ABSTRACT OF THE DISCLOSURE The present invention relates to a fan unit which may be used either as a floor fan or as a window mounted fan. When used as a floor fan, the frame is supported on the floor and the motor driven fan unit, which is pivotally connected to the frame, may be rotated to provide air flow in any direction. The fan unit comprises rises an open frame having a motor driven fan connected to the rear portion thereof, a pair of protruding pins on the frame front portion which engage the window on the outside thereof, and a second pair of protruding pins on the frame front portion which engage the window frame on the inside thereof. The motor driven fan is suspended in this manner inwardly away from the window opening such that the cantilever effect produced thereby pulls the first pins inwardly against the window and pushes the second pins outwardly against the window frame. The frame of the fan diverges slightly in the vertical direction so that it is, in effect, wedged into the window opening and makes it more diffi- cult to remove accidentally and strengthens the frame. The unit is easily adapted for use with a horizontally sliding window by attaching a pair of removable laterally extending brackets.
