  • Eight precautions for debugging axial flow fans

    Eight precautions for debugging axial flow fans

    The axial fan allows full-voltage starting or step-down starting, but it should be noted that the current at full-voltage starting is about 5-7 times the rated current. The axial-flow fan's step-down starting torque is proportional to the square of the voltage, when the grid capacity is insufficient... read more
