Abstract
The fan includes a fan frame, blades positioned inside the fan frame, a grill frame on a side of the fan frame, a centerline of the grill frame traversing through a midpoint of the grill frame, a first motor configured to rotate the blades to produce an air flow in a first direction through the grill frame, the first direction being parallel to a centerline of the grill frame, a second motor configured to rotate the grill frame within the fan frame, a plurality of louvers affixed within the grill frame, the plurality of louvers including a first subset of louvers and a second subset of louvers, the first subset of louvers possessing no offset angle relative an angle of the centerline, each one of the second subset of louvers being angled toward a first side of the grill frame due to the at least one first offset angle.
