The damper actuators are devices powered by a motor that is used for operating a damper. It adjusts the flow of the smoke and air. There are 2 basic types of this kind of actuator, these are the following:
1.) Electric damper. This type of damper actuator differs in output and terms. The options include the following:
- 0 – 12 VDC
- 2 – 10 VDC
- 4-20 mA
So, the products with characteristics such as low power consumption, reverse action, thermal protection, and direct action are commonly available.
2.) Pneumatic damper. This type of damper actuator has a starting point of measured in PSI (pounds per square inch). The span will be a primary function of a spring. The spring is designed to produce an equal force on both the return strokes and the power.
General damper actuators are available now. It is specialized in smoker and fire damper actuator.
How to install
You can easily and quickly install a damper actuator. The entire set of a damper actuator includes the anti-rotation brackets and screws, self-centering shaft adapter, locking clip, position indicator, Hex key, and open-air GCA spring return electronic damper actuator, and the installation instructions. To complete the installation, you may need the following additional tools:
- Drill with soft tapping screws
- screw gun
- small screwdriver
- Tape measure
Determine the rotation direction of the damper is the first step to do. It can orient the actuator to move clockwise or counterclockwise operation. Damper actuator should shaft link. These are important things to check when installing the damper actuator.
When choosing a damper actuator, it needs an analysis of the products. The specifications of the device are very important. Why? You need to buy the right type of damper actuator intended for the work or project. It is something like you will not use a ruler to cut paper. The situation is the same as how you are going to buy a type of damper actuator. So, you need to make sure that you are specific on the type of damper actuator that you are buying. The parameters include the following:
- Operating. The operating temperature will be measured in degrees Celsius or degrees Fahrenheit. It can indicate the full required ranges of the ambient temperature for the damper actuator.
- Supply voltage. This requires a minimum voltage supply to operate the damper actuator.
- Torque. This requires a range of the output which is often measured in in-lbs.
The damper actuator carries specifications for position feedback and shaft diameter.
