International Filter Products is offering 316L ETFE Lined Filter Housing filter vessels. The outer shell is 316L wetted surfaces lined with ETFE (Tefzel). The most internal components are constructed of PTFE Teflon. Ethylene tetrafluoroethylene (ETFE) is a thermoplastic copolymer derived from the polymerization of ethylene and tetrafluoroethylene (Teflon) monomers. These materials are extremely tough and abrasion-resistant, having excellent chemical resistance and continuous operating temperatures up to 150°C (300°F). ETFE is also an excellent electrical insulator and has good nonstick and low friction properties. The uniquely designed, 6mm thick-walled stainless-steel body maintains ASME BPE standards and allows operations under aggressive conditions. The Tefzel coating makes the housing compatible with highly corrosive chemicals.

FDA Regulation:
