Explosion Proof Flexible Ducting - Conductive, Fire Resistant Ventilation Hose | NUOENWEI
Our conductive flexible ducting eliminates static ignition risks in explosive atmospheres. Engineered with steel-reinforced PVC, dual grounding wires, and flame-retardant materials (UL94 V-0 equivalent), it ensures safe ventilation of flammable dust, gases, and fumes. Deploys in seconds with integrated handling rings.
Defusing Danger: The Ultimate Static-Dissipating Ventilation Solution
- In explosive environments, standard ducting can become a lethal conductor. Our anti-static explosion proof ducting is engineered from core to connector:
- Conductive Core: Steel wire helix wrapped in static-dissipating PVC (surface resistance: 2×10³ Ω) channels charges safely.
- Dual Grounding: Integrated tin-plated copper braids at both ends ensure secure earth bonding.
- Instant Deployment: 1-meter spaced handling rings enable rapid, one-person installation.

Product Advantages
Conductive explosion-proof construction
- Characteristics: Pipe body embedded in high-carbon spring steel + conductive PVC layer, pipe shaft resistance of only 2 × 10³Ω
- Advantage: Active conductive static electricity, eliminating the risk of spark ignition in flammable dust/gas environments, complying with ATEX/IECEx explosion-proof standards.
Dual channel grounding system
- Features: Integrated tin braided copper wire at both ends, with multiple conductive connections to the steel wire skeleton.
- Advantage: 3-second quick grounding ensures safe release of mechanical friction charges to earth.
Class B Flame Retardant Armor
- Features: 0.4-0.65mm thick flame retardant PVC coating (ASTM E84 certified)
- Advantage: Self-extinguishing in case of fire, 70% reduction in fire spread rate in confined scenarios such as tunnels/mines, etc.
