An air management system of a vehicle, the air management system comprising:

• an air compressor configured to generate compressed air;
• an air processing device fluidly connected to the air compressor and configured to purify and/or dehumidify the compressed air discharged from the air compressor;
• a first air tank fluidly connected to the air processing device and configured to store the compressed air passing through the air processing device;
• an air brake device fluidly connected to the first air tank and configured to perform a braking operation of the vehicle using the compressed air stored in the first air tank;
• a second air tank fluidly connected to the air brake device and configured to store exhausted air that is discharged from the air brake device and that is used for the braking operation;
• a solenoid valve connected to each of the second air tank and the air processing device through pipes and configured to control movement of the exhausted air between the second air tank and the air processing device;
• and
• a control unit in communication with the solenoid valve and configured to control opening or closing of the solenoid valve.
