Oil Analysis for Rotary Compressors: Protect Your Investment

Oil Analysis: Protecting Your Rotary Compressor from the Inside Out

Oil is the lifeblood of your rotary stationary air compressor. But simply changing it on schedule isn’t always enough. Regular oil analysis offers a deeper look at your machine’s health, helping you prevent failures before they start.

Why Perform Oil Analysis?

Oil analysis provides critical data on both lubricant condition and internal wear. By detecting problems early, you can avoid costly repairs, extend component life, and keep your compressor operating efficiently and reliably.

What Oil Analysis Reveals

  • Viscosity Changes: Indicates oil breakdown or possible contamination.
  • Wear Metals: Helps identify internal wear in components like bearings and rotors.
  • Contaminants: Detects dirt, water, or coolant leaks affecting lubricant quality.
  • Additive Depletion: Shows if protective additives are exhausted and oil performance is compromised.

Using an Oil Analysis Kit

Our Oil Analysis Kit makes it easy to gather and submit samples for testing. Each kit includes everything you need to capture a clean, accurate oil sample — no complicated equipment or lab setup required.

How to Take a Proper Oil Sample

Correct sampling technique is crucial for reliable results. We’ve put together a detailed guide covering each step, from warming up the compressor to sealing and labeling your sample. For a full walkthrough, check out our blog on Six Steps to Take an Oil Sample.

Interpreting Results and Acting Quickly

Once you receive your analysis report, work closely with your maintenance team to interpret the findings. If you see high levels of wear metals or contamination, address the root causes immediately. Don’t wait for a costly breakdown to force your hand.

Long-Term Advantages

Routine oil analysis supports better maintenance planning, reduces unplanned downtime, and maximizes ROI on your compressor investment. Over time, it also builds a comprehensive health history that can guide major decisions like rebuilds or replacements.
