HemiPleat filter

Compared to standard dustcollector cartridge filters, the HemiPleat filter typically doubles the life at half the pressure drop, according to the manufacturer. The key to the filter’s performance is a patent-pending pleating technology that has never before been used in the manufacture of a cylindrical dust collection filter. An innovative media pack design holds the pleats of the cartridge open, making virtually all the media surface available for filtration. The wide, uniform spacing results in lower pressure drop for more efficient performance. This design also causes dust to release more readily from the cartridge during pulse cleaning and uses less compressed air for many applications. Extensive testing shows that the HemiPleat cartridge also holds more dust than conventional filters, allowing a longer time period between cleaning cycles.
