Pentek, Pentair BP420 Polypropylene Felt, Disposable Filter Bags

BP Series Filter Bags feature a thermally-welded, unique design that results in consistent filtration efficiencies. They are designed to fit the 410 and 420 Housings. Higher productivity can be achieved with faster bag change-outs. The semi-rigid cylindrical design is easily crushed and incinerated.

BP Series (Polypropylene Felt)

  • Filtration ratings from 1 to 200 microns to comply with any filtration requirement
  • Manufactured from felt due to its high solids loading capabilities versus 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 product a bond that reduces the possibility of migration
