Shell Corena S4 P 68

Application:

Shell Corena S4 P 68 is an advanced synthetic air compressor oil formulated using ester base oils and a high-performance additive package. It is specifically designed for industrial reciprocating (piston-type) air compressors operating under severe thermal and pressure conditions, including discharge temperatures exceeding 220 °C. It is also suitable for breathing air compressors when used with proper downstream filtration equipment to ensure air quality.

Performance Features & Benefits:

• Extra Long Oil Life: Extends typical valve maintenance intervals from 1000 hours (with mineral oil) to 2000–4000 hours depending on operating conditions.
• Superior Wear Protection: Protects internal compressor parts such as bearings and gears from corrosion and mechanical wear.
• Maintains System Efficiency: Prevents harmful carbon and lacquer buildup on valves and piston crowns even under high-temperature operation.
• Improved Air Line Safety: Minimizes risk of fires or explosions in discharge lines by reducing carbonaceous deposit formation.
• Effective Water Separation: Facilitates clean drainage of condensate and resists moisture-related system issues.

Main Application Areas:

• Industrial reciprocating air compressors with discharge temperatures >220 °C
• High-pressure piston compressors in severe-duty environments
• Breathing air compressors (with proper air-cleanup systems)

Specifications & Approvals:

• DIN 51506 VDL
• ISO 6743-3 L-DAB – Severe duty
• EN 12021 (breathing air with proper cleanup equipment)

Environmental & Safety Information:

• Use proper skin protection and avoid prolonged contact. Wash thoroughly with soap and water after handling.
• Do not discharge into drains, soil, or watercourses. Dispose through authorized oil collection facilities.
• Safety Data Sheet (SDS) available via inquiry
