The Atlas Copco 1616590481 is a genuine O.F.S. M-21 air end — referenced as a high-pressure (HP) element for the ZR4LP, ZR6, and ZR900VSD oil-free compressor platform. This distinguishes it from the standard O.F.S. O-21 and Q-21 elements we also supply: those serve general oil-free duty, while the M-21’s HP designation points to applications requiring elevated discharge pressure rather than standard plant air.
At 265 kg, it sits between the O-21 (585 kg) and lighter oil-free elements. Please confirm your compressor’s nameplate part number before ordering — the ZR4LP/ZR6/ZR900VSD reference comes from third-party parts data rather than an Atlas Copco published compatibility chart, so exact model confirmation still matters.
