Patent ID: 8137064

Claim:
A fan apparatus comprising: an impeller; a motor arranged to rotate with respect to a central axis in a concentric manner with the impeller; a plurality of stator blades arranged in a substantially radial direction opposite from the impeller in an axial direction; and a support portion connected to the stator blades; wherein each of the stator blades includes a curved portion extending in the radial direction; a direction in which each stator blade extends changes at the curved portion thereof along a hypothetical surface that is substantially perpendicular to the axial direction such that a first portion of each stator blade arranged adjacent to the support portion extends in a different circumferential direction than that of a second portion of each stator blade arranged adjacent to the curved portion; and the first portion of each stator blade veers towards a direction that is opposite to a rotational direction of the impeller with respect to the central axis.
