  • Fumed silica dust
  • Plastic
  • PVC or composite dusts
  • Carbon black/toner dusts

HemiPleat vs. Competitor

HemiPleat conductive filters provide high filtration efficiency, long service life, and energy-efficient performance with anti-static properties. We use a special carbon-impregnated media designed for use where conveyed dusts generate static charges that require dissipation.

Conductive cartridges can also be used on dusts that are explosive to meet NFPA requirements for grounded media. The HemiPleat anti-static media is available in the full selection of HemiPleat cartridge styles to fit virtually all new and existing cartridge dust collectors. It is also the only filter to combine anti-static properties with an award-winning, patented open-pleat design. This results in better airflow through the cartridge and better cleaning characteristics, providing energy-efficient performance and long life.


HMPTC – PolyTech™ Conductive (color: black) – MERV 10 proprietary blend of cellulosic fibers and polyester fibers with a moisture-resistant silicone treatment for optimum dust release characteristics, yielding long service life at high filtration efficiencies. Chemically treated and impregnated with carbon for static dissipation.

HemiPleat Flame-Retardant, Conductive Media Option

This filter is the first to combine flame-retardant and conductive properties in a single filter that also offers high efficiency, long service life, and energy-efficient performance.

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. 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 offers a MERV 15 efficiency rating and enhanced performance on difficult dust/fume applications and highly explosive processes.
