PROBLEM TO BE SOLVED: To reduce noise by minimizing the operating sound of a compressor body transmitted to the outside of a package box while maintaining the cooling efficiency of an apparatus stored in the package box by ventilation. SOLUTION: A compressor body 5, a motor 4 driving the compressor body 5, and an air tank 3 storing a compressed air compressed by the compressor body 5 are stored in the package body 1. An inlet 1a and outlets 1b and 1b are formed in the package box 1. A duct 7 exclusively used for intake capable of sucking air from two horizontal directions is installed at the inlet 1a, and a sound absorber 8 is fitted to the inside of the duct 7 exclusively used for intake. The outlets 1b and 1b are formed at the upper and lower sides of the duct 7 exclusively used for intake. When a flywheel 5c is rotated, outside air is sucked through the duct 7 exclusively used for intake and the inlet 1a, air-cools the compressor body 5 by its cool, and is discharged to the outside of the package box from the upper and lower outlets 1b and 1b.
