The Atco #031 Series is a UL 181, Class 1 insulated flexible air duct designed for low-to-medium pressure residential and commercial HVAC systems. It is suitable for use as a complete duct system or as a branch duct for supply and return air, connecting to mixing boxes, diffusers, or other terminal devices.This duct is constructed with an air-tight, double-ply polyester inner core that encapsulates a steel wire helix. The core is wrapped in a thick blanket of R-8 fiberglass insulation and sheathed in a rugged, metallized polyester jacket for lasting durability.
Durable Construction: Features a tough, tri-directionally reinforced metallized polyester jacket that is tear and puncture resistant.Air-Tight Core: A double lamination of polyester forms an air-tight inner core to improve energy efficiency and prevent fiberglass erosion into the air stream.Easy Installation: The encapsulated steel wire helix prevents unraveling when the duct is cut to length, simplifying installation.Efficient Airflow: A smooth inner core design results in low friction loss and helps reduce operating costs.Formaldehyde-Free: Insulated with Owens Corning EcoTouch fiberglass insulation, which is certified for low chemical emissions and is formaldehyde-free.
