HVAC Duct
The Lambro 4-inch x 8-foot flexible aluminum duct (semi-rigid) with quick connecting collars is ideal for general HVAC venting applications that require air expulsion from the home. Suitable for HVAC systems, our semi-rigid ducts ensure minimal air leakage and optimal performance, resulting in significant energy savings and improved indoor air quality.
The duct is ideal for new and replacement installations. The semi-rigid duct is flexible; the corrugations throughout prevent collapsing and allow for easy duct bending when needed. Class 0 aluminum is corrosion-resistant, non-combustible, and flame-resistant, with a maximum operating temperature of 430°F. When installing the duct, you can cut it to length to allow for stretching for maximum airflow.
A semi-rigid and lightweight non-insulated flexible duct, the triple lock manufacturing process uses a dead soft aluminum strip, spirally wound and mechanically joined together, forming an airtight and leakproof triple lock seam. This self-supporting and corrosive-resistant product provides excellent strength and flexibility and is adaptable to any low—to high-pressure heating, ventilation, and air conditioning system.
Please be sure to check local building codes before installation.
