Bag Filter Housing – Efficient Liquid Filtration Equipment

The bag filter housing is a device that intercepts particulate impurities in gases or liquids with filter bags as the medium, widely used in the field of liquid purification. It features simple structure, high filtration efficiency, wide adaptability, and convenient operation and maintenance, and is commonly used in coarse filtration and pre-filtration stages in industries such as environmental protection, food, pharmaceuticals, and petrochemicals.

The side entry bag filter housing, top entry bag filter housing, and multi bag filter housing provided by Snowate can meet different working conditions and filtration needs.

Side Entry Bag Filter Housing

It is an economical single-bag filter housing that can be used with filter bags for some coarse filtration and pre-filtration processes.
Side entry structure is a economical and reasonable design which can effectively save space of the filter.
Pressure ring and spring ensure good seal between the filter and the filter bag.
With adjustable legs, the installation size can be adjusted according to the requirements of the particular spot.

Top Entry Bag Filter Housing

A single bag filter housing with the most reasonable structure, which can be used with filter bags for some coarse filtration and pre-filtration processes.
The design of side entry first and then top entry into the filter bag does not cause turbulence and does not reduce pressure because of the stable pressure. Also, this structure effectively protects the filter bag.
The top cover is fully pressed and sealed, and the sealing effect is better.
With adjustable legs, the installation size can be adjusted according to the requirements of the particular spot.

Multi Bag Filter Housing

Standard 1# bag or 2# bag, the standard model for 2–12 bags, and the maximum production customized to 24 bags can basically meet the requirements of various types of flow.
Large flow, long service life.
Compact design can reduce occupied space and the loss of liquid.
Side entry and bottom out ensure that liquid medium can be completely discharged; the tangential position outlet, discharging pollution thoroughly, is convenient to operate.
The unique three-point clamp device ensures good sealing and avoids liquid side leakage.
The filter housing can add a swing arm and the eyebolt or quick-open design, operating conveniently and economically.
