NUOENWEI Clamped High Temperature Duct | Single-Layer Iron Clamp Fabric Duct -15°C to 300°C
NUOENWEI's Single-Layer Clamped High Temperature Duct is a heavy-duty flexible ventilation solution engineered for efficient warm air conveyance in demanding thermal environments. Built with a single layer of high-temperature-resistant fabric and reinforced by a sturdy iron clamp structure, this duct operates reliably across a temperature range of -15°C to 300°C. Available in inner diameters from 200mm to 800mm with fully customizable lengths, it is purpose-built for industrial heating systems, construction site warming, and high-temperature exhaust applications where standard ducting would fail.
Unlike commodity ducts that rely on thin aluminum or PVC walls, the NUOENWEI clamped high temperature duct uses a robust fabric construction secured by an iron clamp mechanism. This design provides superior structural stability, tight sealing at connection points, and excellent resistance to thermal degradation. The iron clamp reinforcement prevents duct collapse under negative pressure and ensures a secure, leak-free connection between duct sections and equipment outlets.
Engineered for Extreme Heat. Built to Last.
When your operation runs hot, you need a duct that won't buckle, tear, or degrade. The NUOENWEI Single-Layer Clamped High Temperature Duct is designed from the ground up to handle continuous exposure to heated air streams reaching 300°C — far beyond the limits of conventional flexible ducting.
The core construction features a single layer of specially treated high-temperature fabric, selected for its thermal stability, tensile strength, and resistance to abrasion. This fabric is reinforced with an iron clamp structure that serves two critical functions: it maintains the duct's circular cross-section under pressure and provides a rigid, reliable connection interface at each end. The result is a duct that stays open, stays sealed, and stays on the job.
Whether you're routing hot air from an indirect-fired heater, venting exhaust from an industrial oven, or supplying warm air through a temporary heating network, this duct delivers consistent airflow with minimal heat loss. Its lightweight, flexible body allows for quick installation around obstacles, while the iron clamp ends ensure a secure fit that won't slip or leak.
Available in diameters from 200mm to 800mm and in any custom length you require, the NUOENWEI clamped high temperature duct adapts to your system — not the other way around.

Product Advantages
Exceptional Thermal Endurance (Up to 300°C)
The NUOENWEI clamped high temperature duct is rated for continuous operation from -15°C to 300°C. This wide thermal window means one duct can handle everything from cold-weather construction heating to hot exhaust extraction — no need to swap equipment as conditions change. Standard flexible ducts typically max out well below 150°C, making this duct a clear upgrade for any high-heat application.
Iron Clamp Reinforcement for Structural Integrity
The integrated iron clamp isn't just an accessory — it's a structural component. It maintains the duct's circular profile under airflow pressure, prevents collapse during negative-pressure exhaust, and creates a rigid, mechanically secure connection point. This translates to fewer leaks, less energy waste, and a safer working environment.
Efficient Warm Air Transfer with Minimal Heat Loss
The single-layer fabric construction is optimized for heat retention. When conveying warm air over distances, the duct's thermal properties help maintain temperature at the delivery point, improving the efficiency of your heating system and reducing fuel consumption.
Fully Customizable Diameter and Length
With inner diameters from 200mm to 800mm and lengths cut to your exact specification, this duct integrates seamlessly into existing systems. Whether you need a short run from a portable heater or a long distribution line across a large facility, NUOENWEI builds to your dimensions.
Lightweight and Flexible for Fast Installation
Despite its heat resistance and iron reinforcement, the duct remains lightweight and highly flexible. It bends around corners, threads through tight spaces, and can be installed by a single technician without special tools. When not in use, it collapses for compact storage.
Durable Fabric Resists Abrasion and Tearing
The outer fabric layer is treated to withstand contact with rough surfaces, making the duct suitable for job sites where dragging across concrete or gravel is unavoidable. This durability reduces replacement frequency and lowers total cost of ownership.
Application Scenario
Portable Heater Ducting on Construction Sites
Indirect-fired diesel and gas heaters are the backbone of winter construction. The NUOENWEI clamped high temperature duct is the ideal companion — routing hot air from the heater unit into enclosed work areas, curing tents, or ground-thawing zones. The 300°C rating comfortably handles the output temperatures of most portable indirect heaters, while the iron clamp ensures a secure connection that won't pop off under vibration.
Industrial Oven and Furnace Exhaust
Manufacturing processes involving industrial ovens, kilns, and furnaces generate exhaust streams that rapidly destroy ordinary ducting. This duct is engineered to capture and route those high-temperature fumes safely. Its single-layer fabric construction provides a balance of thermal resistance and flexibility, making it suitable for exhaust runs that require bends and offsets.
Temporary Building Heating and Event Climate Control
When temporary structures — warehouses, exhibition halls, event tents — need rapid heating, flexible ducting is the fastest way to distribute warm air. The NUOENWEI clamped high temperature duct delivers heated air efficiently and can be quickly deployed, repositioned, or removed as the space's requirements change.
HVAC High-Temperature Supply Lines
In commercial and industrial HVAC systems that handle process heat or high-temperature supply air, standard flex duct is not an option. This duct bridges the gap between rigid metal ductwork and the need for flexibility, allowing designers to route hot air around obstacles without custom sheet-metal fabrication.
Chemical and Plastics Processing Ventilation
Many chemical and plastics processes release heated fumes and vapors that require extraction. The fabric construction of this duct offers resistance to a range of industrial chemicals, while the high-temperature rating handles the thermal load of the exhaust stream.
Ground Thawing and Frost Protection
In cold-climate construction, ground thawing is essential before excavation or concrete pouring. Portable heaters connected to NUOENWEI high temperature ducts distribute heat evenly across frozen ground, accelerating the thawing process without the risk of duct failure.
