Abstract
Exhaust components of a coating apparatus can be cleaned to remove coating material therein and/or can be periodically treated so as to prevent the buildup of coating material with exhaust components. Moreover, coating materials and cleaning liquids can be separated from the exhaust stream and collected to a drain. An exhaust manifold includes an integral rinsing mechanism and a fluid separator. Rinsing can be controlled automatically or manually.
