Bag filter

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. Bag filter is a new type of filter system. 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 replacing the filter bag.

Application water, oil, paint and other liquid purification and solid-liquid separation in machinery, metallurgy, chemical industry, textile, printing and dyeing, electroplating, medicine, food and other industries.
Filter media impurities in water, sediments and suspended solids, bacteria

Working principle

The bag filter is a pressure filter device, which mainly consists of a filter cylinder body, a filter cylinder cover, a quick-opening mechanism, a stainless steel filter bag reinforcing mesh and other main components. The filtrate flows into the filter bag from the side inlet pipe of the filter housing. The filter bag itself is installed in the reinforced mesh basket, and the liquid can obtain qualified filtrate by infiltrating the filter bag of the required fineness grade, and the impurity particles are intercepted by the filter bag. The machine is very convenient to replace the filter bag, and there is basically no material consumption for filtration. 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:
    Novel structure, small size, simple and flexible operation, energy saving, high efficiency, airtight work.


    Structural composition:

    It is mainly composed of main components such as filtration simplified, filter cartridge cover and quick-opening mechanism, stainless steel filter bag reinforcement net, etc.

  • The structural design is that the top cover and the filter cartridge are sealed and locked by four sets of rocker-type eye bolts.



    Classification: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.

  • The bag filter has many advantages such as reasonable structure, good sealing performance, strong circulation ability and easy operation.



    The probability of side leakage of the filter bag is small, the pressure loss is small, the operating cost is low, the filtration accuracy of the filter bag is continuously improved.

  • Paint, beer, vegetable oil, medicine, chemicals, petroleum products, etc.


    Widely used:

    paint, beer, vegetable oil, medicine, chemicals, petroleum products and other industrial water, sugar water, resin, industrial wastewater, etc.
