Single bag to twelve, 6 to 480 m³/h, bolted or open-in-twenty-seconds. In 304, 316L or carbon steel.
Every housing here does the same job — hold a bag and pass fluid through it. What separates them is how often you open it, how fast you need that to be, and whether the process can stop while you do.

One vessel, one bag, quick-opening cover. Four bag sizes. Where most duties start and many of them end.

V-shape clamp cover, open in twenty seconds from one standing position, interlocked so it cannot open under pressure.

More filter area at the same face velocity — longer runs between changes, not simply more flow. Bolted cover.

Two vessels behind one changeover valve. Turn the handle and change the offline bag with the process still running.
Under 40 m³/h and a single bag will do it. Above that you are into multi-bag — and remember flow figures are clean water, so derate for viscosity and solids.
Once a month, a bolted cover is fine. Once a shift, the quick-open cover pays for itself in labour inside a year.
If not, it is duplex — two vessels and a changeover valve. Nothing else lets you change a bag without stopping.
Three rapid-opening four-bag housings, drawing HLK4P2S-CC-F50, batch 202410017, manufactured December 2024. Hydrostatically tested to 1 MPa held for 30 minutes per the German AD pressure-vessel procedure (chapter 9, section 2.1), and passed leak test.
Where your installation requires registration or third-party inspection under Australian pressure-equipment requirements, tell us at enquiry stage so the documentation is specified before manufacture.
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.
