DUCT FLEXIBLE UNINSULATED 12inx25ft ATCO

ATCO's 500 Series is a UL 181 Class 1 Air Connector which meets the requirements of NFPA (90A & 90B). 500 Series is manufactured with a tough double ply duct wall construction. 25' lengths, which can easily be cut to desired length, are compressed and packed in small, easy to store cartons. The 500 series is air-tight and is designed for low to medium operating pressures in HVAC systems.

Series 500 is used as a supply, return and exhaust duct in low-to-medium pressure heating, air conditioning and exhaust systems. ATCO's series 500 can be used in an air distribution system, connection ducts, mixing boxes, diffusers, light troffers, room inlets or other terminal devices where an uninsulated flexible air connector is required.
