Atlas Copco Rotair Plus 4L – 1630 1450 04

The Atlas Copco Rotair Plus 4L (part no. 1630-1450-04) is the same premium rotor lubricant as the 18L version we also supply (part no. 1630-1450-18), formulated for oil-injected screw air compressors. The 4L can suits smaller reservoirs, occasional top-ups, or keeping a spare on hand — the 18L drum is more cost-effective for full service changes.

As with any oil-injected screw compressor lubricant, confirming your compressor’s exact model and maintenance manual specification before ordering is the most reliable way to ensure fit.

Why Genuine Lubricant Matters

Genuine Atlas Copco lubricants are formulated with specific additive packages for oxidation stability, and are tested for compatibility with the seal and gasket materials used in Atlas Copco air ends.Non-genuine or off-spec oils can shorten air end service life and may affect manufacturer warranty terms —this is one area where the cost difference rarely justifies the risk on a component as critical as the air end.

Flushing When Changing Oil Type

Do You Need to Flush the System?

If you’re switching between oil types (e.g.,mineral to synthetic,or between different synthetic chemistries),a system flush is generally recommended to remove residual oil and prevent cross-contamination.Continuing to top up with a different oil type without flushing can gradually degrade lubrication performance.

Common Questions

We recommend against mixing different oil chemistries (mineral,PAO,PAG synthetic)unless confirmed compatible —mixing can cause sludging or reduced lubrication performance.If switching brands,a system flush is the safer option.

This depends on your compressor’s oil capacity and running hours — send us your compressor model and typical duty cycle,and we
can help estimate consumption.

Unopened containers stored properly (sealed, indoors ,stable temperature)retain quality well.Once opened,we recommend using the oil within a reasonable timeframe rather than keeping it as long-term backup stock.
