Dampers for Drop-Ceiling Diffusers


For use with drop-ceiling diffusers and ready-to-connect drop-ceiling diffusers, these dampers regulate airflow. Dampers mount to a collar.
Dampers with a butterfly opening/closing style open on a middle hinge. The removable handle adjusts the damper to control airflow and is easier to adjust than dampers with a radial opening/closing style.
Dampers with a radial opening/closing style open in a circle for more precise airflow than dampers with a butterfly opening/closing style.
