An air mover assembly comprises: an impeller which has an outer diameter and a rotary shaft; a motor which drives the impeller; an air mover housing which has one or more air inlets for receiving air when the impeller is rotated and one or more air outlets and surrounds at least a part of the impeller and the motor; and an air mover inlet interface which is adjacent to the air inlets and has a height, a wall having a curvature according to at least a part of the height of an air mover inlet interface expanded outward in the flowing direction of air, and an outer diameter smaller than the outer diameter of the impeller. Therefore, the present invention reduces aerodynamic noise by allowing air to flow toward the impeller. |
