RF-UF-PT
RF-UF-PT ePTFE Membrane Filter
Hydrophobic ePTFE for aggressive liquids & sterile gas
Overview
The RF-UF-PT uses a highly hydrophobic expanded PTFE (ePTFE) membrane — recognized as the world-leading gas sterilizing hydrophobic membrane. Exceptionally high gas flow rates at low differential pressures. Validated for bacterial removal (LRV >7) per HIMA/ASTM F838-05 in liquids. Wide chemical compatibility with high thermal stability for the most demanding microfiltration applications.
