FAQ

What are the types of electric fans?
According to the structure of the motor can be divided into: a single-phase capacitor type single-phase, three-phase, shaded pole induction, DC and AC / DC series excitation commutator type electric fan.
What's the effect of the air circulation fan?
In the case of air circulation fan, no need for air conditioning, nor the same as ordinary fans blowing uncomfortable, completely feel the wind blowing
Which items should we pay attention to selecting electric fans?
Select the fan film requires hard, smooth, no bubbles, no scratches, peeling paint, paint show, hanging or different color paint mixed phenomenon.
Why not head fan to blow?
The blower is suitable for choosing the head.

For the elderly with cardiovascular and cerebrovascular diseases, severe stroke can be induced
Why does the electric fan always rotate clockwise?
The fan blade of a conventional fan has a tilt angle (the steering is designed from the angle of the tilt angle). The motor causes the fan to rotate and the space-time is compressed, causing air flow (resulting in wind). The direction of flow is related to the direction of the fan's rotation and the inclination of the fan blade.
Where does the wind from the electric fan come from?
At the same time, the air velocity of the diagonal line must be faster than that of the straight line, causing the air pressure on both sides to vary. The air flowing along the straight line flows to the side of the air where the wind is formed
What is the difference between air conditioner speed regulation and electric fan speed regulation?
Variable frequency air conditioning is to change the frequency of motor power supply to achieve speed regulation, in fact, the frequency adjustment will also change the voltage.
How much electricity does the ordinary fan use in a day?
