HemiPleat high-efficiency filter

The HemiPleat high-efficiency (HE) filter offers an unsurpassed minimum efficiency reporting value (MERV) 15 rating, coupled with up to twice the service life and half the pressure drop of standard dust collector cartridge filters. Available in filter sizes to fit any cartridge collector, the HemiPleat HE media is ideal for the capture of toxic and other ultra-fine dusts, and for applications where process air is recirculated downstream of the collector for energy savings. The filter combines the HemiPleat technology with an HE synthetic fine-fiber media that yields a filtration efficiency of 99.999% for 0.5-mm particles and larger. A patent-pending design holds the pleats of the filter 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 allows dust to eject readily from deep within the pleats during pulse cleaning.
