1,excellent anti-abrasion 2, longer using-life 3, high efficency of cleaning. 4,good anti-acid and mild anti-alkali.

Detailed Product Description

Polyester needle felt bag is the most widely used for pulse jet

application. Recommended operating temperature is 135°C maximum. In the presence of a saturated vapor, the fibers will hydrolyze, weakening the fabric. It provides good resistance to most oxidizing agents, mineral acids, and most organic solvents except high concentrations of sulfuric, carbolic and nitric acids. It resists weak alkalis.  With efficient filtration and good energy absorption characteristics. The bag is widely used in chemical,metallurgical, food industry and other applications.
