3. The air -changing fan is a type of axial flow fan.It is mainly used for negative pressure ventilation cooling projects, called exhaust fans.The exhaust device has the characteristics of a large air duct, the large wind diameter, the large discharge volume, ultra -low energy consumption, low speed, low noise and other characteristics.The use of air -changing fans and cooling water curtains can solve the problem of ventilation and cooling.
Choose the point of the air fan:
