Hart Cooley 155 06 Brn 6 in Ring Damper Assembly

Product Description

The HART COOLEY 155 06 brn is a 6-inch ring damper assembly designed for use with 6-inch 150-series round duct systems. Ring dampers provide manual airflow control at individual supply or return openings, allowing technicians to balance airflow across zones without additional components. This assembly includes the damper ring and actuating hardware needed for a complete installation. HVAC technicians and sheet metal contractors install this type of fitting during new construction rough-in or when rebalancing existing residential or light commercial duct systems.

This ring damper assembly is sized for 6-inch round duct and is intended for use with the HART COOLEY 150-series duct fittings. It is a common component in forced-air residential systems where zone-level airflow adjustment is required. The brown finish indicates a specific color designation within the 155-series product line, which may correspond to a coded identification or finish standard for the application.

Key Features

• 6-inch nominal size matches standard 6-inch round duct openings
• Ring damper design allows manual airflow restriction at the fitting level
• Compatible with 150-series round duct system components
• Color-coded brown finish for product identification within the 155 series

Compatibility

Designed for use with 6-inch 150-series round duct fittings in forced-air HVAC systems. Confirm fitting series and nominal duct diameter before installation.

Installation Notes

Installation should be performed by a qualified HVAC technician or licensed sheet metal contractor. Shut down the air handling unit and de-energize the system before working in the duct system. Secure the damper assembly per manufacturer instructions and verify the damper blade moves freely through its full range before sealing the fitting. Local mechanical codes and SMACNA standards may apply to duct installation and balancing procedures.
