General Information

Application

  • Circular VAV terminal units for use in ventilation and air conditioning systems
  • For virtually all control, inductor and shut-off tasks in the supply air or extract air area
  • Also for unfavourable upstream conditions at low airflow velocities
  • Closed-loop volume flow control using an external power supply
  • For variable or constant volume flow systems
  • Shut-off via override control by others

Special features

  • High effective pressure signal at a small angle of attack
  • Factory set-up or programming and aerodynamic function testing
  • Volume flow rate can be measured and subsequently adjusted on site; additional adjustment tool may be necessary (depending on the variant of the control component)
  • Effective pressure monitoring tubeless via damper blade
  • Effective pressure transmission through effective pressure channel in shaft
  • Any direction of flow with dynamic transducer
  • Any installation orientation, even with static transducers
  • Suitable for airflow velocity of 0.5 - 13 m/s
  • Compact dimensions for use in confined ceiling areas
