PROBLEM TO BE SOLVED: To provide a method for restarting a compressor at power interruption, shortening a restarting time for the compressor during the power interruption and improving the work efficiency of each apparatus using the compressor. SOLUTION: A pressure switch 1 (PS) activated only during the power interruption is provided in the compressed air path of the compressor 2. When an air pressure value in the path reaches 0.3 MPa, a restarting instruction is outputted to a motor 3 by the pressure switch 1 through a control section 18. Thereby, a time required for restarting the compressor in the past is remarkably shortened. COPYRIGHT: (C)2009,JPO&INPIT
