PTFE Membrane Filters

Polytetrafluoroethylene (PTFE) is a highly hydrophobic fluoropolymer. Filter membranes made using this material are ideal for filtering non-aqueous chemicals and solvents, purifying process air and gases, and protecting tank contents via tank vent filtration.

Media Grades

The PTFE filters from Critical Process Filtration are offered in Pharmaceutical, Biopharmaceutical, Electronics and Service Grades, so users can choose the membrane performance profile that best suits their needs.

Services

Critical Process Filtration partners with users to develop cost-effective filtration systems and perform application-specific tests for filter performance and safety. We provide complete documentation suitable for validation reviews by regulatory authorities. We also offer other Services to help you choose and verify your filter performance.
