YWF4D series axial fans are external rotor fan motors. These motors have characteristics of compact structure,convenient installation, energy conservation and high efficiency.

YWF4D series axial fan motors have two types, single phase asynchronous capacitor run fan motor and three phases asynchronous fan motor, They are widely used in condenser, evaporator and other refrigeration equipment and ventilating cycle areas.

The insulation class of the YWF4D series axial fans is B or F.

Voltage: The voltage of the single phase motor is 220V/60Hz,and the voltage of the three phases motors is 440V/60Hz. We can also supply voltage of the three phases motors is 380V/50H We can alsos ply other fan motors with different voltages and frequencies according to clients' requirement.

The standard length of the electrical wire on the fan is 1.5m and we can also supply the fan motors with connection box for clients' choices.

The applicable ambient temperature of the fan motors used in condenser is from -30°C to 60°C.

The average service life of motors is over 30000 hours.

All motors in our factory got CE approval in Europe and CCC safety certificate in China.

Before operating the motor, make sure to put the earth wire of the motor connected with the external grounding device.
