PURPOSE:To miniaturize each air supply apparatus to the best possible extent and to avoid the loss of an installation space and operation cost, by dividing a part of functions possessed by each air supply apparatus while functionating the divided functions in intensive manner. CONSTITUTION:Plural lines of painting booths 6 are formed along with conveyor lines of objects to be painted in the downstair chamber of a two-storied building while a plurality of blowers 10 each sending air to each booth 6 through an air sending duct 7 are provided in the upstair chamber 1 thereof and a plurality of make-up air generators 9 are provided therein. In addition, a make-up air distributor 20 connected to the side of the air outlet 9a of each air generator 9 and having an emitting port 20a in the vicinity of the suction port 10a of each blower 10 is provided to form the internal space of the upstair chamber 1 into one common-use air supply chamber. By this mechanism, the dust removing and humidifying functions of an air supply apparatus can be used in common by a single dust removing filter and a single humidifier and the air sending amount of the air generators is reduced to only 1/2 on the basis of the total air feeding amount of the blowers 10.
