The fan is composed of external rotor asynchronous motor, plastic/aluminum impeller, etc. The motor has low temperature rise and has special advantages of ventilation, heat dissipation, self-cooling, etc. Thus, the reliability of fan service life is extended. The fan is a backward curved impeller, which has the characteristics of compact structure, large air volume, high static pressure, small vib
