Hart Cooley 155 10 Brn 10 Inch Ring Damper Assembly

Product Description

The HART COOLEY 155 10 brn is a 10-inch ring damper assembly designed for use with 10-inch round duct systems. Ring dampers are installed in-line within duct runs to regulate or shut off airflow to individual zones or registers. This assembly provides manual or system-controlled airflow adjustment at the point of distribution. Licensed HVAC technicians and sheet metal contractors install this type of damper during new construction, renovation, or service work on forced-air ventilation and comfort-cooling systems.

This ring damper assembly is suited for residential and light commercial forced-air HVAC applications where 10-inch round duct is used. It is typically installed at branch takeoffs, trunk-to-branch transitions, or directly behind register boots to balance airflow across multiple zones. The assembly is intended for use with the 150-series duct fittings in the HART COOLEY product line, as indicated by the supplier reference to the 10-inch 150-series compatibility.

Installation Notes

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 the duct run. Secure the damper assembly in accordance with applicable mechanical codes and ensure all duct connections are sealed to prevent air leakage. Do not restrict the damper blade travel during installation.
