The ProSelect PSRADU 6-inch radial damper is an essential component designed to control air volume within round sheet metal duct networks. This duct fitting allows installers to balance airflow delivery across different branches of a residential heating, ventilation, or air conditioning system. By carefully adjusting the internal damper position, technicians can ensure that individual living spaces receive the correct amount of conditioned air for consistent comfort.
Featuring a robust radial configuration, this 6-inch damper adjusts smoothly to restrict or open the air pathway inside the pipe without creating excessive turbulence or whistling noises. The direct mechanism provides reliable resistance against high velocity air streams, ensuring the damper blades remain in their set position after balancing is completed. This manual airflow regulation helps optimize system static pressure and overall energy efficiency throughout the property.
HVAC installers and sheet metal mechanics can integrate this 6-inch radial damper into standard rigid or flexible round duct segments. It installs directly inside the duct run, making it ideal for inline air balancing applications during new construction or system renovations. Technicians should verify nominal duct sizing, branch airflows, and structural accessibility requirements prior to completing the installation to facilitate convenient future air balancing adjustments.
