The HemiPleat dust collector filter uses a carbon-impregnated media to capture dusts that generate static charges requiring dissipation (such as fumed silica, plastic, polyvinyl chloride (PVC), and carbon black dusts). Since it reduces the risk of ignition due to static electricity charges, the filter is also suitable for use in applications involving potentially explosive dusts. The conductive media is available in the full selection of HemiPleat cartridge styles, to fit virtually all new and existing cartridge dust collectors. It is said to be the only filter to combine conductive properties with a patented, open-pleat design, which results in better airflow through the cartridge and better cleaning characteristics. This, in turn, reduces maintenance and energy requirements.
