optimum particulate release during pulse cleaning. The synthetic fibers used throughout the media have been developed not to disintegrate, unlike some surface-bonded media, in order to withstand the rigors of repeated pulse cleaning cycles. These features are coupled with low initial pressure drop and high moisture resistance.
