NUOENWEI Flexible Pipe for Exhaust – PVC Negative Pressure Hose with Steel Wire Spiral (Custom Sizes up to 1500mm)

• High-quality PVC material – Flame-retardant and self-extinguishing, which enhances workplace safety.
  
• Steel wire spiral reinforcement – Prevents pipe collapse under strong negative pressure and maintains a round cross-section.
  
• Rubber strip covering each steel wire – Provides superior abrasion resistance so the wires do not cut through the hose or wear out quickly.
  
• Standard wire spacing of 6 cm – Offers an optimal balance of flexibility and crush resistance, with custom spacing available.
  
• Wide diameter range from 100 mm to 1500 mm – One solution works for small fume extractors up to large-scale industrial exhaust systems.
  
• Lengths of 5 m or 10 m – Reduces the need for couplings and simplifies installation, with custom lengths available.
  
• Corrosion-resistant construction – Makes the pipe compatible with mild chemical fumes, moist air, and acidic exhaust gases.
  
• Designed specifically for negative pressure – Ideal for suction-side applications such as fans, blowers, and dust collectors.
  
• Lightweight and flexible – Easy to route around obstacles, suspend from overhead supports, or connect to moving equipment.

The NUOENWEI flexible pipe for exhaust is suited to a wide variety of industrial, commercial, and agricultural environments:

• Industrial exhaust ventilation – Removing welding fumes, grinding dust, or chemical vapors from workstations.
• Dust collection systems – Connecting woodworking machinery (saws, planers, sanders) to central dust collectors.
• Engine exhaust extraction – Vehicle repair shops, bus depots, and test cells where diesel or gasoline fumes must be evacuated.
• Negative pressure pneumatic conveying – Moving light materials such as sawdust, textile fibers, or plastic granules.
• HVAC fresh air / return air ducts – Using as a flexible connector between rigid ductwork and air handlers.
• Marine & tunnel ventilation – Corrosion-resistant performance in salty or humid environments.
• Agricultural drying – Moving heated air for grain or hay drying systems.
• Portable fume extractors – Lightweight enough for mobile exhaust removal units.
