BP, BPHE and BN Series Filter Bags


• Thermally welded unique design results in consistent filtration efficiencies.
• Semi-rigid cylindrical design is easily crushed and incinerated.
• Higher productivity - faster bag “change-outs”.


Polypropylene bags are compatible with a broad range of corrosive fluids including organic solvent, 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 because of 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 monofilament materials are offered in nylon with micron rates of 50-800 and efficiencies from 75 to 95 percent. The materials are cleanable and reusable.
