Axial fan installed directly on the wall exhaust, how to determine its wind pressure?
At present, for the exhaust ventilation and the like, as long as the appearance of feeling to achieve ventilation effect can be, if it is a high standard of acceptance, it needs to be measured, on the measurement method, you can ask manufacturers to provide.
If you just want to know about the wind pressure, the current time can be measured.
If accurate measurements are required, it is necessary to connect a duct and then use a special calibration instrument to measure it.
The pressure on the nameplate is the wind pressure at the rated current. Directly determine the current, if the rated current, that is
