How do I choose an actuator for a damper?
To size an actuator, you need to find the damper size and the Rated Torque Loading. Once you have these values, you can calculate the required inch-pounds.
When choosing an actuator, it is important to consider the control signal, fail-safe function, mounting, and ambient conditions.
How long do damper actuators last?
It depends on the specific dampers you have and general usage conditions. However, the average butterfly damper should last about 20 years
as long as you remember to clean and maintain your system. Electric dampers may only last about 15 years before the motor starts to experience problems.
What causes a damper actuator to go bad?
During wear and tear, chattering and binding stack up in the damper and torque happens to be more than what is required will cause damage to the actuator.
Undersizing will potentially damage your actuator gearbox in the long run where the breakaway torque will cause the gearbox to be worn off or even crack.
