FSSB Multi Bag Filter Housings are used in high flow applications and can operate under high temperature and pressure.

These bag filter housings are constructed of either stainless steel or carbon steel.

Many clients use these multi-bag filter housings in water and oil applications.

FSSB bag filter housings are usually in-stock with up to 12 bags per vessel, which will get you higher flow rates and less downtime for bag changes.

These FSSB series filter vessels are rated 150 psig working pressure and use industry standard #2 filter bags which we always have on hand and ready to ship to you.

We’re waiting for your call, 248-919-6119, and would love to help you get the perfect bag filter system.
