　　（1） Overview of Negative Pressure Fan

　　Negative pressure fan is a type of ventilation fan, belonging to axial flow fan, which is mainly used in negative pressure ventilation and cooling projects and is called negative pressure fan. The negative pressure ventilation cooling project includes both ventilation and cooling aspects, and solves both ventilation and cooling problems simultaneously. Negative pressure fans are also used in positive pressure water curtain environmental air conditioning, positive pressure air supply, positive pressure blowing and other fields. Negative pressure fans have the characteristics of large volume, ultra large air duct, ultra large blade diameter, ultra large exhaust volume, ultra-low energy consumption, low speed, and low noise.

　　（2） The principle of negative pressure fan

　　By utilizing the cooling principle of air convection and negative pressure ventilation, fresh air is naturally drawn in from the opposite side of the installation location - the door or window, and the hot and humid indoor gases are quickly forced out of the room. Any ventilation problems can be improved, and the cooling and ventilation effect can reach 90% -97%.
