Explosive Proof Duct - Conductive Flexible Ventilation Hose with Grounding Wire | ATEX/IECEx Certified
Our explosive proof conductive duct is engineered for extreme safety. Featuring a steel-reinforced PVC body with dual-layer conductivity (2x10³Ω resistance), B1 flame retardancy, and integrated grounding copper wires, it eliminates static risks in explosive dust/gas zones. From mining tunnels to shipyards, ensure compliance and worker safety.
Why This Duct?
Why This Duct?
Unlike standard ducts, our explosion-proof design integrates:
Dual-Safety Grounding: Wires + conductive body = redundant static discharge.
Reinforced Longevity: 0.65mm thick PVC resists punctures in rocky tunnels.
ECO-Compliant: Zero fiber release, non-toxic, ROHS-compliant.
Universal Compatibility: Clamps fit any ventilator (axial/jet fans).
