Abstract: In a multistage split compressor wherein the low pressure compressor has a plurality of stages on one rotor and the high pressure compressor has a plurality of stages on another rotor, the low pressure compressor is removable as a unit from the high pressure compressor by making the intermediate case in two pieces, one integral with the low pressure compressor case with an associated bearing for the low pressure rotor and the other integral with the high pressure compressor case also with an associated bearing for the high pressure rotor. By having these two pieces removably secured together, the associated compressor cases may be separated by removal of the attachment devices holding the cases together, and each case carries with it the associated bearing for the enclosed rotor.
