Visit at - http://techflow.net/axial_fans.html - know about Axial Fans features, factors, how they operate and industrial applications. Basic principle of operation of the axial fan is that the direction of air flow is parallel to the rotor shaft. The blades of the fans force air linearly to the shaft. They are known to create a high flow rate, and they are able to achieve a bigger volume of air flow. In their operation, the air movements they create is of lower pressure and generally require lower power input for operation.
