1. An air moving device comprising:
a housing having an air inlet at a first end and an air outlet at a second end spaced from said first end with an air flow passage between said first and second ends, wherein the air flow passage has a cross sectional area that decreases from the air inlet to the air outlet to form a nozzle,
an impeller mounted in said housing closer to the air inlet than the air outlet, the impeller having a plurality of blades, each of the plurality of blades having an upstream edge and a spaced downstream edge,
a plurality of spaced, radially extending air guide vanes that extend longitudinally in the housing between the impeller and the air outlet; and
a grill and support assembly which defines a surface which supports the housing, such that the first end of the housing is positioned on a first side of the grill and support assembly and the second end of the housing is positioned on a second side of the grill and support assembly, the grill and support assembly defining a plurality of openings to permit air to flow through the plurality of openings around an outside of the housing, wherein each opening of the plurality of openings is positioned between convexly curved grill fins.
