Introduction
Referred to as Anti-Static Polyester Dust Filter Bag and Conductive Fiber Explosives Filter Bag, this specialized filtration solution is designed for explosive and combustible dust environments. Constructed from 100% conductive polyester staple fiber with integrated carbon filaments, the bag dissipates static electricity to prevent ignition of explosive dust clouds, critical for compliance with ATEX and NFPA standards.
Unlike standard filter bags, this anti-static variant maintains a surface resistance of 10³ to 10⁸ Ω·cm, ensuring safe static charge dissipation while providing high-efficiency dust collection. The conductive network cross the fabric, eliminating charge buildup that could spark explosions in facilities handling explosives, pyrotechnics, and combustible powders.
Features
Safety and Filtration Performance
Anti-Static Properties: Continuous conductive path through the fabric ensures surface resistance remains within 10³–10⁸ Ω·cm, meeting OSHA and NFPA 652 requirements.
Filtration Efficiency: M13 rating captures 99% of particles down to 13μm, including explosive dusts like gunpowder, ammonium nitrate, and metal powders.
Material Construction: Blend of conductive and standard polyester fibers in stripe or square patterns, balancing conductivity and mechanical strength.
Durability: Abrasion-resistant felt with tensile strength >1600N/5cm, suitable for high-velocity dust streams in explosive processing.
Operational Safety
Spark Resistance: Conductive threads dissipate static charges before reaching ignition thresholds (<0.1mj for most explosive dusts).
Chemical Compatibility: Resists degradation from explosives processing chemicals, including nitrates and peroxides.
Temperature Range: Operates safely at -40°C to 135°C (-40°F to 275°F), compatible with most explosives manufacturing environments.
Application Cases
This anti-static filter bag is critical in explosive and combustible dust industries:
Explosives Manufacturing: Filters dust from propellant and detonator production, preventing ignition sources in Class II, Division 1 hazardous locations.
Pyrotechnics Production: Controls aluminum and sulfur dust in fireworks manufacturing, complying with ATEX 137 directives.
Mining Explosives: Manages dust from emulsion explosive mixing, protecting workers and preventing accidental detonation.
Chemical Powder Handling: Captures combustible pharmaceutical and fine chemical powders in API manufacturing facilities.
Product Advantages
The filter bag offers unique safety and performance benefits:
Explosion Prevention: Eliminates static discharge as an ignition source, reducing insurance premiums by up to 30% in hazardous locations.
Regulatory Compliance: Meets NFPA 654, ATEX, and OSHA 29 CFR 1910.178 standards for combustible dust handling.
Long Service Life: 8–12 month lifespan in continuous operation, outperforming coated anti-static bags by 50%.
Cost-Effective Safety: 20–25% lower cost than PTFE anti-static alternatives while maintaining equivalent safety performance.
Quality
Use the special thread for dust bags. During the edge sealing process, there will be no issues such as detachment or broken threads.
Select high-quality materials to increase the product's service life.
