Abstract: An airflow assembly, includes a plenum, a barrel, a fan support, a fan assembly, and a plurality of ribs. The plenum includes an opening structure defining a plenum opening. The barrel extends in a downstream direction from the opening structure, and defines a barrel space and a downstream edge. The fan support is at least partially positioned within the barrel space. The fan assembly is supported by the fan support and includes (i) a motor and (ii) a blade assembly configured to rotate about an axis. Each of the ribs extends between (i) the opening structure or the barrel and (ii) the fan support. The downstream direction is parallel to the axis. An upstream direction is opposite of the downstream direction and parallel to the axis. A plane intersects the axis and is perpendicular to the axis.

Abstract: A fan assembly that includes a fan having a fan hub and motor having a drive shaft and a drive member coupled to the drive shaft for rotation with the drive shaft. The fan hub includes an inner face and an outer face. The drive member contacts the inner face of the fan hub to define a plurality of discrete drive member contact zones between the drive member and the inner face of the fan hub. A clip engages the drive shaft and the outer face of the fan hub to couple the fan to the drive shaft. The clip contacts the outer face of the fan hub to define a plurality of discrete clip contact zones between the clip and the outer face of the fan hub. The plurality of drive member contact zones are generally aligned with the plurality of clip contact zones.
