Abstract
A spray gun designed for utilization with low pressure and high volume air supplies to obtain high product transfer efficiencies. The spray gun is designed for connection to an air supply at two locations on the gun with one location providing non-pressure bleeding connection to the air supply and with the other allowing air to continually flow through the gun. The design of the gun is particularly sized with internal passages to allow high CFM and low PSI functions. An air cap assembly to control spray patterns for vertical, horizontal and circular sprays is arranged on the outlet end of the gun. The unit as designed eliminates the utilization and requirement of exterior valving and air control mechanisms.
