Dust-collecting filters that are flame retardant and conductive

By Chemical Engineering | April 1, 2016

Camfil APC

The new HemiPleat FR Carbon dust-collector filter (photo) combines flame-retardant and conductive properties in a single filter. With high efficiency and a long service life, the cartridge filters are especially suited for 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 special carbon-impregnated filtration media is designed for dust-handling applications that require flame resistance and the dissipation of static charges. These include metal dusts, fumed silica, plastic or composite dusts, carbon black and more. The combined functionality of flame-resistance and conductivity can allow the use of dry-media-type dust collectors in applications where they otherwise could not have been used. — Camfil Air Pollution Control (APC), Jonesboro, Ark.
