Shell Corena S4 P Series
Advanced Synthetic Reciprocating (Piston) Air Compressor Lubricating Oils
Previous Name: Shell Corena AP
Shell Corena S4 P series air compressor lubricants are high performance synthetic lubricants with a unique high performance additive system. They are designed to deliver the highest performance lubrication for high pressure reciprocating compressors operating under severe conditions of air discharge temperatures in excess of 220 oC at elevated pressures. Shell Corena S4 P series lubricating oil is available in ISO Viscosity Grade 100.
- Long oil life – Maintenance saving.
- Outstanding wear protection.
- Enhanced airline safety.
- Enhanced system efficiency.
- Synthetic ester based lubricating oil.
- Reciprocating air compressors
Shell Corena S4 P is suitable for use in industrial reciprocating air compressors, in particular those operating under severe conditions of air discharge temperatures in excess of 220 oC with continuous high delivery pressures.
- Breathing air compressors
Shell Corena S4 P may be used in breathing air compressors, provided subsidiary clean-up apparatus is used to ensure that the air produced is fit for breathing.
Specifications and Approvals
- DIN 51506 VDL ISO /DP 6521-L-DAB-medium duty.
- ISO 6743-3:2003DAB – severe duty
- EN 12021
Shell Corena S4 P lubricants are fully miscible with mineral oils, although dilution with mineral lubricants will markedly reduce its performance.
Since Shell Corena S4 P lubricants are synthetic ester based lubricants, they are not compatible with all seal materials. Some older compressors may need to have the seals changed before they can be run on the new grades.
