Conductive Dust Collector Filter Provides Static Dissipation

July 21, 2011
New HemiPleat® dust collector filter combines high filtration efficiency, long service life and energy-efficient performance with conductive properties. The manufacturer uses a special carbon-impregnated media designed for use where conveyed dusts generate static charges that require dissipation. Applications include fumed silica dust; plastic, PVC or composite dusts; and carbon black/toner dusts. Cartridge filters manufactured with carbon-impregnated media can also be used in 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. Conductive filters allow the use of media-type dust collectors in applications where they otherwise could not have been used, due to the dusts having low minimum ignition energy characteristics. The conductive media is available in the full selection of HemiPleat cartridge styles, to fit virtually all new and existing cartridge dust collectors.
