About this item

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.

  • Naturally hydrophobic PTFE membrane with superior water intrusion resistance
  • High surface area design provides excellent flow and reduced system size
  • 100% integrity tested and flushed with 18 MΩ-cm DI water
  • Manufactured and packaged in ISO Class 7 cleanroom environment
  • Certified for food contact and meets USP Class VI standards
