The special carbon-impregnated filtration media is designed for dust-handling applications that require flame resistance as well as dissipation of static charges – including many metal dusts; fumed silica dust; plastic, PVC or composite dusts; pharmaceutical dusts and carbon black/toner dusts. Camfil says the cartridge filters are especially suited to explosive dust applications, making it possible to conform to NFPA and ATEX requirements and lessen the risk of ignition sources due to static electricity charges. The new “two-in-one” conductive/flame retardant filters often allow the use of dry media-type dust collectors in applications where they otherwise could not have been used. They are available in a choice of two media types: the standard HemiPleat open-pleat high efficiency media, or the HemiPleat eXtreme nano fiber media, which Camfil says offers a MERV 15 efficiency rating and enhanced performance on difficult dust/fume applications and highly explosive processes.
