DC cooling fans are used in industrial applications. These fans find great applications in mechanical, electronic, and computer device cooling operations. A heated device can cause severe damage, therefore cooling is certainly preferred. However, dust can also cause unexpected interruption to industrial appliances that is why dust proof DC fans are preferred. In order to achieve 100% dust proof abilities of a DC cooling fan, its design and assembly have to be precise.
