1. An air moving device comprising:
- a housing having a first end, a second end, and a longitudinal axis extending between the first end and the second end;
an impeller rotatably mounted within the housing adjacent the first end of the housing, the impeller having one or more rotor blades capable of directing a volume of air toward the second end of the housing, the impeller configured to rotate about a rotational axis;
a nozzle connected to the housing between the impeller and the second end of the housing, the nozzle having an inlet and an outlet, the outlet having an oblong cross-section, the oblong cross-section having a major axis and a minor axis, wherein a cross-sectional area of the outlet of the nozzle is less than a cross-sectional area of the inlet of the nozzle; and
one or more stator vanes positioned within the nozzle, at least one of the stator vanes having a first end at or adjacent to the inlet of the nozzle and a second end at or adjacent to the outlet of the nozzle, the first end of the at least one stator vane positioned closer to the longitudinal axis of the housing than the second end of the at least one stator vane;
wherein a cross-sectional shape of the inlet of the nozzle is different from the oblong cross-section of the outlet of the nozzle.

Abstract
An air moving device includes a housing member, an impeller assembly, and a nozzle assembly. The nozzle assembly can include one or more angled vanes set an angle with respect to a central axis of the air moving device. The air moving device can output a column of moving air having an oblong and/or rectangular cross-section. A dispersion pattern of the column of moving air upon the floor of an enclosure in which the air moving device is installed can have an oblong and/or rectangular shape. The dimensions of the dispersion pattern may be varied by moving the air moving device toward or away from the floor, and/or by changing the angles of the stator vanes within the nozzle assembly.

12. An air moving device comprising:
-
an impeller assembly having; an inlet end; an outlet end; and an impeller positioned between the inlet end and the outlet end and having a first impeller blade and a second impeller blade, the impeller having an axis of rotation wherein rotation of the first and second impeller blades about the axis of rotation draws air into the inlet end of the impeller assembly and pushes air out of the outlet end of the impeller assembly; and a nozzle assembly positioned downstream from the outlet end of the impeller assembly, the nozzle assembly having; a nozzle housing having a nozzle inlet and a nozzle outlet positioned farther from the impeller assembly than the nozzle inlet, wherein a cross-sectional area of the nozzle outlet is less than a cross-sectional area of the nozzle inlet, and the nozzle housing defining a nozzle interior between the nozzle inlet and the nozzle outlet; a nozzle axis; a first stator vane positioned at least partially within the nozzle interior, the first stator vane having an upstream end and a downstream end; and a second stator vane positioned at least partially within the nozzle interior, the second stator vane having an upstream end and a downstream end; wherein the upstream end of the first stator vane is bent at a first angle with respect to the nozzle axis, wherein the upstream end of the second stator vane is bent at a second end with respect to the nozzle axis, and wherein first angle is less than the second angle. - View Dependent Claims (13, 14, 15, 16, 17, 18, 19, 20, 21)
