Corena S4 P 68 - Advanced Synthetic Rotary Air Compressor Oil 209L Drum

Shell Corena S4 P 68 is an advanced synthetic air compressor oil for reciprocating piston compressors. Formulated with synthetic ester base fluids and high performance additives, it provides reliable protection at very high discharge temperatures and can extend valve maintenance intervals to about 2000 to 4000 hours depending on operating conditions.

Key Uses

• High-pressure reciprocating compressors. Designed for elevated pressures and discharge temperatures up to about 220 °C.

• Demanding environments. Provides consistent protection in hot, humid or dusty conditions.

• Breathing air compressors. Suitable when used with appropriate downstream clean-up equipment to ensure air quality.

Benefits and Features

• Extended oil life. Helps extend typical valve maintenance periods to about 2000 to 4000 hours, reducing downtime and maintenance costs.

• Superior wear protection. Protects bearings, gears and internal components to support longer service life.

• Thermal and oxidation stability. Resists sludge and deposit formation at high operating temperatures to maintain efficiency.

• Deposit control. Helps limit carbon and lacquer on valves and pistons for cleaner operation.

• Water and air separation. Good demulsibility and low foaming properties support reliable compressor performance.

• Efficient operation. Supports smooth startup and stable performance under varying load and temperature conditions.

Shell Corena S4 P 68 is engineered to provide long-lasting protection, efficient operation and extended service life for reciprocating compressors in demanding industrial environments.
