Polypropylene bags are compatible with a broad range of corrosive fluids including organic solvents, oils, acids, alkalis and micro-organisms.

BP Series (Polypropylene Felt) Bags An assortment of filtration ratings is offered - from 1 to 200 microns - to comply with any filtration requirement.

The bags are manufactured from felt due to its high solids loading capabilities, in comparison to similar mesh fabrics. The media is created by needle-punching two layers of synthetic fibers together in a supporting scrim. A glazed finish, created by melting the outermost surface fibers, is used to produce a bond that reduces the possibility of migration.

BPHE Series (High Efficiency) Bags High efficiency bags are offered for those critical applications when high efficiency combined with high dirt-holding capacity is required. Polypropylene materials are processed into microfibers with diameters of 1-10 microns or more. These fibers are converted into filter material. Microfiber media are covered with spun-bonded polypropylene.

BN Series (Strainer) Bags Woven monofilment materials are offered in nylon with micron ratings of 50-800 and efficiencies from 75 to 95 percent. The materials are cleanable and reusable.
