Double Layer Aluminum Flexible Duct is a high-performance flexible air duct manufactured with 2 layers of aluminum foil laminated with PET film and reinforced by a steel wire helix. This multi-layer construction enhances mechanical strength, air tightness, and durability compared to single-layer flexible ducts.Designed for HVAC ventilation and air distribution systems, this aluminum flex duct offers excellent flexibility for installation in confined or complex spaces. It can be fully compressed for storage and transportation, helping reduce logistics costs while maintaining consistent airflow performance during operation.With strong resistance to heat, moisture, and corrosion, double layer aluminum flexible duct is widely used for return air systems, exhaust ventilation, and general-purpose HVAC duct connections in both residential and commercial projects.
