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 completely, because there is enough space
For ultra-thin miniature fans below 10mm, such as 20*20*6, 30*30*7mm and other specifications, their thickness is only 7mm. If you need to add a dustproof inside the fan blade and outside the motor Cover, it is really not easy to seal the motor completely, because the space is too small
In view of the dust-proof problem of the cooling fan, it is recommended that customers use our ultra-thin double-ball cooling fan. The balls are originally imported from Japan, and dust is not easy to enter. As long as there is no dust, coils, and PCB accessories in the bearing, dust will have little effect. Yes, so it has strong dust-proof ability and can ensure that the life of the cooling fan is more than twice as long as that of the cooling fan with oil bearing.
