The dust collector filter bag's primary function is to filter dust, and the purpose of opening filter holes is to minimize the resistance from dust. The selected PPS dust collector filter bag adopts the fabric medium's structure. Therefore, pollutants will be blocked when passing through holes. Polyester dust collector filter bag uses a filter membrane to purify air pollutants. Its principle is to use coarse filter cardboard for filtration and then finish the filtration of all pollutants by fine filtration.

The factors affecting the working effect of dust collector filter bags include selecting the dust collection medium, etc. Only in this way can it be protected from damage, and the polyester dust collector filter bag can be prevented from being damaged and brittle. The products produced by dust collector filter bag manufacturers need to meet specific needs, such as temperature resistance, corrosion resistance, etc.

These factors will affect the structure of the dust collector filter bag and the method of dust collection. When selecting the raw materials for making the cloth bag, attention should be paid to the work's temperature and purified flue gas, mainly the fire prevention materials, etc. The use of polyethylene filter material is more suitable for dust collector filter bags, etc. In the range of temperature change, the product material should be changed according to the pollutants to be filtered to improve the purification efficiency.
