Q:What are the common faults of electric fans?
The fan device is composed of a motor, a circuit breaker motor overheating, if local coil winding short circuit occurs, will let the heat increase in a short time, this case motor will "strike" real.
Q:When did the electric fan start to appear?
25 years later, Ecclestone engine and electrical company in the United States, and developed the world's first electric fan gear driven around the head
Q:What is the problem of slow fan speed?
The capacitive value of the starting capacitor is caused by a decrease in the capacitance
Q:Which items should we pay attention to selecting electric fans?
Choose the electric fan to regard decoration has no damage; net cover before and after anastomosis closely, no deformation, mesh wire joints loose desoldering etc.. Flexible lifting fan.
Q:Does the fan blow the door open or closed?

A multi throw switch is cheaper than a rheostat
Q:What's the effect of the air circulation fan?
It's also the smallest wind. It's really smaller than the tower fan at the same price. The biggest sound is still big
Q:What's the difference between a cool fan and an electric fan?
