Multilayer air duct GeoFlex Exhaust HT-450

flexiblespiralround

Short description
The GeoFlex Exhaust HT-450 is a high-temperature exhaust/supply hose for hot air, fumes, exhaust gases and dust. Constructed from silicone-coated fibreglass with a stainless/galvanised steel spiral, it withstands continuous temperatures from -60°C to +450°C (short-term up to +500°C). The compressible design and outer wear strip make it suitable for mobile and fixed extraction in demanding industrial and vehicle exhaust applications.

What do you get?

• Temperature resistance up to +450°C (short-term +500°C).
• Designed for hot air, fumes, exhaust gases and dust extraction/supply.
• Silicone-coated fibreglass outer for thermal durability.
• Reinforcement by stainless/galvanised steel spiral for stability.
• Compressible construction for easy handling and storage.
• Flame-retardant materials and external wear strip for mechanical protection.
• Available in multiple diameters and standard lengths; custom sizes on request.

Product information
The hose features a multi-layer wall with a silicone-coated fibreglass outer and an internal stainless/galvanised steel spiral providing axial and radial stability. Temperature range is continuous -60°C to +450°C with short-term resistance up to +500°C. The compressible profile permits use in confined spaces and supports both fixed installation and mobile extraction systems such as vehicle exhaust extraction and industrial ovens. Standard lengths range from 1 m to 10 m; non-standard lengths and customised assemblies are available on request.
