ABSTRACT:
A personal body ventilation system includes a battery powered blower for providing air under pressure to the interior of a disposable garment formed by an inner air impervious layer and an outer air impervious layer. Porous-to-air open celled foam is incorporated into the garment at areas where cooling is desired and provides porous surfaces adjacent the body of the wearer from which the air under pressure in the interior of the garment may be directed against the body of the wearer. The system includes a filter arrangement in which a filter incorporated in the garment filters the ambient air prior to being drawn into the blower. The blower, the ouput of which is coupled to the garment in the rear by an elliptical connection, includes miniature radial turbine fans operating under a variable speed control. The circulated air may be heated or cooled or treated in various manners such as filtering or humidifying/dehumidifying to meet the requirements of the specific user environment.
