NUOENWEI High-Temperature Fiberglass Duct | Flexible Industrial Ventilation Hose (-45℃ to 300℃ / 400℃ / 1200℃)
The NUOENWEI High-Temperature Fiberglass Duct represents the pinnacle of flexible air conveyance engineering. Manufactured with premium glass fiber fabric and a robust mechanical design, this duct is engineered to solve the most demanding industrial ventilation challenges. Unlike standard PVC or polyurethane hoses that fail under thermal stress or abrasion, the NUOENWEI duct features a triple-layer composite construction that provides exceptional thermal insulation while maintaining superior flexibility.
Whether you are directing heated air for construction site thawing, extracting chemical fumes, or connecting to a portable diesel heater, the external galvanized steel spring helix ensures the hose can be dragged across rough concrete floors without wearing through the jacket. With a standard temperature resistance of -45℃ to 300℃ and optional upgrades for continuous use up to 1200℃, this duct is the professional’s choice for safety, durability, and performance.
Why Choose NUOENWEI Industrial Hose?
As a specialized manufacturer of thermal ventilation solutions, NUOENWEI focuses on durability and safety. Our fiberglass ducts are manufactured under strict quality control to ensure consistent wall thickness, reliable bonding of the insulation layer, and precise steel helix spacing. When you choose NUOENWEI, you are selecting a duct that will last longer, drag better, and handle heat more safely than standard commodity ducting.

Product Advantages
- Extreme Thermal Range: Standard configuration operates continuously from -45°C to 300°C.
- Custom Options Available: Upgraded insulation for 400°C or specialized ceramic fiber construction for intermittent spikes up to 1200°C.
- Superior Abrasion & Drag Resistance: The external galvanized steel spiral armor protects the fabric jacket. The hose can be dragged across job site floors, gravel, or scaffolding without tearing the internal layers.
- Vibration Dampening & Flexibility: Engineered to absorb mechanical vibration from engines and compressors. The hose can be bent to a tight radius without kinking or collapsing.
- Chemical & Flame Resistance: The fiberglass substrate is naturally flame retardant (meets most industrial fire codes) and exhibits excellent resistance to oils, solvents, and acidic exhaust gases.
- Crush & Weight Bearing: The robust steel helix provides structural integrity, allowing the hose to support its own weight across long spans and resist crushing under heavy foot traffic.
- Customizable Aesthetics & Sizing: Stocked in Gray, Yellow, Black, and Blue. Custom colors and exact diameter/length configurations are available for OEM volume orders.
Application Scenario
1. Temporary Heating & Construction Climate Control
Specifically designed for connection to portable gas or oil-fired indirect air heaters. Use this duct to:
- Deliver warm air to building interiors during winter construction.
- Thaw frozen ground for excavation projects.
- Safely exhaust fumes from heater combustion chambers away from occupied spaces.
2. Industrial Process Conveyance
- Plastics Industry: Conveying hot air for granulate dryers and hopper loaders.
- Printing & Packaging: Exhausting hot, solvent-laden air from high-speed printing presses and drying ovens.
3. Aggressive Fume & Dust Extraction
- Chemical Plants: Extraction of steam, acid fumes, and airborne chemical particulates.
- Welding & Foundries: Removal of high-temperature dust, fibers, and abrasive solid particles.
