Application

Circular VARYCONTROL VAV terminal unit for use in room air conditioning systems (HVAC systems)
Also for unfavourable upstream conditions at low airflow velocities for supply air or exhaust air flow control in variable air volume systems
Closed-loop volume flow control using an external power supply
For controlling, restricting, or shutting off the airflow in air conditioning systems
Shut-off by means of switching (equipment supplied by others)

Special characteristics

Highly 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 tubeless pressure monitoring via damper blade
Effective pressure transmission through pressure channel in shaft
Suitable for any flow direction due to dynamic transducer
Any installation orientation even with static transducers
Suitable for airflow velocity of 0.5-13m/s
Compact dimensions for use in confined ceiling areas
