Abstract: A device for supplying a mixture of fluids (cleaning agent and air) to a color bank in a paint finishing system for the purpose of removing paint residue, thereby flushing out the system. The device, may be supplied with any number and types of fluids. The device comprises valves for the purpose of activating fluid flow, an overall shape that allows for easing mounting in an existing color changer rack system or as an independent device, and a screen plate located in the path of the fluids, for the purpose of mixing the fluids. A screen plate and discharge port is configured into the body of the device to deliver the cleaning fluid mixture in a turbulent swirling movement to the next section of the color bank or to the next item to be cleaned. A method of cleaning a color bank using the device is disclosed.

Abstract: A rotary atomizer for a coating apparatus has a bell shaped body, e.g., a bell cup, having a cavity and a detachable flow control device, e.g., face cover, that substantially closes a portion of the cavity. The two-piece construction eases maintenance, such as cleaning, and the manufacturability since the inside the bell cup is easily accessible from the mouth (wider opening) of the bell cup. After the face cover is detached, it can be reused or discarded for a new one. The bell cup further has cleaning channels that can direct cleaning agent directly onto the outer surface of the bell cup, without any reservoir or the like that can accumulate coating material.
