IMPROVED EFFICIENCY
SEVERE APPLICATIONS
Advanced Synthetic Reciprocating (Piston) Air Compressor Oil
Shell Corena S4 P is an advanced synthetic air compressor oil incorporating synthetic ester
base fluids and a unique high performance additive system. It is designed to deliver the
highest performance lubrication for high pressure reciprocating compressors running in excess
of 220oC discharge temperatures at elevated pressures.
