1. A compressor comprising:
a housing forming a profile;
a compressor body to compress gas;
a motor to drive the compressor body;
a control board to control the motor; and
a tank to store the gas outputted from the compressor body,
wherein the housing has:
a machine chamber storing the compressor body and the motor,
a B-chamber having piping to connect the compressor body with the tank,
an A-chamber storing the tank,
an A-partition separating the machine chamber from the A-chamber and B-chamber,
a B-partition between the A-chamber and the B-chamber, and
an exhaust duct used to exhaust air taken into the housing through a first air intake port in a rear plate of the housing and having cooled the compressor body,
wherein the A-chamber has a second air intake port to introduce ambient air, the second air intake port is at a position in the rear plate near a bottom plate of the housing,
wherein a first flow path is created by moving a portion of the ambient air from the second air intake port, through the A-chamber, past the tank, and out of the housing,
wherein the A-partition has an A-vent as a hole to communicate between the machine chamber and the A-chamber,
wherein a suction port of the compressor body is located in vicinity to the A-vent, and
wherein a portion of the A-partition is included in components defining the exhaust duct.
