1. A fan device, comprising:
a housing having a columnar shape and defining a central vertical axis, the housing having a base that is configured to sit on a surface;
an inlet configured to allow air into the housing at a side of the housing above the base;
an outlet formed around a circumference of the housing;
a fan positioned inside the housing between the inlet and the outlet, and configured to blow air toward the outlet;
a motor coupled to the fan and positioned below the fan;
a directional ducting member positioned inside the housing between the fan and the outlet to direct air blown by the fan through the outlet radially around the circumference of the housing, wherein the directional ducting member has a circular hyperboloid shape having a lower terminus positioned over a center of the fan, and wherein a distance between an inside of the housing and the directional ducting member decreases between the fan and the outlet such that an air velocity at the outlet is greater than an air velocity at the fan, wherein the lower terminus of the directional ducting member has a diameter that is narrower than a central cylindrical portion of the fan from which a plurality of fan blades extend; and
wherein the outlet is formed as a gap between the housing and the directional ducting member.
