Caigang Phenolic Composite Duct is a lightweight, fire-resistant air distribution solution designed for HVAC systems in commercial and industrial settings. The product features a smooth inner surface to minimize friction loss, reducing energy consumption while maintaining efficient airflow. Its thermal performance is optimized with low thermal conductivity, ensuring minimal heat transfer and improved energy efficiency in climate control applications.
The duct is constructed from phenolic resin reinforced with aluminum foil, providing a robust yet lightweight structure that resists moisture, mold, and corrosion. Standard industry grades for phenolic composite ducts include Class 1 fire resistance and typical thermal conductivity values of 0.03 W/m·K. The material’s inherent stability allows for consistent performance across diverse environments, from dry industrial facilities to humid commercial spaces.
These ducts are widely used in ventilation, air conditioning, and industrial exhaust systems, particularly in sectors such as construction, manufacturing, and large-scale commercial buildings. Buyers typically source them in bulk for new installations or retrofits, with packaging designed to prevent damage during transit. The product’s durability and ease of installation make it a preferred choice for projects requiring long-term reliability and energy savings.
