n air pre-heater is for pre-heating air supplied to one or more hot melt adhesive dispensing nozzles mounted on an adhesive supply manifold. Air is supplied from an air supply inlet on an outer portion of an outer heating member to an air supply outlet on an inner heating member having a heater therein. The outer heating member formed of laminated plates having one or more air flow paths, which include preferably a serpentine air flow path portion that increases the resistance time of the air therein. The air is supplied through the apparatus against a decreasing temperature gradient whereby heat is increasingly thermally isolated from the manifold to permit maintaining the pre-heating apparatus at a temperature different than a temperature of the manifold.
