This Atco 30 Series flexible duct is a UL 181, Class 1 Air Duct designed for reliable performance in HVAC systems. It features a strong, tri-directional fiberglass scrim reinforced, metallized polyester outer jacket for durability. The duct's air-tight inner core, made from a double lamination of polyester around a steel wire helix, is ideal for low-to-medium operating pressures.Wrapped in a thick blanket of R-8 fiberglass insulation, this duct offers superior thermal characteristics compared to standard models. This construction ensures energy efficiency and prevents fiberglass erosion into the airstream, making it suitable for both supply and return air applications in residential and commercial settings.
