Three to twelve bags, 120 to 480 m³/h. More area at the same face velocity — longer runs, not just more flow.
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. Size 1 bags can be accommodated where the duty suits; Size 2 is our pick, and the four-bag Size 2 is the one we supply most.
| Bags | Inlet / outlet | Max flow | Filter area |
|---|---|---|---|
| 3 | DN80 | 120 m³/h | 1.5 m² |
| 4 Our pick | DN100 | 160 m³/h | 2.0 m² |
| 6 | DN150 | 240 m³/h | 3.0 m² |
| 8 | DN150 | 320 m³/h | 4.0 m² |
| 10 | DN200 | 400 m³/h | 5.0 m² |
| 12 | DN200 | 480 m³/h | 6.0 m² |
Max flow is the manufacturer’s maximum, not a rate to size against. Their working limits for a Size 2 bag are 30 m³/h for normal liquids and 20 m³/h at 5 µm and finer — so a twelve-bag housing is a 360 m³/h duty in practice, not 480. Tell us the fluid, the rating and the solids loading and we will size it properly.
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.
Need the cover open in twenty seconds instead of undoing a ring of bolts? That is the quick-open BF range. Cannot stop the process to change a bag at all? That is a duplex arrangement.
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 →
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.
