ABSTRACT:
A fan support for supporting a fan in an elevated position and oscillating the fan about the support. The device includes an adjustable column supported in a vertical position by a plurality of legs. A fan support channel is pivotally mounted to a top end of the column and is operable to receive and support a fan, such as a box shaped fan, thereon. An oscillation device is provided to effect a repetitive pivoting movement of the support channel in the horizontal plane, and a thermostat for controlling operation of both the fan and the oscillation device is also included.
