Exhaust fan wind pressure and pressure correlation

1. If it is the same type of wind zhidao machine, then this statement is reasonable, the greater the wind, the greater the negative pressure.
2. But if it is not the same type of fan, this kind of speech is unreasonable,
Because: like this Jiafeng special negative pressure fan, even if it is 370W, the wind force will be greater than the 550W axial fan, and the negative pressure formed indoors will be stronger.China Industrial Exhaust Fans Suppliers

Also, the focus of different wind turbines is different. Some focus on wind power, and some focus on pressure. Low wind pressure is not necessarily low pressure.
