What is Compressor Oil?

Compressor oil is a special technical fluid used in air and gas compressors. Its main functions are lubricating mechanical parts, cooling heat, reducing friction, and ensuring the long service life of the system.

These oils help maintain compressor efficiency, reduce internal corrosion, and prevent system contamination.

Types of Compressor Oils

Compressor oils play a vital role in ensuring efficient compressor performance, reducing mechanical friction, and optimizing heat dissipation. Choosing the right oil depending on the compressor type, operating conditions, and industry directly affects equipment longevity and performance. Main types include:

• Mineral-Based Compressor Oils
  Obtained through crude oil distillation and manufactured using traditional technology. They are ideal for:

  • Simple and medium-duty systems

  • Equipment operating at low temperatures and pressures

  • Cost-effective applications

  • Environments with no strict cleanliness requirements

• Synthetic Compressor Oils
  Chemically engineered in laboratories and superior in performance compared to mineral oils. Advantages:

  • High resistance to temperature and pressure

  • Better oxidation stability

  • Longer oil change intervals

  • Improved energy efficiency and reduced wear risk

  • Lower reactivity with air, providing stable operation

• Polyalphaolefin (PAO) Based Oils
  Belong to the synthetic oil category and are considered premium-quality products. Benefits:

  • Excellent thermal and oxidative stability

  • Low volatility and evaporation rate

  • Extended oil change intervals

  • High performance even at low temperatures

  • Lower environmental contamination risk

• Esters and PAG-Based Oils
  Designed for special industries and extreme conditions:

  • Corrosive chemical environments

  • Systems working with reactive gases

  • Compressors requiring high purity and stability

  • Water-miscible PAG oils are highly effective in moisture-prone systems

  • Biodegradable options available

Where and Why is Compressor Oil Used?

Compressor oils are applied across various industries for the following types of compressors:

• Screw compressors

• Piston compressors

• Centrifugal compressors

• Scroll compressors

Main purposes:

• Reduce friction

• Cool the system

• Keep internal parts clean

• Minimize corrosion and wear

• Optimize energy consumption

Usage Guidelines and Recommendations

• Select the oil according to compressor type.

• Follow manufacturer instructions for timely oil changes.

• Ensure the system is completely cooled before refilling.

• Avoid mixing with previous oil without compatibility checks.

• Regularly monitor oil level and cleanliness.

Storage Conditions

• Store in a dry, dust-free, and cool environment.

• Protect from direct sunlight.

• Keep sealed and away from moisture.

Compressor oils are crucial for efficient equipment operation, extended service life, and prevention of technical failures. Properly selected and timely replaced oil ensures your compressors run smoothly for many years.
