<p>A hand-held blow gun is designed to help dental lab technology wash, rinse, and dry a prosthesis using one hand. High pressure air (100 p.s.i.) is needed to clean the work piece. Next a wash and finally an air dry process is needed. The vapor blaster is a one piece hand-held device having a single thumb actuated lever to progressively depress first an air valve and then a water valve. The invention is powered by a high pressure gas source from a gas reservoir (12) connected to a high pressure regulator (14). The high pressure regulator (14) is connected to the hand-held blow gun (8) and to a second low pressure regulator (3) connected to the remote second water bottle (2). An optional second water bottle is shown to select a cleaning solution cycle with T switches.</p> |
