PROBLEM TO BE SOLVED: To prevent drainage from accumulating in a drain pipe while applying a constitution in which a drainage tank is disposed in a soundproof box.SOLUTION: A soundproof box 10 accommodating components of a compressor 1, is composed of a frame 20 configuring a bottom portion of the soundproof box 10, and a bonnet 30 covering the frame 20, and a drainage separator 41 for collecting drainage generated in a compressed gas by cooling of an after-cooler 40, is disposed in a space (working machine chamber 10a) on the frame 20 covered by the bonnet 30. On the other hand, a drainage tank 50 for recovering the drainage collected by the drainage separator 41 is disposed in the soundproof box 10 in a state of accommodating at least its bottom portion in the frame 20, and an inlet 51 of the drainage tank 50 communicated with a drain discharge port 41a through a drain pipe 42, is disposed at a lower position with respect to the drainage discharge port 41a of the drainage separator 41.SELECTED DRAWING: Figure 3 |
