Camfil Farr Air Filtration India Ltd. Manufactures Cartridge Filters with Pleating Technology. Camfil Farr Air Filtration India Ltd. Manufactures filters and clean air solutions. The Cartridge Filters with Pleating Technology is used to manufacture the media packs of this cartridge which are unique and have never been applied to a cylindrical industrial dust collection filter before. Synthetic beads hold the pleats of the cartridge open with wide pleat spacing not found in competitive cartridges, which are packed too tightly to maximize media use. The wider spacing of the design exposes more media to the gas stream and results in lower pressure drop as well as improved cartridge release characteristics during pulse cleaning.
