Description:

ATCO's UPC #030 is a UL 181 Class 1 Air Duct and is manufactured with a reinforced metallized polyester jacket. The UPC #030 inner core is air-tight and is designed for low-to-medium operating pressures in HVAC systems.

Construction:

A double lamination of tough polyester which encapsulates a steel wire helix forms the air-tight inner core to ATCO's UPC #030. The double layer core is wrapped in a thick blanket of fiberglass insulation and sheathed in a rugged and durable reinforced metallized polyester jacket.

Applications:

UPC #030 is designed for indoor use as a supply and return air duct in residential and commercial low-to-medium pressure heating and air conditioning systems. ATCO's UPC #030 can be used as a complete air duct system and/or a branch duct connecting to mixing boxes, diffusers, light troffers, room inlets or other terminal devices.

Air Friction Chart

Air Flow 'SCFM':

STRAIGHT RUN.

FD 72-R1 Test Code of the Air Diffusion Council. Friction loss is computed in inches of water gauge per 100 ft. of straight duct. By using CFM or FPM values for a given duct dimension, the friction loss can be determined. Conversion of CFM to FPM also can be made.
