The bag filter is a multi-purpose filtration equipment with novel structure, small volume, simple and flexible operation, energy saving, high efficiency, airtight work and strong applicability.
The inside of the bag filter is supported by a metal mesh basket. The liquid flows in from the inlet and flows out from the outlet after being filtered by the filter bag. The impurities are intercepted in the filter bag and can be used continuously after the filter bag is replaced.
Bag filter has the following categories: single bag filter, multi-bag filter, rocker bag filter, high-precision bag filter, etc., the filter filtration precision is in the range of 1-10 microns.

Bag filter is a pressure type filtering device, which mainly consists of filter cylinder, filter cylinder cover, stainless steel filter bag reinforcing mesh and other main components. The filtrate flows into the filter bag through the side inlet pipe of the filter shell. The filter bag itself is installed in the reinforcing mesh basket. The qualified filtrate can be obtained when the liquid permeates through the filter bag with the required fineness level, and the impurity particles are intercepted by the filter bag. It is very convenient to replace the filter bag. There is basically no material consumption for filtering.
Our bag filter housings are available in Stainless Steel, Carbon Steel, and Polypropylene (PP). Stainless Steel is ideal for high-purity water treatment, pharmaceutical applications, and food and beverage processing due to its corrosion resistance and durability. Carbon Steel is suitable for general industrial fluids and oil filtration, while Polypropylene is engineered specifically for harsh acid-base chemical solutions where metal housings would corrode.
The standard filtering precision for our standard bag filters ranges from 1 to 10 microns. However, our high-precision bag filter series can achieve an ultra-fine filtration rating of up to 0.5 μm. This allows them to effectively capture minute suspended solids, carbon particles, and micro-impurities in sensitive fields like pharmaceuticals and electronic cooling systems.
Selection depends entirely on your processing volume. Our multi-bag filter series scales from 2-bag models up to 24-bag systems. For lower-capacity needs, our DL-2P2S (2 bags) provides a flow rate of up to 70 m³/h. For heavy-duty industrial water treatment, our maximum DL-24P2S system (24 bags) can handle flow rates up to 840 m³/h. Always match your system's peak flow rate with the corresponding model's rated "Flow rate (m³/h)" to maintain a working pressure within 0.5 MPa.
The fluid enters through the side inlet and is forced down into the filter bag, which is structurally reinforced by a heavy-duty stainless steel internal mesh basket. This basket prevents the bag from stretching or bursting under pressure. Additionally, our design features a highly secure sealing mechanism that minimizes the side leakage rate of the filter bag, ensuring that all unfiltered liquid must pass through the media before exiting the outlet.
Depending on the material of the filter bag used and the nature of the trapped impurities (such as non-sticky particulates), the filter bags can often be cleaned and reused multiple times. Combined with a low operating pressure loss and a highly energy-efficient pressure design, this significantly lowers long-term consumable costs and reduces material waste during continuous industrial filtration.
