ABSTRACT:
Apparatus for powder coating various types of parts using different powder coating techniques. The apparatus includes a powder coating hood in which the coating operation takes place and a powder collection booth connected to the hood for drawing air and excess powder out of the hood. An air circulation system is provided in the collection booth for drawing excess air and powder from the hood. An air flow regulator is provided to adjust the draw of air and powder between low and high amounts. A low amount is, for example, useful for electrostatic fluidized bed coating, while a higher amount may be useful for spray coating techniques.
