Incremental HVAC Damper Actuators
When duct airflow varies from the setpoint, these actuators open and close until the system requirement is restored. Use to automatically adjust dampers to regulate airflow. Actuators attach to the damper shaft to rotate it open and closed when signaled by a controller (not included).
Actuator with spring return can be set to return the damper to an open or closed position if the power fails. Use the crank for precise adjustments.

Proportional HVAC Damper Actuators
This actuator provides better control than incremental actuators because it is constantly being positioned in response to duct airflow requirements. Use to automatically adjust dampers to regulate airflow. It attaches to the damper shaft to rotate it open and closed when signaled by a controller (not included). Actuator can be set to return the damper to an open or closed position if the power fails. Use the crank for precise adjustments.

Incremental and Proportional HVAC Damper Actuators
Actuators automatically switch between incremental and proportional control to adjust dampers to regulate airflow. Actuators attach to the damper shaft to rotate it open and closed when signaled by a controller (not included).
