Bag Filter Housing

Engineered to safeguard process fluid purity, the bag filter housing fits standard filter bags to achieve expanded filtration area and outstanding dirt-holding capacity. A hold-down ring paired with a dedicated O-ring prevents fluid bypass, securely retaining particles and suspended impurities inside filter bags during operation.

A wide selection of body materials extends service life for diverse operating conditions. V-band and davit arm closure options enable rapid bag replacement to minimize maintenance downtime. A top-entry design is available for single-bag housings to reduce fluid turbulence under fluctuating operating pressure. Specific designs include linings for aggressive fluids at high temperatures, and thermal jackets for process fluids prone to solidification and crystallization.

Compact in footprint yet robust in construction, the housing delivers high filtration performance and extends routine maintenance intervals. Supporting a wide range of flow rates and micron ratings, it accommodates flexible pre-filtration and final filtration for fluid purification across water treatment, general manufacturing, chemical processing, and food & beverage sectors.
