PURPOSE: An air supply controller for the air instrument test is provided to test the performance of the air instruments by operating the air instruments repeatedly. CONSTITUTION: An air supply controller for the air instrument test comprises a case, a pressure control unit(20), a solenoid valve(30), a timer(35) and a check valve(40). The case comprises a cover for opening and closing an inside storage space. The pressure control unit is built in one side of the case. The pressure control unit controls the pressure of the air from an air generation unit. The solenoid valve controls the flow of the air and is connected to the pressure control unit. The timer establishes an operation time of the solenoid valve. The check valve prevents the counter flow of the air.
