4.Air flow data and pressure data are determined according to " AMCA Standard" or DIN 24163 Rules.The data measurement is performed in a double pressure chamber and

It is necessary to measure the pressure data on each side of the pressure chamber.

5.Speed:The speed is measured after 3 minutes of continuous rotation
