Description
PRA Balancing Damper Adjustment And Measurement Unit
The PRA Balancing Damper airflow rate is adjusted by turning the adjustment knob in order to change the aperture size of the adjustment cone formed by iris blades. Once the opening area is reduced, the airflow rate decreases and the total pressure loss caused by the device increases. The PRA Balancing Damper airflow can be determined by measuring the differential pressure in the measurement taps.
