PROBLEM TO BE SOLVED: To solve a problem that there has been performed useless work in terms of energy efficiency since there is no idea for not using compressed air which is not cooled, and there is a necessity for performing control so that an air compressor and an after-cooler which use power should correspond to each other since they are not integrated with each other, and also it can be said that it is useless to connect the after-cooler large in the generation of drains and the other apparatus small in the generation of drains. SOLUTION: In this treatment method of drain water generated from the compressed air by an air tank 14 and a refrigerating air drier 30 of constituting a package type refrigerating air drier-mounted air compressor 1 for performing operating by a single power source, drain water D1 from the air tank 14 is sent out by an electromagnetic drain trap 40 together with the uncooled compressed air, and drain water D2 from the refrigerating air drier 30 is merged by a drain trap 50 at its downstream side.
