Damper Actuators

Introduction to Damper Actuators

What is it?

Damper actuators are devices that control the movement and position of dampers in heating, ventilation, and air conditioning (HVAC) systems. They can be used to regulate airflow and temperature in different zones or areas of a building.

Why we use it?

We use damper actuators to improve occupant comfort, optimize energy usage, and ensure system performance by regulating the flow of air in HVAC systems.

How it works?

The actuator typically contains an electric or pneumatic motor, which rotates a shaft to move the damper blade or vane into a desired position based on signals received from the building automation system or controller.

Major brands that manufacture it

Some of the major brands that manufacture damper actuators include Belimo, Honeywell, Johnson Controls, and Siemens.


There are different types of damper actuators, including electric and pneumatic models, with various torque ratings and travel angles to fit different applications. Some models may also feature additional functions, such as feedback sensors or communication protocols.

How do we select it?

When selecting a damper actuator, consider factors such as torque rating, travel angle, power supply requirements, compatibility with the damper assembly, and communication protocols. Also, make sure the actuator is compatible with your existing control and automation systems.

How to install it?

Damper actuators should be installed on the damper assembly according to the manufacturer's recommendations. They should be securely mounted using appropriate fittings or adapters, and any necessary wiring connections should be made to the building automation system or controller.

Wire connections required to receive the signals

The wire connections required to receive the signals from a damper actuator may vary depending on the specific device and building automation system. Typically, they will require a power supply connection and a communication signal wire that connects to the building automation system or controller. It's important to refer to the manufacturer's installation instructions for proper wiring connections.
