TEFguard series
TEFguard® PTFE cartridge filters
Scalable hydrophobic PTFE cartridge configurations for compatible gas and vent filtration requirements.
Product overview
TEFguard cartridge filters combine a hydrophobic PTFE membrane with polypropylene support and structural components for compatible air, gas and vent-filtration duties. Selection should account for gas composition, moisture exposure, retention requirements, flow, differential pressure, temperature, housing and connection requirements.
