Abstract
Advertising fan, essentially characterized by comprising three discs, mounted concentrically with respect to the protruding shaft of the engine, whose discs, one of them, the rear is fixed and independent of the motor shaft and is the one that has the advertising element; the second disc, intermediate, also independent of the rotating shaft of the motor, has openings as well as capriciously colored patterns, capable of producing, with the rotation of the front disc, whimsical optical effects, and the third disc, front, mounted directly on the front end of the motor projecting shaft has equally spaced openings to act as a Maltese cross, as well as portions curved at its periphery to increase the fan action.
