On/Off floating action electric damper actuator

On/Off floating action electric damper actuator


This is a small electric damper actuator. Normally be used for variable air flow control device of cooling, heating, ventilation or the ventilation of an industrial process. It may also work with the other devices to control temperature, humidity or pressure.


The electric damper actuator NACA..-05 series combines a "gear box", "holder" and "electric control circuit" to be an actuator. It has the following features:

  • ON-OFF, 3 points floating control.
  • This series has 2~5Nm torque, adapts to small damper.
  • Lock to the rotate bar.
    Round: φ 6~16mm, Square: 5~12mm.
  • One SPDT contact, can set position switch.
  • CW or CCW motor directional control.
  • Save energy when stop. Runs at low-noise.
  • Manual operation and setting the rotate angle.
  • Shows damper position on its cover.
