Damper Actuator | 140 in-lb | Non-Spg Rtn | 24V | On/Off



For On/Off control of dampers in HVAC systems. Actuator sizing should be done in accordance with the damper manufacturer’s specifications.

The actuator is mounted directly to a damper shaft up to 1.05” in diameter by means of its universal clamp, self-centered default. A crank arm and several mounting brackets are available for applications where the actuator cannot be direct coupled to the damper shaft.


The actuator is not provided with and does not require any limit switches, but is electronically protected against overload. The anti-rotation strap supplied with the actuator will prevent lateral movement.

The AMQB(X) series provides 95° of rotation and a visual indicator indicates position of the actuator. When reaching the damper or actuator end position, the actuator automatically stops. The gears can be manually disengaged with a button on the actuator cover.

The AMQB(X)24-1 actuators use a sensorless brushless DC motor, which is controlled by an Application Specific Integrated Circuit (ASIC). The ASIC monitors and controls the actuator’s rotation and provides a digital rotation sensing (DRS) function to prevent damage to the actuator in a stall condition. Power consumption is reduced in holding mode.

Add-on auxiliary switches or feedback potentiometers are easily fastened directly onto the actuator body for signaling and switching functions.

No issues with this device

The Belimo Damper Actuator has been proposed to me for my water heating system. After the initial months of use I have to say that it is economic consuming less power than its counterparts. Being really lightweight (less than 3.75lbs) gives you the chance to place it anywhere. The noise levels are limited, and it is maintenance-free as long as you reserve the requirements of the network. It also has an overload protection that is in direct relation to the on/off function to make you shut the hot water supply when you feel like it. This device has resolved all our previous issues and created economies of scale for us.

Reliable pressure controller

We have always been facing issues of pressure control to our air conditioning system. The fan coil needed a reliable pressure controller that we finally found when we mounted on the Belimo Damper Actuator. It has a low profile so that it can be placed virtually anywhere in your pipeline network. You get a high electronic protection against overload and the system has the ability to rotate 95 degrees showing you the exact position of the actuator. The on/off control is easy to achieve through the parameters you are giving to the actuator. A great device that saves you time and money and prevents possible accidents.
