Control units – extraction arms

Control units for improved working environments and lower energy consumption

Control units comprise specially adapted and tested components. A well designed system provides important benefits for the user:

  • Automatic systems provide energy savings
  • Lowest possible noise level
  • The control voltage is 24V

To help find the right system, a number of ready solutions are available, including:

  • Fan start and stop, with/without speed control
  • Fan start and stop, with switch
  • Individual damper control, plus fan start and stop via switch
  • Individual damper control, plus demand-based fan control via a pressure sensor and frequency converter

Control can be manual or automatic, with or without time delay.
