Hart Cooley R22 08 Brn Round Damper Assembly 8 in

Product Description

The HART COOLEY r22 08 brn is a round metal damper assembly designed for use in ducted HVAC air distribution systems. Built for 8-inch round duct applications, this damper provides manual airflow regulation within a trunk-and-branch or radial duct layout. The all-metal construction supports durability in both supply and return air configurations. HVAC technicians and sheet metal installers working on residential and light commercial forced-air systems will find this assembly compatible with standard 8-inch round duct fittings, including the 1500-series collar.

This damper assembly is intended for installation in 8-inch round ductwork, specifically noted for use with the 8-inch 1500-series metal duct system. It is suited for residential forced-air heating and cooling applications where zone control or balancing is required at individual branch runs. The round profile integrates with standard snap-lock and slip-fit round duct connections common in residential new construction and retrofit HVAC work.

Key Features

• 8-inch round duct damper assembly for airflow balancing and zone control
• All-metal construction for durability in forced-air duct systems
• Designed for compatibility with 8-inch 1500-series round metal duct collars
• Manual damper operation for straightforward airflow adjustment

Compatibility

Designed for use with 8-inch 1500-series round metal duct systems. Verify duct collar diameter and series before installation.

Installation Notes

Installation is typically performed by licensed HVAC technicians or qualified sheet metal workers. Shut down the air handling unit and confirm the system is de-energized before cutting into or modifying ductwork. Secure all connections with sheet metal screws and approved duct sealant per local mechanical code requirements. Do not restrict damper blade travel during installation, as partial obstruction can cause airflow noise and pressure imbalance.
