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.
