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.

  • Air-tight Inner Core - Energy efficient / No fiberglass erosion into air stream.
  • Encapsulated Wire Helix - No unraveling when cut to length / Quick installation
  • Smooth Inner Core - Low friction loss / Low operating cost.
  • Thick Blanket of Fiberglass Insulation - Energy efficient / Excellent thermal characteristics
  • Durable Black Polyethylene Jacket - Tear and puncture resistant / Low maintenance.
  • Lightweight Compact Carton - Reduces warehouse and Jobsite handling cost.
