The HemiPleat FR Carbon dust collector filter from Camfil Air Pollution Control (APC) combines flame retardant and conductive properties in a single filter. The carbon-impregnated filtration media is designed for dust-handling applications that require flame resistance and dissipation of static charges, including many metal dusts; fumed silica dust; plastic, PVC or composite dusts; pharmaceutical dusts and carbon black/toner dusts. 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, according to the company.
The "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 offers a MERV 15 efficiency rating and enhanced performance on difficult dust/fume applications and highly explosive processes.
