A method for manufacturing an air compressor assembly including, between a tank
welding step and a final assembling step, a step of submerging a welded tank into
a dip tank that contains cooling liquid treated with a corrosion inhibitor. In
a preferred embodiment, in the submerging step, all air access ports of the welded
tank are open to allow the cooling liquid to coat both the inside and outside surfaces
of the air tank to maximize corrosion inhibitor protection and increase tank cooling
rate. The method for manufacturing an air compressor assembly according to the
present invention may be used in manufacturing air compressor assemblies in various styles.
