Application Notes How Do I Properly Size a Fan?

the fan sizing process. Once the fan is sized the ducting arrangement interfacing to the fan can change performance. In order for the fan to achieve its rated performance the inlet air flow must be fully developed, symmetrical, and swirl free. For a centrifugal fan a minimum of one inlet diameter of free area around the fan inlet is recommended.
