Non-woven Needle punched filter material is the fastest growing and most widely used filter material at present.
Needle felt filter material is a fibrous net with or without fabric on the two sides of the base cloth, which is made up of three dimensional interlaced fibers.Needle felt surface covered with a layer of PTFE micro porous membrane, influence can not only protect the filter from chemical corrosion and oil and water, but also can raise the accuracy of filtering bag.
Quality of the needle punched felt is stable and reliable, and the price is favorable. The needle felt produced in our factory can be accepted by the customers besides the industry standard model.

PRODUCT PERFORMANCE
Needle felt surface covered with a layer of PTFE microporous membrane, influence can not only protect the filter from chemical corrosion and oil and water, but also can raise the precision of filtration bag, surface filtration mechanism, coated needle felt the total filtration efficiency can reach above 99.9999%.
Needle punched felts are widely used to eliminate dust pollution, improve environment, recycle materials and so on.
The dust removal efficiency is high, and the fine dust with particle size greater than 0.3 microns can be captured, and the dust removal efficiency can reach more than 99%;
Flexible use, the amount of air can be processed from hundreds of cubic meters per hour to hundreds of thousands of cubic meters per hour, can be directly located in the room, near the machine tool small units, can also be made into a large dust chamber, that is, "bag room".
The structure is relatively simple, the operation is relatively stable, the initial investment is less (compared with electrostatic precipitator), and maintenance is convenient.
NEEDLE PUNCHED FELTS PURPOSE
Needle punched felts are the key part in the operation process of the bag filter, and usually the cylindrical filter bag hangs vertically in the dust collector.
