Hansen's 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. 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. The air brake add virtually no resistance during the power open cycle but adds drag during the spring return cycle that reduces kinetic energy by 40%. The slower speed results in longer motor life and quieter operation. The name Whisper Motion was chosen to emphasize the consumer benefits for residential and office installations.
