PURPOSE: A control circuit, a ventilation apparatus, and a driving method thereof are provided to automatically maintain uniform static pressure and air quantity by sensing the change of the static pressure and air quantity. CONSTITUTION: A control circuit(200) comprises a power supply unit(210), a signal receiving unit(220), a data storage unit(230), and an operation processing unit(240). The power supply unit supplies driving power to a blower. The signal receiving unit receives RPM information measured from the blower. The data storage unit comprises information of a correspondence relation between a static pressure value and an air volume of the blower. The operation processing unit controls the blower based on the information of the blower.
