This 12-inch round adjustable butterfly damper provides an effective field solution for balancing air distribution systems. Positioned directly behind ceiling diffusers or duct takeoffs, it allows technicians and homeowners to control velocity and air volume effortlessly. The mechanical handle provides smooth adjustments to fine-tune comfort levels in specific rooms.
Constructed with a resilient finish, this brown butterfly damper is preferred by professional HVAC installers for its clean integration with matching brown registers. It acts as a reliable volume regulator, helping eliminate hot or cold spots by re-routing air delivery to undersized branches or high-demand residential zones.
Before purchasing, ensure your duct collar or diffuser inlet features a standard 12-inch round configuration. Proper installation involves attaching the damper securely to the rear of the grille assembly, allowing the operator to adjust airflow manually via the center screw or lever mechanism without dismantling the ceiling fixtures.
