ABSTRACT:
The device for creating a curtain of air across the face is a headset with a fan mounted thereon. The outlet of the fan has flexible tubing or cowling which allows for control of both direction and cross section of a curtain of air that crosses the face. The curtain of air prevents airborne particles and chemicals from making contact with the face.
