When the air pressure in the tank part (5) drops from the restart set pressure value to or below the minimum set pressure value, the control circuit part (2) operates the electric motor (3b) at the predetermined revolving speed or a revolving speed lower than N2 until the air pressure in the tank part (5) reaches the maximum set pressure value.
