DC fan and fan motor
DC inverter fan motor more higher efciency in part load running
■ 16-stage speed control; high efciency running especially in low speed
■ Efciency increase 45% comparing with AC motor and power input largely decrease big diameter fan
■ 570mm big diameter fan, more big air ow and more higher efciency
