DFX-ANT™ Antistatic Dust Filter Bags

DFX-ANT™ Antistatic Dust Filter Bags are engineered for controlled electrostatic dissipation in industrial dust collection systems handling combustible, fine or static sensitive particulates. Manufactured using conductive needlefelt media, antistatic fibres and conductive stitching, the bags provide a continuous pathway for charge dissipation when correctly installed, grounded and integrated into a properly designed dust collection system.

Designed for use in applications subject to combustible dust risk assessments, including ATEX Zone 21 and Zone 22 environments, DFX-ANT™ supports stable airflow, consistent particulate retention and reliable dust cake release under continuous operating conditions. Media construction, surface treatment and bag configuration can be selected according to the dust characteristics, operating temperature, moisture exposure, chemical conditions, cleaning system and required electrical resistance.

DFX-ANT™ is suitable for chemical processing, food and ingredient handling, pharmaceutical manufacturing, plastics production, biomass operations, powder transfer and other processes where effective dust control and static dissipation are essential. Antistatic performance must be supported by correct grounding, bonding, system design and site specific safety controls.
