Description
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 **0°C 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 1.2Dã€2D 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.
Application
Because of its favourable price/quality ratio, polyester is the
most common fibre used in filter media.
