The present invention comprises a portable ventilation system which can be incorporated into caps, hats or other conventional headgear. An aperture is formed in the brim or front section of a hat or cap which is adapted to receive the body of the ventilating apparatus. A direct current motor is installed at the center of the mounted body, the shaft of the motor being directly coupled to a multiple bladed impeller. A directional visor is mounted below the impeller and in juxtaposition to the user's face for directing the flow of air resulting from rotation of the impeller. The DC motor is powered by a portable battery pack. Interconnection between the motor source for the present invention and the battery pack allows the hat or cap upon which the present invention is mounted to be removed.
