Description
304 SS Sanitary Single-Cartridge Tank Breather Filter
This 304 stainless steel sanitary single-cartridge tank breather filter is designed for filtered air intake and exhaust on fermenters, storage tanks, and other hygienic process vessels. It allows the vessel to exchange air during filling, emptying, fermentation, and temperature changes while helping reduce the risk of airborne contamination entering the tank.
The housing uses a sanitary Tri-Clamp connection and polished stainless steel construction. The replaceable filter cartridge is mounted on an internal perforated base structure that provides the air-flow path through the filter element. The same housing path supports both incoming and outgoing air, making the unit suitable for hygienic tank breathing and sterile air exchange.
