Abstract
A booth of a powder coating system is designed for quick color changes. The booth includes a bottom wall supported above a floor. An inner space of the booth is defined above the bottom wall and an equipment-receiving space is defined beneath the bottom wall. The bottom wall has an opening providing communication between the inner space and the equipment-receiving space. The booth is adapted to receive a powder-recovery module beneath the bottom wall in the equipment-receiving space.
