Product Details

SLF-T - Hydrophobic PTFE Membrane Cartridge

Brand OptiFluor

Media: Gases

Micron Ratings: 0.2 µm

Filter Type: Pleated Membrane

Masterfilter SLF-T 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 Benefits

0.2 µm rated
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
