Description

ATCO’s UPC #050 is a UL 181 Class 1 Air Connector which meets the requirements of NFPA (90A & 90B). UPC #050 is manufactured with a tough triple ply duct wall construction. 25’ lengths, which can be easily cut to desired length, are compressed and packed in small, easy to store cartons. The UPC #050 is air-tight and is designed for low to medium operating pressures in HVAC systems.

A triple lamination of tough metallized polyester, aluminum foil, and polyester encapsulates a steel wire helix and forms the air-tight uninsulated flexible duct of ATCO’s UPC #050.

UPC #050 is designed to be used as a supply, return, and exhaust duct in low to medium pressure heating, air conditioning, and exhaust systems. ATCO’s UPC #050 can be used in an air distribution system, connecting ducts, mixing boxes, diffusers, light troffers, room inlets, or other terminal devices where an uninsulated flexible air connector is required.
