Vehicle powder coating system

An apparatus for applying powder coating material onto objects, comprising:

• a spray booth having a ceiling, floor, and opposed side walls defining an interior which provides a controlled area for the application of powder coating material onto objects moving therethrough;
• a powder collector located immediately adjacent said spray booth for collecting oversprayed powder from said interior thereof, said powder collector including:
• (i) powder collection units extending along substantially the length of said spray booth, each of said powder collection units having a powder collection chamber for receiving oversprayed powder from said interior of said spray booth;
• (ii) a plurality of clean air chambers, each of said clean air chambers being associated with one or more of said powder collection units, each of said clean air chambers having an interior which is isolated from the oversprayed powder entering said powder collection chamber;
• (iii) filters located within said powder collector connected to said clean air chambers for collecting oversprayed powder thereon to form clean air which is introduced into said clean air chambers;
• a number of exhaust units, each connected to a plurality of filters, for creating a negative pressure within said powder collector to draw air entrained powder coating material from said spray booth into said powder collector,
• wherein each of said exhaust units includes a respective exhaust conduit and an exhaust fan, said exhaust conduit being connected by a plurality of ducts to said clean air chambers, each of said ducts connected to one said clean air chamber, said exhaust fans being operative to create a negative pressure within said exhaust conduits, said plurality of ducts, said clean air chambers and said filters to draw oversprayed powder to said powder collector.
