Where does the fan drip the oil?
To cheer for as long as the front axle and add a few points on the line, but to the correct way, the vertical axis, the oil in the bearings, give it a free fall, can get into the bearing, with hand up and down, make the oil more fast forward to the inside, repeated several times, will be able to solve the problem
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
What is the function of the fan blade?
The number of blades of a fan is often odd number, because it is easy to make the system resonance if the fan with even shape is used and the balance is not adjusted
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?

What is the problem of slow fan speed?
