The NUOENWEI high temperature air duct is a state-of-the-art flexible hose designed for reliability and longevity under extreme conditions. Its unique three-layer construction – featuring a heat-resistant inner lining, an insulating middle layer, and a tough Oxford cloth outer cover – ensures excellent thermal efficiency and mechanical protection. The external steel helix not only provides structural strength but also allows the duct to be dragged on rough surfaces without abrasion or damage.
Whether you need to supply hot air for temporary construction heating, extract aggressive fumes in chemical plants, or handle abrasive dust in workshops, this duct delivers unmatched performance. It is flame retardant, waterproof, and resistant to alkalis, acids, and most industrial chemicals. Choose from standard colors (grey, yellow, black, blue) or request custom colors for large orders. Insulation levels can be tailored to your specific temperature requirements, from basic heat resistance up to 1200°C.
The NUOENWEI Oxford cloth high temperature air duct is meticulously engineered for applications that demand both flexibility and extreme temperature tolerance. The duct consists of:
Inner Layer: High-temperature resistant fabric (fiberglass based) that withstands continuous exposure to hot air, steam, and mild chemicals.
Middle Insulation Layer: Thick thermal barrier that minimizes heat loss and protects the outer surface, available in various grades to match your temperature needs (–45°C up to 400°C, 600°C, or even 1200°C).
Outer Layer: Heavy-duty Oxford cloth coated for abrasion, water, and flame resistance, reinforced with an embedded spiral steel wire that also acts as a wear strip when dragging.
The steel helix is fully encapsulated to prevent corrosion and provides exceptional crush resistance and flexibility. The duct can be bent arbitrarily without kinking, making it easy to install in tight spaces. Its robust construction ensures a long service life even in continuous use.
