Abstract
This invention is directed to a protective headgear system which includes a relatively light weight, substantially rigid, headgear structure which may include an internal, adjustable headband. The system includes at least one filter which is attachable to the headgear structure to cover the structure and a filter protector mounted thereon. A fan mechanism is mounted on the headgear structure to draw air into the headgear structure through the filter means. A power supply selectively powers the fan. A facial shield is attachable to the headgear structure to cover the face of the wearer to maintain non-contaminating conditions relative to the wearer. A flexible cuff or hood is attachable to the facial shield to enclose the lower opening of the lens and provides protection for the wearer through which air can be exhausted.
