PURPOSE:To facilitate assembly and maintenance and eliminate a compressor installation space by installing a compressor rotor casing directly onto an oil separator, thus removing a discharge casing and a discharge pipe. CONSTITUTION:At the edge of the shaft of each screw rotor 13, 13', each driving motor 2, 2' is incorporated onto the extension shaft of a male rotor supported by each bearing 14, 14' which receives a thrust and a radial load. The screw rotor 13, 13' and the motor 2, 2' are built into each casing 15, 15', and a semiclosed type compressor is formed. A plurality of semiclosed type compressors are directly installed onto a flange 17 formed onto the can trunk 16 of a horizontal- type oil separator 3. Therefore, a discharge casing and a discharge pipe can be removed, and assembly and maintenance can be facilitated, and construction and handling can be simplified, and the compressor installation space can be eliminated.
