Manufacturer's description
Shell Corena S4 P is a synthetic air compressor oil formulated on a blend of ester-based synthetic fluids and a unique, high-performance additive system. It is designed to deliver maximum performance in the lubrication of high-pressure reciprocating compressors with air discharge temperatures above 220 °C and continuous delivery of high-pressure air.
Applications
- Reciprocating air compressorsShell Corena S4 P can be used to lubricate all industrial reciprocating air compressors, particularly those operating under severe air discharge conditions, with air discharge temperatures above 220 0 C and continuous delivery at high pressure.
- Breathing-air compressorsShell Corena S4 P can also be used to lubricate air compressors used with breathing apparatus, provided the equipment used is clean, to ensure that the air produced is suitable for breathing.
Performance & benefits
- Long service life – reduced maintenanceShell Corena S4 P has been formulated to provide operational reliability and to ensure safe, proper lubrication over extended operating periods, where the use of a mineral oil would be unsatisfactory. Shell Corena S4 P helps ensure high compressor performance over extended operating periods and reduces maintenance costs and downtime. Shell Corena S4 P can extend the normal valve maintenance period from 1,000 operating hours with conventional mineral oils to 2,000 or 4,000 hours, depending on operating conditions.
- Excellent wear protectionShell Corena S4 P helps ensure exceptional protection of internal metal surfaces against corrosion and wear, helping to extend the life of critical components such as bearings and gears.
- Maintaining system efficiencyShell Corena S4 P helps prevent the formation of carbon deposits and protects against varnish on valves and piston crowns at high operating temperatures and pressures. Shell Corena S4 P has good water separation capability to prevent accelerated corrosion, facilitating condensate draining.
- Improved air line safetyThe combination of rust particles, carbon deposits and high operating temperatures in air discharge lines can cause an exothermic reaction that can lead to compressor ignition and explosion.
- Miscibility: Shell Corena S4 P oils are fully miscible with mineral oils, although dilution with mineral lubricants would significantly reduce performance
Standards & approvals
DIN 51506 VDL
Air compressor oil -VDL — DIN 51506
