304 Sanitary Threaded Tank Breather Filter Housing with 226 Cartridge

The 304 Sanitary Breather Filter Housing is designed for clean air exchange and vent filtration in sanitary tanks, vessels and process systems.

During filling, emptying or temperature changes, storage tanks may need to exchange air with the surrounding environment. This breather filter housing allows air to pass through a replaceable filter cartridge while helping reduce the entry of dust and airborne contaminants.

The housing is manufactured from 304 stainless steel and features a 226 cartridge interface, making it suitable for applications where hygienic design, easy maintenance and reliable air filtration are required.

Multiple connection sizes from DN10 to DN65 are available to meet different installation requirements.

How Does a Breather Filter Work?

A storage tank needs to exchange air when the internal liquid level or temperature changes.

When the tank needs to draw air in, outside air passes through the breather filter cartridge before entering the tank.

When the internal pressure increases, air can leave the tank through the same filtered pathway.

The filter cartridge helps reduce the entry of dust and other airborne particles, helping maintain a cleaner internal environment.

This makes the breather filter suitable for tanks and vessels where clean air exchange and contamination control are important.
