HT TefloGas Filter Cartridges

Hydrophobic PTFE Membrane  ·  Sterile-Grade Filter for Critical Gas Filtration

HT TefloGas Filter Cartridges are composed of a PTFE membrane with advanced high-temperature-resistant core and internal adaptor. They are specially designed for air, gas, and vent sterile filtration at critically high temperatures.

Features and Benefits

  • Designed for Water Intrusion Test (requires no alcohol)
  • Oxidation-resistant materials provides longer service life in high temperature air and vent applications
  • Exceptionally high flow rates with low pressure drops
  • Part/Serial numbers are laser-etched and have 2D matrix code for easy tracking
  • Filter construction provides steam resistance at high temperatures

Quality Standards

  • Integrity Test correlates to ASTM F838-05 Bacterial Challenge Test (BCT)
  • Each filter is individually Integrity Tested prior to leaving the factory
  • Each filter is Fully Traceable with a unique serial number
  • Designed, developed and manufactured in compliance with ISO9001
  • Full Regulatory Compliance with the following:
    • 21CFR.210.3(b)(5)(6), 211.72 for Non-Fiber Release
    • Endotoxins: <0.25EU/ml/10inch filter
    • USP <88> Plastic Class VI-121°C
    • FDA 21 CFR177-182 & EU 1935/2004/EC

Typical Applications

  • Autoclaves
  • Fermented Inlet Air
  • Aseptic Packaging/Blow-fill Seal (BFS)
  • Hot Water for Injection (WFI) Tank Vents
  • Oxygen-rich Fermented Air
