A semiconductor manufacturing apparatus ventilating system can reduce energy consumption with respect to air-conditioning and a power spent for transporting air in a clean room by minimizing an amount of circulating air in a clean room. The clean room air, which is supplied to the clean room, is introduced into an air circulating system including the semiconductor manufacturing apparatus. The air circulating system is separated from an atmosphere in the clean room. The clean room air in the air circulating system is circulated within the air circulating system.
