DWD group Anti-static Polyester Needle Punched Filter Bag blends conductive fiber and polyester fiber to form a highly fluffy three-dimensional filtration media. Loose fibrous texture, ultra high air permeability, excellent effectively capture fine particles and colloidal particles, and not easy to blocking.

DWD Non-woven technology of antistatic filter cloth is world-class, we can produce both mixed conducting fiber needled felt and conductive yarn in the warp of needle felt base cloth.

High strength fiber avoids the damage caused by increasing pressure during the filtration process.

The electrostatic conductive filter can transmit the total electricity generated in the production process, and the high temperature heat treatment is applied on the surface of the needlefelt to avoids the occurrence of fiber removal, ensures the filtration efficiency.

Application:

Widly use in dust, chemical dust, pulverized coal dust and other industries, such as electrostatic discharge explode, it is an ideal choice for explosion dust collection at present.
