The Atlas Copco 1616757591 is a genuine OIS J-50 service air end, used across both the C77 and C90 compressor platforms. At 61 kg, it sits in the mid-range of Atlas Copco’s OIS series — smaller than the large stationary GA90+ class elements, but built for the same continuous-duty standards.
A single J-50 element serves both the C77 and C90 platforms because the air end itself has no fixed flow or pressure rating — actual output depends on the gear ratio and drive configuration of the host compressor. This is why the same part number can correctly fit two different compressor series: the element is identical, but the surrounding drivetrain determines its working capacity.
