A fan assembly comprising a fan, a stationary airflow directing device and a support inner ring. The fan has a hub portion and a plurality of fan blades. Each of the fan blades has a root region and a tip region. The root regions of each fan blade are secured to the hub portion wherein the fan blades extend substantially radially of a fan rotational axis. The airflow directing device has a plurality of stator blades extending radially about the support inner ring. The stator blades receive air flow from the fan and divert the airflow. The surface area of the stator blades is substantially less than the surface area of the fan blades. Each stator blade has a planar surface and a curved surface opposing the planar surface. The planar surface is disposed such that rotational components of air flow from the fan are incident on the planar surface. |
