Square axial flow fan

        axial flow fan is also called the local ventilator, which is the same direction of the wind turbine with the direction of the air flow (i.e., the wind direction and Zhou Pinghang), such as electric fans, air conditioning fan is a fan of the axial flow, is a common used by industrial and mining enterprises.         the biggest difference is that the axial flow fan, and the conventional axial flow fan is the biggest difference is that the motor and the wind turbine blades are in a cylinder, the shape is square, more than the cylinder type fan.  ,  ,  ,  ,  , square axial flow fan with low investment cost, large air quantity, low noise, low energy consumption, stable operation, long service life, high efficiency, is the best choice for cooling ventilation in modern buildings;
