What is a membrane polyester filter bag?

The filter bag is made from the membrane covered filter cloth which undergoes form membrane post-treatment procedure during the production. Other filter materials can also be treated with film coating for example PP, Aramid, P84, PPS, Fiberglass, and PTFE etc. The most commonly used filter bag in normal conditions is polyester film coated filter bag.

The polyester filter bag is made of 100% polyester raw material. According to the characteristics of working conditions and usage requirements .Different production equipment and manufacturing procedures are adopted. Mix polyester fibers with different denier numbers through needle punching. Afterwards it undergoes singeing, heat setting, and rolling followed by post-treatment with film coating .This manufacturing procedure produces a coated polyester felt that has high filtration performance and excellent quality. The polyester felt is then sewed to form a membrane coated polyester filter bag.

What is the special production processes for membrane polyester filter bags?

The polyester filter bag is made of polyester needle felt. The most conventional polyester needle felt on the market only needs to be needle punched, singed, heat set, and rolled before use. However, in some complex working conditions with high filtration or any other specific requirements. Special production procedures are be used to increase the performance of filter bags.

Filter bags can be treated with singeing, calendaring, water and oil repellent coating, PTFE impregnation and lamination as per customers demand and configuration.

What are the advantages of membrane polyester filter bags?

The biggest advantage of coated polyester felt is that it enhances filtration efficiency and reduces surface adhesion on the filter bag. Therefore, increasing the filter bag life compared to a conventional filter cloth.

In comparison with ordinary filter materials the advantages of membrane coated filter bags are as following:

The membrane pore size is between 0.23um, and the filtration efficiency can reach around 99.99%, achieving almost zero emissions. After cleaning the filter it’s porosity remains unchanged and the dust collection efficiency remains high. The membrane coated filter material also has great chemical stability, heat resistance and chemical corrosion resistance.

The membrane coated dust collection filter bag has a strong and soft fiber structure, compounded with a strong substrate, which has sufficient mechanical strength. In addition, it has excellent ash removal ability, making the cleaning process very simple and easy. Under low and stable pressure it has a long service life.

Characteristics of coated polyester filter bags:

High breathing ability

Low resistance

Great filtration efficiency

Large dust capacity

High dust stripping rate makes it the best filter material for sterilization and dust collection.
