Reliability of dust-proof cooling fan

The characteristic of the cooling fan is that it can actively mix air, speed up air mobility, and absorb dust. The dust will attach to the bearing, rotor and stator, which will affect the operation of the cooling fan to a certain extent. Therefore, it is necessary to select a dust-proof cooling fan when it is used in a dusty environment. The following are two key points for manufacturing a dust-proof cooling fan.

1. Double ball bearing shall be used, and the ball must be dust-proof and not easily disturbed.

2. During design, the outer frame is installed and raised together with the motor to clean the motor, shorten the distance between the stator and rotor, and effectively reduce dust.

The above is an appropriate measure to protect the cooling fan itself from dust. In fact, it is also a good method to install the dust screen in the fan. Due to the small demand for dust-proof cooling fans, most manufacturers do not have such wear-resistant fans, so install dust-proof screens without opening them.
