Previous Name: SHELL CORENA AS

Shell Corena S4 R series air compressor lubricants are high performance fully synthetic lubricants with a unique high performance additive system. They are designed to deliver the highest performance lubrication of rotary sliding vane & screw air compressors. They provide excellent protection for compressors running at pressures over 25 bar and in excess of 1000C discharge temperatures with oil maintenance intervals of up to 12000 hours. They are also suitable to cover applications where a synthetic bearing and circulating oil or R&O oil (ISO VG 32 -68) is needed. Shell Corena S4 R series lubricating oils are available in 46 & 68 ISO Viscosity Grades.

Performance Benefits

• Long oil life – Maintenance saving.
• Outstanding wear protection.
• Enhanced airline safety.
