The Atlas Copco 1616-5851-81 is a genuine O.F.S. G-21 air end, referenced for ZR55-75-90 oil-free compressor platform. At 53 kg, it’s the lightest oil-free element we currently stock — noticeably smaller than the I-41 (119 kg) or M-21 (265 kg) in the same O.F.S. range, consistent with the smaller-frame VSD units it serves.
This part is currently in stock, unlike most of the larger oil-free elements in our range, which are typically supplied on request.
