Self-cleaning powder coating booth

A self-cleaning powder coating booth comprising:

• a housing including a plurality of interconnected side walls, a top wall and bottom wall forming a powder coating chamber, said top wall being longitudinally slotted extending the length of said powder coating chamber;
• an exit conduit in communication with said powder coating chamber
• conveying means with a plurality of depending holders extendable through said top wall and being movable through said powder coating chamber along a path of travel to hold items to be coated;
• powder dispensing means extendable into said powder coating chamber and operable to direct coating powder against said items to be coated;
• and,
• gas pressurized means connected to said housing and operable to direct pressurized gas into said powder coating chamber, said side walls having a plurality of first louvers formed thereon oriented- to direct pressurized gas parallel to sa:d side walls downwardly to said bottom wall, said top wall and said bottom wall also including a plurality of additional louvers formed thereon oriented to direct pressurized gas flowing through said additional louvers parallel to said to wall and said bottom wall to said exit conduit.
