PTFE Membrane Filter Cartridge

TefTEC cartridge is a hydrophobic filters made of natural hydrophobic PTFE membrane and polypropylene support layers and components. PTFE Membrane Filter Cartridge are HIMA retentive that offers superior hydrophobicity and water intrusion resistance compared to PVDF and polypropylene membranes. The cartridge construction also offers a cost effective alternative to all-fluorocarbon filters. TefTEC filters are ideal for gas/vent applications and the filtration of aggressive chemicals and solvents. These PTFE Filter Cartridges are best fit for critical processes in pharmaceutical industries, chemical plants, beverages & syrups, distilled water plants, etc.

TefTEC filters are flushed with ultrapure Water, integrity tested and packed in ISO Class 7 cleanroom environment. The complete traceability is ensured by engraving of lot numbers on all filters, plus pore size identification on membrane filters to assist customer installation accuracy. TefTEC filters are validated as per international standard for use in direct contact with Pharmaceutical, food and beverage products i.e.USFDA CFR Title 21, USP Class VI etc.
