Anti-Static Filter Bags for Combustible Dust Collection
Anti-Static Filter Bags
Prevent sparks. Prevent explosions. Protect your baghouse operation.
Anti-Static Filter Bags are designed for baghouse dust collection systems handling combustible, explosive or static-sensitive dust. In applications such as coal dust, flour, grain dust, aluminum powder, chemical powders and organic dust, static electricity may be generated during filtration and pulse-jet cleaning.
If the accumulated charge cannot be safely dissipated, static discharge may become an ignition source. Anti-Static Filter Bags use conductive fibers, stainless steel fibers or conductive yarn structures to help release static electricity and reduce spark discharge risks inside the dust collector.
- 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.

*The following data is a typical specification for anti-static polyester filter bags. Final parameters may vary depending on base fiber, scrim, weight, surface treatment, bag size and operating conditions.
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.

Technical FAQ
You should consider Anti-Static Filter Bags when your dust collector handles combustible, explosive or static-sensitive dust, such as coal dust, flour, grain dust, aluminum powder, chemical powders or organic dust.
Anti-Static Filter Bags can help reduce static discharge risks, but explosion prevention also depends on dust characteristics, grounding, system design, operating conditions and safety protection measures.
Polyester, aramid, P84, PTFE and other filter media can be customized with anti-static structures according to working temperature, dust type and chemical conditions.
Yes. Aokai can customize anti-static filter bag material, size, conductive structure, surface treatment, top and bottom design, and sewing method according to your dust collector and working conditions.
