Damper Actuator/Air Brake operates with minimal noise.
Press Release Summary:
Suited for HVAC market, ultra-quiet spring return damper actuator incorporates Whisper Motion(TM) air brake and Synchron® AC synchronous motor. Air brake adds virtually no resistance during power open cycle but adds drag as acceleration increases during spring return cycle. This drag reduces rotational kinetic energy, which helps prolong gearing life and minimizes operational noise.
Original Press Release:
Damper Actuator/Air Brake
Hansen Corporation is proud to announce the release of its ultra-quiet spring return damper actuator for the HVAC market. The Hansen actuator incorporates the patent pending Whisper Motion(TM) air brake and the always reliable Synchron® AC synchronous motor.
The air brake adds virtually no resistance during the power open cycle but adds drag as acceleration increases during the spring return cycle. This drag reduces rotational kinetic energy by 40% over a brakeless unit which is beneficial in 2 ways. The slower return speed means longer life for the gearing but the big advantage is much quieter operation. Sound energy is reduced 80% compared to a brakeless unit on an unattached actuator and that means the "wind-up" noise common to most actuators is a thing of the past. The name Whisper Motion(TM) was chosen to personify the consumer benefits for residential and office installations.
Hansen has manufactured motors for 100 years.
