1, Fiber, efficient filtration, reduce emissions and running resistance.

• Filter bag manufacturers select fine fibers to increase the filtering area and reduce the filtering gap of filter materials, thus improving the filtering efficiency of filter materials, reducing the emission concentration and running resistance.
• The filter material is produced by imported equipment, and the performance of the produced filter material is stable.

 

2. Post-treatment of filter materials guided by customers' working conditions.
According to the change of dust characteristics, the needle felt filter material is treated with different surface or coated with protective layer to meet the needs of customers under different working conditions.

 

3. The filter bag shall be manufactured in strict accordance with the national standard of GB12625-90 to ensure the qualified rate of products leaving the factory.
