This kind of product possess high porosity,good permeability,high effective dustcollecting long using-life etc. Common character as ordinary filter felt have. Besides, owing to its medial temperature resistance (can teach to 150 in short time), medial anti-acid and anti-alkali, especially its excellent anti-abrasion, polyester needle punched filter felt have the largest quantity of turnouts grams are from 350g/ to 800g/ , thickness are from 1mm to 3mm, all above products can be manufactured in our company. The surface treatment can be divided into singeing calendering or coated, etc, acording to different working conditions.
Note:1. the filter pecision from 1~200microns can be customized.
2.The weight (300~900 grams) and width (within 2.3 meters) can be customized!
