How to choose the right fan for your application

There are numerous types of air moving products including axial, propeller, and tubeaxial fans. Other air movers consist of impellers and blowers (centrifugal & crossflow). Which one is right for your application?


In thermal management, fans are classified as objects that forces air at a volumetric rate to cool certain devices, like a microprocessor.


There are numerous types of air moving products including axial, propeller, and tubeaxial fans. Other air movers consist of impellers and blowers (centrifugal & crossflow).


Fans, impellers, and blowers could be distinguished by their size, shape, but more importantly, the flow of air (measured in CFM) given the static air pressure.


A fan can basically have a high output of CFM, but at a lower level of air pressure, whereas blowers and impellers move smaller amounts of air at a greater level of pressure.


This paper from DAU Components explains how to make the right choice.
