This customized 18-inch-long polypropylene felt bag filter is engineered to provide superior sealing and filtration efficiency with advanced sealing technology: a polypropylene felt gasket is thermally welded directly to the flat top of the RP top flange. This addition eliminates leakage between the flange and the head of the housing for a bypass-free seal against the vessel. It is designed for compatibility with PBR-420BK filter baskets with a 3.75-inch ID for use in Pentek BPH-420-1 Big Blue type filter vessels.
Polypropylene felt liquid filter bags are supplied with a glazed finish to reduce fiber migration. Polypropylene felt's depth filtration properties can remove solid or gelatinous particles with temperature ratings up to 200 deg F. Handles are standard on all bags.
All polyester and polypropylene materials meet FDA regulations for food contact under CFR21, section 177.1520
