Fan with first subset of louvers and second subset of louvers

A fan, comprising:

• a fan frame;
• blades positioned inside the fan frame;
• a grill frame on a side of the fan frame, the grill frame existing in a vertical plane, a centerline of the grill frame traversing through a midpoint of the grill frame and being perpendicular to the vertical plane, the grill frame having a first width;
• 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 in one of a clock-wise or a counter-clockwise direction within the fan frame;
• and
• 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, each of the plurality of louvers being substantially flat and having a longitudinal length spanning the first width, the plurality of louvers being parallel to each other, the first subset of louvers possessing no offset angle relative an angle of the centerline, the first subset of louvers being directly adjacent to each other without intervening louvers being in the first subset of louvers,
• the second subset of louvers having at least one first offset angle that deviates from the 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, a first louver, of the second subset of louvers, being on a distal-most end of the grill frame on the first side, the first louver having a second offset angle that flares the first louver in an outward direction, the second offset angle being a greatest offset angle relative to the other louvers of the plurality of louvers.
