Bag Filter Housing: Quick-Opening Type

Main Features:

  1. Large processing capacity, small volume, and high dirt-holding capacity.
  2. Filter bags can be reused after cleaning, saving costs.
  3. Low probability of side leakage, ensuring high filtration quality.
  4. Continuous improvement in filter bag filtration precision, currently reaching around 5μm.
  5. Wide application range, flexible use, and various installation methods.
  6. Can withstand high working pressure, low filter pressure loss, and low operating costs.
  7. The quick-opening structure facilitates convenient and fast bag replacement based on the working principle and structure of the bag filter system.

Working Principle: The bag filter is installed at the front end of the inlet pipe of each matched valve to protect equipment on the pipeline from wear and blockage. When the medium enters the filter, the medium passes through the filter bag into the connected valve, while impurities are trapped inside the cylinder, preventing the valve from malfunctioning due to impurities getting stuck.

The bag filter is a pressure-type filtration device. The liquid flows into the filter through the side inlet pipe, entering the bag which is installed inside a reinforced mesh. The liquid permeates through the filter bag of the required precision level to obtain qualified filtrate, and impurity particles are captured by the filter bag. Bag replacement is convenient, and there is almost no material consumption during filtration.

Application Areas:

Applied in industries such as chemical, beer, water treatment, petroleum, biotechnology, food, coatings, etc.


  1. The bag filter needs to be cleaned after initial use to remove impurities accumulated on the filter bag during the system's initial operation.
  2. Regular inspection and cleaning are required during the use of the bag filter, with the frequency determined by the specific usage intensity. After the filter has been in operation for a period, impurities will accumulate inside the filter bag, leading to increased pressure and decreased flow rate, and should be promptly removed.
  3. Pay attention to the direction of water flow during installation.
