20110068201 | BUILD-UP MINIMIZING SPRAY GUN TIP - The advantage of this construction is that the time between manual cleanings of the frontal area of the gun can be lengthened or eliminated. The spray gun utilizes high pressure air forced through thin openings and that surround the spray tip, to eliminate the eddies in the air flow around the frontal area of the spray gun. One concentric thin opening surrounds the spray tip and is directed parallel to the direction of spray. With a second concentric thin opening, the air is directed at an angle of about 55 degrees relative to the axis or direction of spray. | 03-24-2011 |
