Abstract

Implementations of an enhanced axial air mover system address various issues such as drying performance, transportability, storage, use, and assembly. Some implementations include ergonomic positioning of a carrying handle relative to positioning of a fan-assembly to make the system easier to carry. Enclosures with variable diameter profiles increase air flow performance. A floor edge allows for flush positioning of the air mover'"'"'s outlet to improve flow of air. Various supports and engagement members allow for horizontal and/or vertical engagement of a plurality of the air movers for storage or increased air moving capacity for a given application. An alignment guide assists with positioning of the air mover with respect to a room wall to enhance air flow within the room. A cord retaining system provides an enhanced approach for securing the air mover'"'"'s electrical cord. Grill guards have slotted ends to assist with assembly of the air mover.

Claims

1. An air mover system comprising:

a fan assembly including a propeller and a motor, the propeller coupled to the motor; and

a housing assembly including an enclosure, the enclosure having an interior bounded by an inlet and an outlet, the fan assembly positioned within the interior, the enclosure having a variable diameter including a first diameter at the inlet, a second diameter at the outlet and a third diameter at a mid-point on a first dimension extending from the inlet and outlet, the difference between the first diameter and the third diameter is at least five percent of the first diameter.

2. The air mover system of claim 5 wherein the difference between the first diameter and the third diameter is at least ten percent of the first diameter.
