What is the difference between a regular filter bag and a covered filter bag?

Ordinary filter bags and membrane covered filter bags are two different types of filter bags, with the main difference being their different filter materials.

Ordinary filter bags are usually made of materials such as cellulose, polyester, and polyester, which have good filtration performance but are prone to dust blockage, requiring frequent cleaning and replacement of the filter bag.

Membrane covered filter bags are processed on the basis of ordinary filter bags, usually by covering a layer of film on the surface of the filter bag. This layer of film can play a role in anti sticking, waterproofing, oil resistance, etc., thereby improving the service life of the filter bag and reducing the frequency of replacement and cleaning.

Therefore, compared to ordinary filter bags, membrane covered filter bags have better anti adhesion, corrosion resistance, and high temperature resistance, making them suitable for use in more complex and harsh working conditions.
