The Atlas Copco 2989015800 is a genuine O.I.S. K-25 service-stage air end, cross-referenced with part number 1616646680 — the two numbers identify the same 116 kg assembly. This element is referenced in parts data for the GA30-45+50 VSD range, though we recommend confirming against your compressor’s nameplate part number before ordering, as we could not fully cross-verify this compatibility across independent sources.
At 116 kg, this element sits between the compact F-series elements (17-20 kg) and the large GA90+ class elements (360kg+) we also supply — consistent with a mid-capacity, belt/direct-driven compressor application.
