- Premium quality reciprocating air compressor lubricant
Shell Corena S4 P is a top-tier reciprocating air compressor lubricant. It is based on synthetic ester fluids and incorporates the latest additive technology to pro-vide the highest possible performance.
- Applications
All industrial reciprocating air compressors (Specially recommended for reciprocating compressors operating at continuous high pressure (30 bar and over) and high tem-perature (discharge at 180°C).
Shell Corena S4 P may be used in machines compressing air for breathing purposes (such as air bottles for divers).
- Performance Features
+ Superior lubrication performance
In all operating conditions, including the most demanding operations where mineral oils are unsatisfactory
+ Long maintenance intervals
The absence of deposit formation enables the normal valve cleaning process, typically between 250 and 1,000 hours of operation, using conventional mineral oils, to be extended to 2,000, or even 4,000 hours.
+ Outstanding performance in all operating conditions
Including reciprocating compressors sub-jected to overloading, intermittent or continuous operation, poor installation, high compressor room temperatures
+ Increased safety
Absence of deposit formation has a very important safety-related benefit. It is com-mon for pipework in an old installation to be virtually choked with carbon. This carbon deposit material is inflammable, and fires and explosions can occur under certain circumstances.
These conditions lead to rapid oil degradation and causes varnish and coke to be formed on components such as valves, inter-coolers and pipework. Such deposits on valves cause leakage, which quickly reduces compressor efficiency. On air outlet pipework, deposits can build up and may cause fires and explosions if allowed to remain.
- Breathing Air
Shell Corena S4 P may be used in machines compressing air for breathing purposes (such as air bottles for divers) provided strict conditions are adhered to.
- Performance Specifications
DIN 51506 - VD-L level
ISO/DP 6521 - ISO-L-DAB - medium duty
ISO 6743 - ISO-L-DAC -heavy-duty
- Seal Compatibility
Shell Corena S4 P, in common with other ester-based lubricants, is not compatible with all seal materials, and some older compressors may need to have the seals changed before they can be run on the new grades.
- Health & Safety
Shell Corena S4 P is unlikely to present anysignificant health or safety hazard when properly used in the recommended application, and good standards of industrial and personal hygiene are maintained.
