Currently, DC brushless fan are applied field more and more range of customer¡¯s applications from CPU,
sever, power supply to telecom, PV application for outdoor or relatively austere environment.
Waterproof and dustproof fan are indeed of required under these conditions as following trend . |

Old type waterproof Fan |
1. |
Coating Process (Vacuum Deposition): stator and PCB coating process are high risky for components,
and lower corrosion-resistant |
2. |
Glues Pouring Process﹕ Fully glues feed in HUB within stator and PCB, this process is complicated
and bubble remain in colloid was worse isolation |
