TefloFlow HT Filter Cartridges
Hydrophobic PTFE / Hydrophilic PTFE Membrane · Sterilizing Grade

TefloFlow® HT Filter Cartridges are composed of a hydrophilic PTFE membrane, polyphenylsulfide (PPS) support layers, and oxidation stabilized polypropylene hardware.  This filter is recommended for sterile filtration of liquids in critical high temperature applications or filtration of ozonized water.  The cartridge is also available with hydrophobic PTFE media upon request


Features and Benefits

  • Oxidation-resistant materials provide longer service life in critical air and vent applications
  • Exceptionally high flow rates at low pressure drops
  • Robust construction offers outstanding stability during steam sterilization
  • Wide chemical compatibility
  • Complies with Food Contact Regulations: FDA 21CFR177-182 and 1935/2004 EC
