The Atlas Copco 1616630581 is a genuine O.F.S. O-21 air end, part of the same oil-free screw (O.F.S.) family as the O.F.S. Q-21 we also supply, used across Atlas Copco’s ZR/ZT oil-free compressor platform. At 585 kg, it sits between the Q-21 (904 kg) and the mid-weight oil-free elements in this range — the “O-series” and “Q-series” designations correspond to different frame sizes within the same oil-free product line, not different generations.
Oil-free construction eliminates any risk of oil carryover into the compressed air stream — a hard requirement in industries like food and beverage, pharmaceuticals, and electronics manufacturing. Please confirm your compressor’s nameplate part number before ordering.
