Atlas Copco 1616-7540-90 is an OIS Q-05 / C242 compressor stage for oil-injected screw compressor systems. The OIS Q-05 / C242 designation identifies the specific compression stage, while the two part-number references are useful when matching the component with Atlas Copco service and procurement records.
For physical identification, the corresponding air-end reference is 1616-7540-80, while 1616-7540-90 is used as the ordering or system reference. Both numbers should therefore be considered when checking an existing unit, particularly when the number on the air-end nameplate differs from the number shown in a parts or purchasing system.
As a complete compressor stage, identification should not rely on the part number alone when replacing an installed unit. The OIS Q-05 / C242 code, compressor model and serial number, and the physical configuration of the existing stage should be checked before ordering to confirm the correct air-end assembly.

Always confirm against your compressor’s nameplate part number before ordering, as Atlas Copco may use this element across multiple production batches or regional variants.
Signs Your Air End Needs Replacement
Consider replacing the air end if you notice:
– A gradual drop in discharge pressure or airflow at the same load
– Rising discharge air or oil temperature without a clear cause
– Increased vibration or unusual noise from the compression chamber
– Rising energy consumption for the same output over time
These symptoms typically point to internal wear — rotor clearance, bearing wear, or seal degradation — rather than a component elsewhere in the airend package.
