A multi-stage gas compressing apparatus is provided to simplify an operation control system, to reduce the cost, and improve safety. A multi-stage gas compressing apparatus comprises a first gas compressor(1) compressing the gas; a second gas compressor(3) which is connected to the first gas compressor through a conduit(2) and further compresses the gas compressed by the first gas compressor; a storage tank(5) which is connected to the second gas compressor and keeps the gas compacted by the second gas compressor; a detector which is connected to the storage tank, detects a first upper pressure limit or a first lower pressure limit of the gas within the storage tank and generates the signal; and a control device(7) connected to the detector, the first gas compressor and the second gas compressor. The first gas compressor and the second gas compressor are start and stop at a time according to the signal transmitted to the control device from the detector.
