Can the micro cooling fan be dustproof?

For computer cooling fans, because they work for a long time every day, in order to extend the life of the cooling fans and reduce the interference of dust on the cooling fans, many customers require the cooling fans to be dust-proof. For some large-scale cooling fan manufacturers, such as the commonly used 8CM and 9CM cooling fans in computers, it is possible to do dust-proof and waterproof treatment. It is enough to seal the motor, because there is enough space for such as 10mm or less. Thin micro fans such as 20*20*6, 30*30*7mm and other specifications, their thickness is only so 7mm, if you want to add a dust cover in the fan blade, outside the motor, the motor is completely sealed , It’s really not easy, because the space is too small. Aiming at the dust-proof problem of the miniature cooling fan, the cooling fan manufacturer recommends that the customer use our ultra-thin double-ball cooling fan. The balls are imported from Japan and dust is not easy to enter. As long as there is no dust in the bearing , Coils, PCB accessories, dust has little effect, so it has a strong dust-proof ability, which can ensure that the life of the cooling fan is more than twice as long as that of the oil-bearing cooling fan.
