The HART COOLEY r22 10 brn is a round metal damper assembly designed for use with 10-inch duct systems. This component regulates airflow within HVAC ductwork by providing a manual or automated shutoff and balancing point inside a round duct run. Built from metal construction, it is suited for installation in residential and light commercial forced-air systems. HVAC technicians and sheet metal installers work with this assembly as part of a complete duct distribution layout. The 10-inch nominal size positions it for main trunk takeoffs and large branch runs where airflow volume control is required.
This damper assembly is intended for use with 10-inch round duct systems, specifically noted as compatible with the 1500 series round duct system. It is appropriate for residential and light commercial HVAC installations where round metal ductwork is used for supply or return air distribution. The assembly fits within standard 10-inch round duct runs and is installed during new construction or retrofit duct work by licensed HVAC technicians or sheet metal contractors.
Designed for use with 10-inch 1500 series round metal duct systems as noted in product data.
Installation should be performed by a licensed HVAC technician or qualified sheet metal contractor. Power down the air handling unit and confirm the system is de-energized before accessing ductwork. Secure the damper assembly within the duct run according to local mechanical codes and manufacturer guidelines. Do not modify the damper blade or frame to fit non-standard duct openings.
