Our filter bags are designed based on actual site conditions, not generic catalog assumptions. We help you select the right media to balance filtration efficiency, pressure drop, and service life.
In applications such as coal dust, flour, aluminum powder, chemical powders, and organic dust, static electricity is generated during filtration and pulse cleaning.If the charge cannot dissipate, spark discharge may occur, leading to fire or explosion risks.
Our Solution-Anti-static filter bags
Prevent sparks. Prevent explosions. Protect your baghouse operation.
Conductive fibers or stainless steel conductive materials are mixed into the chemical fibers used to produce needle felt to produce antistatic needle felt with excellent antistatic properties. The results of comparing antistatic dust filter bags with ordinary dust filter bags in terms of physical properties, charge and dust removal efficiency have confirmed the superiority of antistatic dust filter bags.
- Conductive fibers are not affected by the environment.
- When the fabric is charged, it discharges through its own weak corona and leaks to the ground.
- When weaving, long filaments are used for warp yarns and short filaments are used for weft yarns.

Typical Applications
Coal-fired boilers
Flour & grain processing
Chemical powders
Aluminum & metal powder
Adding an ePTFE membrane to an aramid filter bag allows the membrane to act as the filter cake. Dust stays on the surface of the membrane and does not get entrained into the fibers of the filter bag, which lengthens the life of your filter bag. It also reduces wear and tear, lower maintenance costs, and energy costs due to easy dust cake release during the cleaning cycle.
