三、Use  place

Compared with ordinary axial flow fan, exterior rotor axial flow fan is more efficient, low noise, small vibration, compact structure, appearance is more beautiful, the impeller directly fixed on the motor outside circle, makes the axial size is shorter, longer service life, widely used in ventilation, air conditioning and refrigeration technology, wind power and mechanical engineering, finish machining equipment industry, etc
