Description: Atco #080, 086, and 088 are UL 181, Class 1 Air Ducts and are manufactured with a durable black polyethylene jacket. The inner core of all three products is air-tight and designed for low-to-medium operating pressures in HVAC systems. Atco #086 and 088 have increased insulation for superior thermal performance.
Construction: A double lamination of tough polyester which encapsulates a steel wire helix forms the air-tight inner core of the Atco #080, 086,and 088. The double-layer core of each product is wrapped in multiple thicknesses of fiberglass insulation. All three products are sheathed in a durable polyethylene jacket.
