Abstract
A method of operating an air-feed type spray booth, which comprises forcively feeding an air from an air conditioner to the inside of a spray booth by a feed fan, drawing the air in the spray booth together with painting mists, or the likes by an exhaust fan through the floor of the booth and then exhausting them externally, while the direction of air streams, if any, flowing inwardly and/or outwardly of the booth through the inlet and/or outlet thereof is detected and the exhaust flow rate of the exhaust fan and/or the feed flow rate of the feed fan is variably controlled depending on the detected direction of the air streams, so as to inhibit the air stream from flowing inwardly and/or outwardly throught inlet and/or outlet.
