Abstract
A centrifugal fan assembly including a housing having a lower surface and a parallel inlet wall that defines an inlet opening. A shaft is supported by the housing for rotating about an axis. A plurality of fan blades are disposed about the shaft and extend radially from the axis for drawing air axially into the fan blades and blowing air radially outwardly. The housing defines a scroll wall that spirals about the axis and defines an outlet air passage that extends substantially tangentially to the axis. The fan blades include extensions that extend through the inlet opening and outside of the inlet wall.
