PROBLEM TO BE SOLVED: To shorten the time taken to carry out coating process by leading discharged air to an air purification chamber side at the time when a push-pull type coating booth is used as a wet type solvent coating booth, and leading air to a duct side for recovering a powder coating material at the time when the coating booth is used as a powder coating booth. SOLUTION: At the time when a push-pull type coating booth 30 is used as a wet type solvent coating booth to coat an object work W to be coated, discharged air is discharged after being passed through an air purification chamber 50 by closing a powder coating material discharge route 30a by an air switching plate 68. At the time when the coating booth is used as a powder coating booth, air is discharged out of the powder coating material discharge port 30a after being passed through a duct 64 for recovering a powder coating material and a powder coating material dust collecting part by closing the lower end of the air purification chamber 50 by the air switching plate 68. Consequently, it is not required to separately install the wet type solvent coating booth and a powder coating booth, and the coating process can be shortened.
