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.

Construction

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.

Applications

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.
NOTE: Should not be used to vent appliances for cooking, or heating and clothes drying unless approved and recommended by appliance manufacturer.
