Abstract
A fan assembly includes an axial flow fan between an inlet stator and an outlet stator. The inlet stator has inlet stator blades which extend outwardly from an inner ring. Each inlet stator blade has a downstream edge which has a tangent which is oriented at a first variable angle with respect to a plane which is perpendicular to the fan axis. The first angle increases with increasing distance from the inner support ring. The outlet stator has a plurality of outlet stator blades which extend outwardly from a second inner ring. Each outlet stator blade has an upstream edge which has a tangent which is oriented at a second variable angle with respect to a plane which is perpendicular to the fan axis. The second angle decreases with increasing distance from the inner ring.
