Release time:

2019-03-26

1. Current: The current is measured after continuous rotation for 3 minutes 2. Speed: the rate is measured after 3 minutes of continuous rotation 3. Starting voltage: the voltage that can start the fan operation after turning on the switch "ON" 4. Input power: The input power is measured after 3 minutes of continuous rotation 5. Lock current: can lock the fan of the machine, lock the current in the fresh air lock machine 3 minutes 6. Air flow data and pressure data are measured according to "AMCA standard" or DIN24163 rules. The data are measured in double pressure chambers, and the pressure data on each side of the pressure chamber need to be measured. 7. Noise standard: The noise standard test refers to the DIN45635 standard, and the measurement is carried out in the soundproof room. The microphone is placed at one meter of the fan.
