The Graver Technologies TefTEC™ Series is an absolute-rated PTFE membrane cartridge filter engineered for high-purity gas, vent, and liquid process applications. Constructed with a hydrophobic expanded PTFE membrane and polypropylene support layers, TefTEC™ filters offer exceptional chemical compatibility and moisture resistance, outperforming traditional PVDF and polypropylene filters.

Designed for critical environments, each cartridge is manufactured and integrity tested in an ISO Class 7 cleanroom and flushed with 18 megohm DI water to ensure consistent purity. Available in micron ratings from 0.05 to 1.0 µm, these filters maintain high flow rates with a compact, single-layer construction that reduces system size and pressure drop.

Compliant with FDA CFR Title 21, USP Class VI, and EU Food Contact regulations, the TefTEC™ Series is ideal for chemical processing, pharmaceutical intermediates, fermentation air, hot DI water, and vent filtration. Offered by Total Filtration Services (TFS), TefTEC™ filters provide long-lasting, validated performance across critical process, laboratory, and industrial applications.
