Products / Bag Filter Housing
Factory-direct stainless steel bag filter housings from Shandong Ningchuan — single & multi-bag vessels in SS304/316L, #1/#2 bag sizes, 150 PSI design pressure, sanitary finish.
Shandong Ningchuan Water Treatment Equipment Co., Ltd. is a direct manufacturer of stainless steel bag filter housings, based in Linyi, Shandong, China. Every vessel is cut, welded, polished and pressure-tested in our own workshop — so you buy at factory price, with full control over material certificates and lead time.
A bag filter housing (also called a bag filter vessel) holds a fabric filter bag that removes solid particles from liquids. Compared with cartridge filters, bag filter housings handle higher flow rates and larger dirt loads at lower operating cost, because only the bag is replaced — the vessel itself is reused for years.
Our standard range covers single-bag and multi-bag (2 to 8 bags) vessels in SS304, SS316 and SS316L for water treatment, chemical processing, food & beverage, coatings and oil filtration. Custom sizes, nozzle layouts, jackets and surface finishes are available on request.

Single-bag, multi-bag, jacketed and special designs
Compact vessel for low to medium flow — ideal for small process lines, pilot plants and point-of-use filtration.
2 to 8 bags working in parallel. Handles very high flow in a single vessel, cutting footprint, piping and maintenance.
Steam or water jacket keeps viscous liquids flowing and prevents crystallisation in coatings, resins and syrups.
Magnetic bag filter housings to capture ferrous particles, plus clamp-type and top-entry designs.

Common questions from overseas buyers about bag filter housing manufacturer — click a question to expand.
We are a manufacturer. Our factory is in Linyi City, Shandong Province, China, where we cut, weld, polish and pressure-test stainless steel filter housings and tanks in-house. You are welcome to visit, or to ask us for a video factory tour.
A single bag housing holds one filter bag and suits low to medium flow — it is compact and economical. A multi-bag housing holds 2 to 8 bags in parallel, so it handles much higher flow rates and dirt loads with fewer change-outs. Multi-bag vessels are normally chosen when flow exceeds roughly 60–80 m³/h, or when continuous operation is required.
SS304 for general water and mildly corrosive liquids; SS316 / SS316L for aggressive chemicals and for food or pharmaceutical duty. Carbon steel is available on request. Seals can be EPDM, NBR, Viton or silicone depending on the liquid and the operating temperature.
Yes. As a manufacturer we build to your drawing: bag quantity, vessel diameter and height, nozzle size and position, connection standard (ANSI / DIN / JIS), jacket, trolley, and mirror polish or sandblast finish. OEM and ODM orders with your own logo and packaging are also welcome.
Standard models are usually ready in 7–15 working days; fully customised vessels take 20–30 working days. We accept trial orders from 1 piece, with tiered pricing for larger quantities. Send us your flow rate, liquid and filtration rating for an exact quote.
Confirm four things: (1) flow rate in m³/h, (2) the liquid and its operating temperature, (3) required filtration rating in microns, and (4) connection standard and available space. With those details we will recommend the bag size, number of bags and material. If you are unsure, send us your working conditions — our engineers will size it for you free of charge.
