Abstract: An industrial washing machine for manufactured parts includes a cabinet with a support mounted in it to hold parts to be washed at any desired height to facilitate loading and unloading, and to permit the machine to hold parts of different sizes and shapes to increase its utility. A manifold in the cabinet sprays hot washing liquid on the parts, and includes a centrally located port so washing liquid can be sprayed longitudinally along the axis of rotation, and radially outwardly from the center of the cabinet. The load of parts being washed is supported by the manifold. A door with an adjustable latch seals the washer during the washing operation. A filtration system removes contaminants from the washing liquid, which is recycled for additional cleaning of parts. A pressure relief valve and a vent permit gas to flow from the cabinet when the pressure in the cabinet is at one value, and impedes flow of gas from the cabinet when the pressure is at a lower value.
