Abstract: 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.

Abstract: An air compressor assembly having an air tank which, during air usage, continuously discharges condensate accumulated in the air tank into the compressed air being released. The air tank has an air outlet port at its wall, through which compressed air and condensate are released for use in air powered tools during air usage.

Abstract: An air compressor assembly having an unpainted air tank that is enclosed in a shroud. The air tank may be made of metal, plastic, or the like. In a preferred embodiment, the shroud is made of plastic. The shroud may also be made of metal or the like. The air compressor assembly according to the present invention may be formed in various styles, including a portable type air compressor assembly, a “pancake” type air compressor assembly, a “hot-dog” type air compressor assembly, a vertical “hot-dog” type air compressor assembly, a vertical stationary type air compressor assembly, a “double hot-dog” type air compressor assembly, and the like.
