SLF-T - Hydrophobic Polytetrafluoroethylene (PTFE) Membrane Cartridge Filter
Masterfilter SLF-T series filter cartridges manufactured with permanently hydrophobic PTFE membranes are designed for sterile filtration of air and gas. Due to their permanent hydrophobicity, SLF-T cartridges offer high process security, with high volume gas streams and can withstand high differential pressures and stringent in-line steam sterilisations.
Features
- 0.2 µm rated (0.01 µm for gases)
- Pleated surface provides excellent flow rate and long service life
- Permanently hydrophobic PTFE for maximum security with wet and dry gas
- PTFE offers compatibility with most chemicals
- Suitable for all integrity test procedure incl. WIT
