Multi-bag housings

Three to twelve bags, 120 to 480 m³/h. More area at the same face velocity — longer runs, not just more flow.

Three to twelve bags, 120 to 480 m³/h

A multi-bag housing is not simply a bigger filter. Putting more bags in parallel means more filter area at the same face velocity — so you get longer runs between changes rather than merely more flow. Every bag is Size 2, so the consumable does not change as you scale.

Design pressure 0.8 MPa, recommended working pressure 0.6 MPa. Housing in SS304, SS316L or carbon steel; seals in silicone, Viton, EPDM or PTFE. Polished or sandblast finish. Configurations from 2 bags upward available on request. Filter area shown for standard Size 2 bags at 0.5 m² each — roughly double with high-area bags.

Change bags on differential pressure. The manufacturer’s guidance is to change at 0.05–0.1 MPa differential across the housing. Fit gauges either side and work to the reading, not to a calendar — it is the single cheapest thing you can do to cut consumable spend.

Need the cover open in twenty seconds instead of undoing a ring of bolts? That is the quick-open BFR range. Cannot stop the process to change a bag at all? That is a duplex arrangement.

Price on application

Housings are quoted to duty — vessel size, material, seal compound, internal finish, connections and any certification requirement all move the price. Give us the fluid and the flow and you get a firm number, plus the expected bag change interval so you can budget the consumable too. Request a quote →

Tell us the duty, not the part number

Flow rate, fluid, temperature, particle size and how often you want to change bags. We size the housing and the bag around that and quote the pair, delivered and commissioned.
