Function
The air flow rate is adjusted by turning the adjustment knob in order to change the aperture size of the adjustment cone formed by SPIN blades. Once the opening area is reduced, the air flow rate decreases and the total pressure loss caused by the device increases. The airflow can be determined by measuring the differential pressure in the measurement taps.
