Typical Applications

Circular and Rectangular 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
