Damper Actuators

Hansen’s ultra-quiet spring return damper actuator is ideal for the HVAC market. Featuring the patent-pending Whisper Motion™ air brake and the always reliable Synchron® AC synchronous motor, our actuator design eliminates the wind-up noise that often occurs when the motor and geartrain start spinning at more than ten times their normal operating speed.

In fact, compared to Hansen, the other actuators on the market today generate five times the sound energy during the spring return cycle, resulting in the unwanted wind-up noise. Wind up noise is reduced to whisper quiet levels due to our patent pending air brake technology.
