Description:

Shell Corena P is a premium quality reciprocating air compressor lubricant. It is based on a blend of specially selected base oils to provide a level of performance approaching that of synthetic oils. 

Applications:

• Reciprocating air compressors Industrial reciprocating air compressors operating with air discharge temperatures of up to 220°C.

• Breathing air compressors Corena AP may be used in breathing air compressors, provided subsidiary clean-up apparatus is used to ensure that the air produced is fit for breathing. Corena P 150 is approved for use in Bauer breathing air compressors.

Advice on applications not covered in this leaflet may be obtained from your Shell representative. 

Performance Features and Benefits:

• Prolonged service intervals Allows the interval between valve and piston maintenance to be extended. Compressors can be kept in service for much longer periods, operating at a consistently high level of efficiency.

• Safe air lines In discharge air-lines, the combination of rust particles, dispersed in carbonaceous deposits, coupled with heat from recently compressed air, can cause an exothermic reaction leading to the possibility of fires and explosion. Corena P helps to minimise the likelihood of this danger arising.

• Very good oxidation resistance Resistant to the formation of carbon deposits and lacquer on valves and piston crowns, caused by the by-products of corrosion, such as ferric oxides and hydroxides, at high working temperatures and pressures. Such deposits can cause serious damage, lower compressor efficiency and increase maintenance costs.

• Very good rusting and wear protection Effectively protects all metal surfaces from corrosion. Protects all sensitive machinery parts, e.g. housings, valves, bearings, from wear and prolongs the service intervals. 

• Very good air release and anti-foam properties The careful choice of additives ensures rapid air release without excessive foaming.

• Very good water separation properties Corena P separates readily from water allowing excess water to be drained from the oil circulation system, thus preventing accelerated corrosion and a reduction in lubrication efficiency. This also helps to separate oil from condensate in oil/water separators and drier units.
