NUOENWEI Explosive Proof Duct
The NUOENWEI Explosive Proof Duct is a state-of-the-art flexible ventilation solution that prioritizes safety and performance. Constructed from B1-grade flame-retardant polyvinyl chloride (PVC) coated with abrasion-resistant strips and reinforced with high-carbon spring steel, this duct offers exceptional strength and resistance to acids, tearing, corrosion, cold, heat, water, and flame. Its inherent conductivity ensures that static electricity generated during operation is safely channeled away, preventing sparks that could ignite explosive atmospheres.

Product Advantages
- Flame-Retardant & Durable Material: Made from B1-grade flame-retardant PVC with abrasion-resistant coating, the duct withstands harsh conditions including acids, tearing, corrosion, extreme temperatures (-15°C to +80°C), and water.
- Inherent Conductivity: The hose body is conductive, with a resistance of 2×10³ ohms. Two tin-plated copper braids are integrated with the steel helix for multiple grounding paths, effectively discharging static electricity to safe areas.
- Easy Grounding: The copper braids simplify grounding connections, ensuring compliance with safety regulations in explosive environments.
- Integrated Lifting Loops: Handles are spaced approximately every meter, enabling easy positioning and secure fastening.
- Flexible & Lightweight: The duct can be freely bent, extended, and connected. Its lightweight design facilitates portability and quick setup.
- Environmentally Safe: Non-toxic, odorless, dust-free, and fiber-free material. Seamless construction prevents air leakage and minimizes pressure loss.
- Customizable Sizes: Available in diameters from 4” to 59” (100mm–1500mm) and standard lengths of 5m or 10m. Other lengths available upon request.
- Wide Temperature Range: Standard operation from -15°C to +80°C; optional versions for extreme cold or heat.
- Easy Connection: Compatible with fans and blowers using belts or PP ropes. The duct can be extended indefinitely by connecting multiple sections.
Application Scenario
- The NUOENWEI Explosive Proof Duct is ideal for a variety of industries and scenarios where explosive atmospheres or static electricity are concerns:
- Tunnels & Underground Mining: Ventilation during excavation to remove dust, fumes, and provide fresh air.
- Shipbuilding & Shipyards: Exhaust ventilation in confined spaces where welding, cutting, or painting occurs.
- Chemical Plants & Laboratories: Removal of hazardous fumes and dust while preventing static ignition.
- Firefighting & Smoke Extraction: Emergency ventilation in buildings or industrial sites.
- Municipal Pipeline Projects: Air supply or exhaust during maintenance or construction.
- Data Centers & Machine Rooms: Cooling air circulation with anti-static protection.

Frequently Asked Questions
1
What makes the NUOENWEI Explosive Proof Duct explosion-proof?
The duct is made from inherently conductive materials (fabric resistance 2×10³ ohms) and includes two tin-plated copper braids that are mechanically connected to the steel helix. This creates multiple paths to ground static electricity, preventing sparks that could ignite flammable atmospheres.
2
How do I ground the duct?
The two copper braids at each end of the duct can be connected to a grounding point using standard grounding clamps or wires. Ensure a proper electrical connection to earth for effective static dissipation.
3
What temperatures can the duct withstand?
The standard version operates between -15°C and +80°C. For extreme environments, we offer optional cold-resistant or high-temperature versions. Please contact us for specific requirements.
4
Can the duct be used with portable fans?
Yes, the NUOENWEI Explosive Proof Duct can be easily connected to portable explosion-proof fans using belts, ropes, or clamps. The lightweight design makes it ideal for mobile ventilation setups.
5
What sizes are available?
We offer diameters from 4” to 59” (100mm–1500mm) and standard lengths of 5m or 10m. Custom lengths and diameters can be manufactured upon request.
6
Can I connect multiple ducts together?
Absolutely. The ducts can be joined end-to-end using compatible connectors or straps to achieve any desired length.
