1. A powder coating apparatus, comprising;
- a paint booth having a ceiling, two side walls, two end walls and a floor;
a first air jetting assembly coupled to upper portions of the two side walls, for causing air to flow downwards along the side walls; and
an air discharge assembly coupled to lower portions of the two side walls, for sucking the air flowing along the side walls and discharging the air out of the paint booth; and
wherein the first air jetting assembly comprises;
a first plate member which is a rectangular member having two long side portions and two short side portions, such that one of the two long side portions is fixed to the ceiling while the two short side portions are respectively fixed to the two end walls, and the other one of the two long side portions is positioned closer to the side wall than the one of the long side portions, whereby a first space is formed by the first plate member, the ceiling, the side walls and the end walls; and
a first air supply duct that supplies air from outside the paint booth into the first space, wherein a first jetting hole, through which the air supplied into the first space is jetted, is formed between the first plate member and each of the side walls.

Abstract
Air is continuously supplied into upper spaces via an air supply duct, during coating of an object to be coated in a paint booth, whereby the air is jetted through jetting holes and flows downwards along side walls. The air flowing downwards along the side walls is sucked into lower spaces, via clearances, and is discharged out of the paint booth via air exhaust ducts.
