Sterilizing-grade filters for the sterile filtration of gases

Hydrophobic  cartridge filters provide high flow  rate and minimal differential pressure. Cartridges are robust, strong, and resilient and are designed to withstand multiple steam-in-place cycles. Each  cartridge filter is integrity tested during the manufacturing process.
A full range of filtration areas is available to suit varying applications and a variety of connection options are offered for easy adaptation to existing housings.

Key Features
◇ Highly safe sterilization, ensuring 100% filter efficiency in humid environment during gas

filter, 0.2um filter rating in liquid, for gas filter, single layer: < Φ0.01μm; double layer: < 0.003μmΦ;

◇ Strong hydrophobicity, passing water intrusion test, avoiding residues due to the integrity of solvent wetting test;

◇ Single- or double-layer; large filter area, small pressure difference, large throughput, long service life;

◇ Excellent chemical compatibility, endurable to acid, alkali, and organic solvent;

◇ Cartridge independently numbered, production batch traceable;

◇ Passing 100% integrity test, quality safe and reliable;

Typical Applications
◇ Pre-filtering gases of storage tanks, respirators, and ferment tanks sterilization;
◇ Sterilization of solvents such as esters, alcohols, acids, and alkalis particle filtering;
◇ Sterilization and filtering of compressed air or gases in medicine and food industries;
