An axial fan is a type of fan that causes gas to flow through it in an axial direction, parallel to the shaft about which the blades rotate. The flow is axial at entry and exit. The fan is designed to produce a pressure difference, and hence force, to cause a flow through the fan. Factors which determine the performance of the fan include the ...

Un-balanced fans wobble and vibrate.

Another major problem in fans that are not balanced is longevity of the bearings (attached to the fan and shaft) is compromised.
