Product Introduction

The multi bag filter housing consists of a filter housing, multiple fixed filter baskets, and multiple filter bags for high-flow fluid filtration at flow rates up to 2400 GPM.

We offer both standard and custom multi bag filter housings. Standard multi bag filters are available from 2 to 24 bags, while custom class bag filters can accommodate up to 40 bags.

For filters with several filter bags, a handwheel and a swivel arm with standard bearings are provided, making it easy to open and operate.
For filters with 12 or more filter bags, cylinders or hydraulic auxiliary devices can be selected, because this can make the filter open and close, only one operator is needed, and the auxiliary devices include pressure relief valves, positioning pins, etc., which effectively ensure the safe operation of the equipment.

benefits

Easy Maintenance & Safety

Replace filter bags seamlessly when pressure reaches 0.14–0.17 MPa (prevents system overload).
Integrated pressure relief valves and ergonomic design (handwheel/swivel arm for ≤12 bags; hydraulic/pneumatic assist for ≥12 bags) reduce manual effort.
Replace deformed gaskets immediately to avoid leaks.

Customizable Configurations

Add auxiliary devices like positioning pins or automated cylinders for single-operator access.
Tailor inlet/outlet orientations (side or bottom discharge) to fit your pipeline layout.

Built to Last

Corrosion-resistant stainless steel or coated carbon steel housings withstand harsh conditions.
Reinforced filter baskets secure bags during high-pressure cycles.

Applications

Chemical Processing

Remove catalyst residues or impurities from solvents.

Water Treatment

Filter sediments, rust, or microplastics in municipal/industrial water.

Oil & Gas

Protect pumps and pipelines from abrasive particles.

About maintenance

The filter bag needs to be replaced when the impurities on the filter bag build up into a filter cake and the differential pressure reaches 0.14-0.17 MPa.

When replacing the filter bag, the filtration system must be closed for a period of time and the pressure relief valve and filter cap must be opened.

As bag filters are frequently used, trapping a large quantity of impurities, as a result, regular inspection, maintenance and repair are required even the differential pressure is small.

If the gasket is deformed, replace with a new one immediately.
