PROBLEM TO BE SOLVED: To improve the rate of operation of a compressor 1 and a pneumatic power tool in a system formed of at least two kinds of pneumatic power tools having a different driving maximum pressure and the compressor 1 for supplying the compressed air to the pneumatic power tools by taking at least two kinds of compressed air having a different maximum pressure from one air tank and controlling the pressure of the compressed air to be supplied to each pneumatic power tool at the driving maximum pressure of each pneumatic power tool or less. SOLUTION: The compressor 1 is provided with at least two kinds of pressure reduction valves 4 and 5 having a different maximum pressure of the compressed air to be taken out, and fluid coupling parts for connecting hoses 6, 7 connected to each pressure reduction valve 4, 5 and the pressure reduction valves 4, 5 to each other and fluid coupling parts for connecting the hoses 6, 7 connected to the pneumatic power tools 2, 3 and the pneumatic power tools 2, 3 to each other are formed without compatibility.
