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.
