Atlas Copco 1616-8285-90 is the ordering reference for the OIS K-43 oil-injected screw compressor element. On the physical air end, the nameplate carries part number 1616-8285-80 together with the OIS K-43 identification, so both numbers may appear when the element is checked against service records, quotations or the component already installed in the compressor.
As the main compression element, the OIS K-43 contains the screw rotor assembly within its dedicated housing and connects directly with the compressor drive, lubrication and compressed-air circuits. For this reason, identification should not rely on the general appearance of the air end alone. The ordering number 1616-8285-90, nameplate number 1616-8285-80 and OIS K-43 designation provide the specific references for confirming this element before replacement.

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.
