The DUC-PAC DP1001912.20.36 is a prefabricated sheet metal plenum designed for forced air HVAC systems. Built from 26 gauge steel, this plenum measures 19.5 inches by 20 inches by 36 inches and is sold in a case of 100 units. Plenums connect the air handler or furnace to the supply duct network, directing conditioned air from the unit into the distribution system. This part is installed by licensed HVAC technicians and sheet metal contractors working on residential and light commercial forced air installations.
This plenum is suited for new construction and replacement applications in forced air heating and cooling systems. The 26 gauge construction provides the rigidity needed for trunk line and equipment connections in standard residential installations. The 19.5 inch by 20 inch by 36 inch form factor accommodates common air handler and furnace cabinet configurations. Supplied in a quantity of 100, this case format supports contractors and distributors stocking for volume work.
Designed as an OEM-style prefabricated replacement and new-installation plenum for residential and light commercial forced air heating and cooling systems with matching cabinet or duct opening dimensions.
Installation should be performed by a licensed HVAC technician or sheet metal contractor in accordance with local mechanical codes and SMACNA duct construction standards. Power down and lock out the air handler or furnace before connecting or sealing the plenum. Secure all joints with appropriate sheet metal screws and seal with listed duct sealant or mastic per applicable code requirements.
