An air suspension system includes an air tank, an air drier, a compressor, and an air spring, which are sequentially provided in a first line. The air suspension system further includes a second line, a third line, an intake line, and a discharge line, which are connected to the first line. The first line, the second line and the third lines can be switched by a 4-port/2-position solenoid valve, and the first line is selectively connected to the intake line by a 3-port/2-position solenoid valve.
