Abstract
A gun flush box is controlled by a plural component proportioning unit. When a color change is desired, the operator places the spray gun in the flush box. When a new color is selected, the control system automatically triggers the gun and flushes the gun with solvent with the flush material safely routed to a waste container. The control system automatically triggers the gun to refill the lines with new color paint without using excess paint as it displaces the flush solvent. This system is also capable of working with two guns in operation.
