TefloGas Filter Cartridges

Hydrophobic PTFE Membrane  ·  Sterile Gas Filter

TefloGas Filter Cartridges are composed of a hydrophobic PTFE membrane and a thick thermal-resistance polypropylene core. They are characterized by a high filtration area and non-metallic ion release and are easy to clean when compared to filters with a stainless steel core. As a result, they are highly recommended for air and gas sterile filtration of biological liquids and fermentation and pharmaceutical industries.

Features and Benefits

  • Inherently hydrophobic
  • Exceptionally high flow rates with low pressure drops

Quality Standards

  • Integrity Test correlates to ASTM F838-05 Bacterial Challenge Test (BCT)
  • Each filter is individually Integrity Tested (including Water Intrusion Test) 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

  • Aseptic Packaging
  • Compressed Air and Nitrogen Gas Sterilization
  • Corrosive Gases Sterilization
  • Vent Filtration
