Rotary

Explore our full range of damper rotary actuators for HVAC systems

Check out our set of damper rotary actuators in our IACS store manufactured by Belimo, Siemens, and Danfoss.

Damper Rotary Actuators, thanks to their spinning motion, control the airflow into the HVAC system. Our IACS support team can answer technical questions.

How a damper rotary actuator works

The actuator converts the energy into a physical rotation, which is known as Torque and generates the appropriate pressure to affect the fluid/path airflow. See our IACS blog article for further details.

Our Sales Team at IACS is available to answer questions about pricing and inventory levels.
