Easy to clean polyester felt dust bag introduction:

The easy to clean polyester felt dust removal bag is made of high-quality polyester fine yarn with a diameter of 1-2.5D, woven with high-strength and low elongation yarn to enhance the base fabric, and reinforced by needle punching and post-processing technology. Polyester needle punched filter felt has the characteristics of high porosity, good breathability, moderate acid resistance, and alkalinity that are unique to ordinary felt filter cloth. In addition, it has moderate temperature resistance and can instantly reach 150 ℃. Therefore, this bag is one of the commonly used filter materials. The surface treatment method can be applied according to different requirements of working conditions, such as singeing, calendering, or coating.

Working principle of easy to clean polyester felt dust bag:

The surface smoothness of the easy to clean polyester felt dust removal bag has a significant impact on the dynamic operating resistance of the filter material. The initial resistance of the filter material is determined by the permeability of the filter material itself, and the resistance during operation is many times greater than the initial resistance. The running resistance depends on the smoothness of the surface of the polyester needle punched filter felt filter material, the cleaning effect, etc. The polyester needle punched filter felt filter material ensures the same filtration efficiency, and the higher the air permeability, the better, that is, the lower the resistance, because this can save a lot of energy. In dust collectors that use air flow back blowing for dust cleaning, when using air flow of the same pressure and air volume for dust cleaning, using fabric with high air permeability as the filter bag has better dust cleaning effect than using fabric with low air permeability.
