Are you familiar with how to interpret this graph?

Air Flow (Q): This represents the volume of air moving through the fan’s outlet or intake over a specific period. It is typically measured in CFM (cubic feet per minute) or CMM (cubic meters per minute).

Air Pressure (P): This indicates the pressure difference created by the fan between the air outlet and intake. It is usually measured in millimeters of the water column (mmH₂O), similar to how a millimeter mercury column measures atmospheric pressure. However, the difference is minimal, so mmH₂O is the standard unit.

The airflow volume and pressure can be regulated by adjusting the fan speed or using the gate, ensuring the maximum speed does not surpass the specified limit.

气流量 (Q)：这代表风扇出口或进气口在特定时间内通过的空气体积。通常以CFM（每分钟立方英尺）或CMM（每分钟立方米）为单位进行测量。

气压 (P)：这表示风扇在空气出口和进气口之间产生的压力差。通常以水柱毫米（mmH₂O）为单位进行测量，类似于使用水银柱测量大气压力。然而，二者的差异很小，因此mmH₂O是标准单位。

通过调整风扇转速或使用调节阀门，可以控制气流量和气压，确保最大转速不会超过规定的限制。
