Rotary actuators are used in ventilation and air conditioning plants to regulate and shut off air dampers:

  • For damper areas up to approximately 0.8 m2 (Reference value: Always comply with the damper manufacturer's specifications).
  • Suitable for use with 2-position and 3-position controllers as well as modulating controllers (DC 0/2...10 V) to control air dampers.
  • We recommend a minimum pulse length of 500 ms on rotary actuators operated with 3-point control to ensure continuous and accurate operation.
