Specifications

Polyester filter bags are the most versatile,most cost effective and most widely used filter medium for dust collection. And have good resistance to common acids, solvents and oxidizing agents.
Feature:
1.  By using high strength scrim, the strength of the felt is increased by a wide range
2. Selecting 1.2D-2D and 2.5D excellent polyester fibers to produce. So this products possess high porosity, good permeability and high effective dust collecting.
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 efficient.
5. Low operation resistance ,saving energy.
