Stainless Steel Bag Filter for Industrial Liquid Solid Separation
Introduction:Stainless steel bag filter is a pressure-type liquid filtration device widely used in industrial liquid purification. Cooperated with water filter housing, high flow filter cartridge in the filtration system, it efficiently traps granular impurities in liquid streams, delivering large-flow and low-pressure-drop filtration for chemical, food, beverage and coating industries. It features compact structure and easy bag replacement, which greatly reduces daily maintenance workload.

Product Introduction
This stainless steel bag filter is a multi-purpose pressure filtration unit with innovative structure, small footprint and flexible operation. It belongs to a reliable water filter housing matched with filter bags, and can work together with high flow filter cartridge for multi-stage filtration. Liquid enters from the side inlet of the housing and flows into the filter bag supported by a metal mesh basket. The filtrate penetrates through the filter bag with target precision, while solid contaminants are captured inside the filter bag. The housing is manufactured from premium SS304 or SS316L stainless steel, with optional mirror polishing, matte or sandblasting surface treatment. It supports 1 to 10 filter bags, and connection options include clamp type, standard flange and swing flange. After filtration, users can replace or clean the filter bag quickly, and the cleaned filter bag can be reused to cut operating costs. No extra cleaning of the filter tank is required during bag replacement.
Working Principle
Under working pressure, raw liquid flows into the filter housing from the inlet and enters the filter bag supported by internal metal basket. Suspended particles, sediments and impurities are intercepted on the inner surface of the filter bag. Clean liquid passes through the filter bag and flows out from the outlet. When the pressure difference rises to the preset value, the operator opens the top cover and replaces or cleans the filter bag to restore filtration capacity.

FAQ
Q1: What is the difference between bag filter and security cartridge filter?
A: Bag filter has larger dirt holding capacity and higher flow rate, which is more suitable for liquid with high impurity content. Cartridge filter is preferred for higher precision polishing filtration.
Q2: Can filter bags be reused?
A: Yes. Most filter bags can be cleaned and reused if the trapped contaminants are easy to wash away.
Q3: What surface finishes are available for the stainless steel housing?
A: Mirror polishing, matte finish and sandblasting are optional.
Q4: What is the maximum working pressure of this bag filter?
A: The designed working pressure is no more than 0.6 MPa.
Q5: Is this bag filter suitable for corrosive liquid?
A: Choose SS316L housing and matched filter bag material to adapt to corrosive fluids.
