Hart Cooley R22 12 Brn Round Damper Assembly 12 in

Product Description

The HART COOLEY r22 12 brn is a round metal damper assembly designed for use with 12-inch round ductwork. This damper controls airflow within forced-air HVAC distribution systems by allowing a technician to regulate or shut off air to a branch or zone. Built from sheet metal construction, it is sized to fit directly into standard 12-inch round duct runs. HVAC installers and sheet metal contractors are the primary tradespeople who specify and install this component during new construction and retrofit projects.

This damper assembly is intended for use with 12-inch round duct systems, including applications that pair with the 1500-series AM Metal duct fittings. It is suited for residential and light commercial forced-air systems where manual or automated zone damping is required. The assembly is installed in-line within a supply or return air branch to provide airflow control at the duct level.

Key Features

• Designed for 12-inch round duct systems
• Metal construction for durability in forced-air duct applications
• Compatible with 1500-series AM Metal round duct fittings per input data
• Round damper assembly format for straightforward in-line duct installation

Compatibility

Specified for use with 12-inch 1500-series AM Metal round duct systems. Designed as an OEM-style replacement or new-installation damper assembly for 12-inch round ductwork applications.

Installation Notes

Installation is performed by licensed HVAC technicians or sheet metal contractors. Power to the air handling unit should be shut off at the disconnect before working inside duct systems. Ensure the damper blade seats fully and the assembly is secured to the duct without air leaks at the joint. All duct installations should comply with local mechanical codes and SMACNA standards.
