PROBLEM TO BE SOLVED: To perform coating work in a coating booth while air pollution is prevented, the safety of the work is secured, and high quality is kept. SOLUTION: A suction chamber 6 is installed in the front part of the coating booth 3, an ejection chamber 9 is installed in the ceiling part 7, and an air feed chamber 10 is installed in the rear side upper part. When a circulating fan 57 installed in the suction chamber 6 is operated, a coating exhaust gas in the coating booth 3 is sucked into the suction chamber 6, a coating mist is removed by a mist removing filter 22, and organic solvent components are removed by an active carbon filter 50a. After that, active carbon dust is removed by a dust removing filter 56. Cleaned air is supplied to the ejection chamber 9 to be ejected downward into the coating booth 3 through an ejection filter 72. Outside air sucked by the operation of an air feed fan 82 installed in the air feed chamber 10 is ejected downward on the rear part side in the coating booth 3 through an air feed filter 81, and the excess coating mist generated on the rear part side is moved downward.
