DFX™ Series – Dust Filtration Excellence

DFX-ANT™ Antistatic Dust Filter Bags

DFX-ANT™ Antistatic Dust Filter Bags are engineered for safe and reliable dust filtration in explosive or static-prone industrial environments. Manufactured using conductive felts and antistatic stitching, these bags support the controlled dissipation of electrostatic charge, reducing ignition risk in applications involving combustible dust.

Suitable for ATEX Zone 21/22 and other hazardous areas, DFX-ANT™ provides stable filtration performance where static control, material durability, and filtration consistency are critical for operational safety. This antistatic filter bag media delivers dependable service across industries such as chemical processing, food production, pharmaceutical dust collection, plastics, and biomass operations.

Technical Specifications
  • Material: Conductive needlefelt with carbon, copper, or stainless-steel fibres integrated into the media
