Zusammenfassung:A spray applicator is operable in a spray state, during which the applicator emits a plural component material formed within a mix chamber of the spray application, and a purge state, during which the spray applicator emits compressed air from the mix chamber. First and second portions of the purge air are provided to the mix chamber through separate flowpaths and combine within the mix chamber. Only one of the portions of purge air is routed through a dosing chamber to entrain solvent and carry the solvent to the mix chamber. The solvent assists in clearing residue from the mix chamber.
