Introduction and Technical Structure

In the building industry and HVAC systems, there is always a need for pipes that are both lightweight and have suitable thermal performance. Kian Fan Industrial Production Group has provided an efficient and modern response to this need by producing aluminum flexible ducts. The structure of this product consists of several layers: two layers of high-quality aluminum foil placed on the outside and inside of the tube, and a layer of polyester in between which acts as insulation and reinforcement. Inside this multi-layer structure, a sturdy steel spring is embedded that maintains the cylindrical shape of the duct and allows for flexibility.
This product is manufactured in a diameter range of 10 to 45 centimeters and in 10-meter branches, creating suitable coverage for air transfer paths. One of the prominent technical features of Kian Fan's aluminum flexible duct is its operating temperature range, which includes -20 to +110 degrees Celsius; this makes its use possible in heating, cooling, and hot kitchen hood exhaust systems.

Key Features and Advantages

Kian Fan's aluminum flexible ducts offer numerous advantages that distinguish them from other products. The high flexibility of this product allows it to be easily routed around obstacles and in confined spaces such as suspended ceilings without the need for complex angular fittings. The very lightweight of these ducts reduces the dead load on the structure and makes transportation at the project site very easy.
Resistance to moisture and corrosion results from the aluminum layer, which prevents rusting and product degradation in humid environments. Additionally, this product has flame spread resistance properties, which is of high safety importance in building ventilation systems. High compressibility is another attractive feature of this product; meaning a 10-meter branch can be compressed to a very small volume, which results in significant savings in packaging, transportation, and storage. Easy installation and low cost also make it very cost-effective for use in concealed (Non-Exposed) environments.

Specialized Applications

The primary application of aluminum flexible ducts is in residential and commercial ventilation systems. This product is often used to connect main spiral or rectangular ducts to ceiling or wall diffusers. In central HVAC systems, the aluminum flexible duct acts as final branches (Take-offs), delivering conditioned air from the main duct to the room environment.
Also, in household and restaurant kitchen hoods for exhausting vapors and smoke out of the building, it is a suitable option due to its high temperature tolerance and resistance to grease and moisture. In heating systems such as stoves and heaters that require the transfer of hot air, this duct performs safely due to its tolerance of 110 degrees. Furthermore, it is widely used in bathroom and sanitary ventilation systems to exhaust moisture and stale air.

Conclusion

The aluminum flexible duct of Kian Fan Industrial Production Group, combining safety, efficiency, and economic features, has established a new standard in sub-ventilation systems. Using this product guarantees speed in project execution, cost reduction, and comfort in residential and commercial environments.
