Detailed Product Description

Polyester needle felt with PTFE membrane
Polyester needle felt adopt nonwoven needle punch workmanship, after heat setting or other finish treatment, widely used for dust collector, fume removal for many industries. Polyester needle felt with a good air permeability, after heat setting will keep a smooth surface, free from deformation, easy cake release.
After membrane treatment will equip the ability of smooth surface, water oil repelled, easy cake release, improve the filter efficiency, never block, save energy, prolong the using life.
The relative parameters: (1).air permeability: 2~5 m3/m2.min@200Pa
 (2). Dynamic resistance:<180Pa. (3).filer efficiency: >99.99%. (4).membrane fastness: >0.03MPa. (5).filter air speed: <1.5m/S (6).service temperature:<150C.
Application: For air filtration in normal temperature, widely used in steel mills, cement plant (collect the dust especial for the dry-process rotary kilns for cement mills), chemical plant, foundry works, flour mills, wood processing plant,etc.
