The new HemiPleat filter offers extended service life and lower pressure drop compared to standard dust collector cartridge filters, according to this company. The HemiPleat line includes filter elements that fit virtually all types of new and existing cartridge dust collectors. A media pack design holds the pleats of the cartridge open, which helps to use more of the media surface for filtration. The wide, uniform spacing results in lower pressure drop and the design causes dust to release more readily from the cartridge during pulse cleaning and uses less compressed air for many applications, says the company.
