Abstract

A paint delivery and application system including a color changer, at least two paint canisters and a paint applicator, a first pair of supply lines connected between the color changer and the paint canisters and a second pair of supply lines connecting the paint canisters and the paint applicator, wherein the paint canisters operate in tandem permitting delivery of a first paint to one of the paint canisters while a second paint canister is electrically isolated from the color changer and is delivering paint to the applicator. In one disclosed embodiment, the delivery line from the paint canisters to the applicator includes two pigs and solvent is delivered between the pigs, such that this system is self purging.
