What is a Fan Efficiency Grade (FEG)?

A Fan Efficiency Grade (FEG) is a numerical rating that classifies fans by their aerodynamic ability to convert mechanical shaft power, or impeller power in the case of a direct driven fan, to air power.  Essentially, it reflects fan energy efficiency, allowing engineers to more easily differentiate between fan models:

A more efficient fan model will have a higher FEG rating.  And FEGs apply to the efficiency of the fan only and not to the motor and drives.

FEG ratings can be applied to custom-built single fans and to series-produced fans manufactured in large quantities.
