How carbon deposits form
In reciprocating and rotary screw air compressors, oil is exposed to high temperature and contact with compressed air. If the oil lacks sufficient oxidation stability, it gradually breaks down and forms carbon deposits on valves and discharge lines.
Why this is dangerous
Carbon deposits don't just reduce compressor efficiency — in compressed-air systems with concentrated oxygen, they can also raise the risk of sudden ignition. This carries particularly high safety importance in power plants, where auxiliary compressors must run without interruption.
The fix: low-deposit oil and periodic inspection
Oils like MAADANOL COMP-R are formulated with high oxidation stability specifically to reduce deposit formation. Alongside choosing the right oil, periodic inspection of discharge valves and monitoring compressor operating temperature are two complementary steps for controlling this risk.
Key Takeaways
- Low oil oxidation stability is the primary cause of carbon deposits
- Carbon deposits threaten both efficiency and compressor safety
- Pair periodic valve inspection with a high-quality, low-deposit oil
