Polyester needle felt is the most versatile, most cost effective and most widely used filter medium for dust collection. It is strong, abrasion resistant, can work up to 150 and has good resistance to common acids, solvents and oxidising agents.
Feature:
1.By using high strength scrim, the strengh of the felt is increased by a wide range.
2. Selecting 1.2D2D and 2.5D excellent polyester fibers to produce.so this products possess high porosity,good permeability and high effective dustcollecting.
3.By using high lever fibers increase the ability of anti-acid,anti-alkali and the stability of water solution.
4.Smooth surface treatment,high filtration efficience.
5.low operation resistance,saving energy.
