How to reduce the noise when the electric fan is too noisy?

The electric fan is too noisy. Ways to reduce noise:

1. If the accessories are loose, you can check all parts of the fan to see which parts of the fan are loose, and then tighten them before installing.

2. If the bearing is caused by lack of lubricating oil, a few drops of lubricating oil can solve the noise problem.

3. If it is not cleaned for a long time and there is too much dust inside, you can use tools to disassemble it, then clean it as a whole and install it again.

4. If it is caused by internal motherboard damage, it needs professional maintenance.

The function of electric fan is:

Fan refers to an electrical fan that uses primitive wind to cool down in hot weather. It is a device that is driven by electricity and generates airflow. By making the current flow through the internal fan to make it rotate, it is natural and has the effect of cooling down.

Household electric fan: After the household electric fan is electrified, the internal fan will rotate and become natural wind, so as to achieve a cool effect.

Industrial exhaust fan: mainly used for forced air convection. If you use an electric fan for a long time, it is easy to accumulate dust under its blades. This is because when the electric fan works, the blades rub against the air and the blades will be charged. Charged objects have the characteristics of attracting light objects and can absorb fine dust floating indoors.
