Choosing the Right Oil for Your Rotary Screw Compressor

When it comes to maintaining your rotary screw compressor, choosing the right oil is crucial for optimal performance and longevity. With so many options available on the market, how do you know which oil is the best fit for your compressor? Let’s dive into the key factors to consider when selecting the perfect oil for your rotary screw compressor.

Understanding Viscosity Grades

One of the most important factors to consider when choosing compressor oil is viscosity. Viscosity determines the oil’s resistance to flow and plays a significant role in lubrication. Different compressor models require specific viscosity grades to operate efficiently. It is essential to consult your compressor’s manual to determine the recommended viscosity grade for your machine.

Synthetic vs. Mineral Oil

Another crucial decision to make is whether to use synthetic or mineral oil in your rotary screw compressor. Synthetic oils offer superior performance in extreme temperatures and provide better lubrication, resulting in reduced wear and tear. Mineral oils are more cost-effective but may not offer the same level of protection and longevity as synthetic oils. Consider your compressor’s operating conditions and maintenance schedule when deciding between synthetic and mineral oil.

The Importance of Using Atlas Copco Genuine Compressor Oil

In a rotary screw compressor, oil does far more than lubricate. It prevents metal-to-metal contact, manages heat, seals clearances to stop air leaks, and traps contaminants for removal. For these critical functions, the right oil makes all the difference.

Atlas Copco genuine compressor oils are formulated specifically for Atlas Copco machines, using a unique blend of additives developed through extensive testing and industry expertise. This ensures optimal lubrication, reduced wear, cleaner operation, and consistent performance even in demanding conditions.

Generic oils may seem like a budget option, but they’re not designed to meet the exact needs of Atlas Copco compressors. Using them can cause deposits, corrosion, oil carryover, poor air quality, and premature equipment failure — and can even void your warranty.

Choose Atlas Copco lubricants to maximize efficiency, extend service life, and keep your compressor running reliably for years to come.

Why Choose Atlas Copco Genuine Compressor Oil?

Engineered for Atlas Copco equipment – tested and approved for optimal performance

Superior protection – reduces wear, oxidation, and deposit buildup

Improved efficiency – maintains sealing and cooling for peak output

Cleaner operation – minimizes oil carryover and protects air quality

Longer service life – extends both oil change intervals and equipment lifespan

Warranty compliance – protects your coverage and avoids costly repairs

Additive Considerations

Compressor oils often contain additives to enhance performance and protect internal components. Common additives include anti-wear agents, rust inhibitors, and detergents. When selecting compressor oil, ensure the additives align with your compressor’s requirements. The right formulation can significantly extend the life of your equipment.

Oil Change Intervals

Regular oil changes are essential to maintain your compressor’s efficiency and prevent costly repairs. The frequency of changes depends on factors such as operating conditions, temperature, and workload. Always follow your compressor’s manual for recommended intervals.

Consulting with Experts

When in doubt, seek advice from compressor experts or your manufacturer. They can provide valuable guidance based on your compressor’s specifications and operating environment, helping you make an informed decision.

By considering factors such as viscosity, oil type, additives, and — most importantly — choosing Atlas Copco genuine compressor oil, you can protect your investment, maintain efficiency, and ensure reliable operation for years to come.
