Screw air compressors are in the important position in the industrial process, therefore all aggregates break and troubleshooting affect to industrial process in general and have not expected results. Screw air compressors quality and advantages are undeniable, but every mechanism is run-out eventually, some parts do not operate stably, some are out of operation.

2. Long life span - saving maintenance cost.

Shell Corena S3 R has mantenance cycle up to 6000 hours ( permitted by manufactures) even when it is operated at 100ºC ( maximum discharg temperature).

Benefits :
-Avoid the formation of condensed carbon in vane air compressors.
-Avoid the formation of condenser in rotary parts in screw air compressor.
-Avoid the decomposition caused bt temperature and condenser to maintain the clealines of surface especially in oil/ air filter system.
Maintenance cycle is depended on the amount of intake air, operating cycle and environmental condition.To very hot and humid climates in Asia Pacific, it is recommended to reduce the oil change cycle (refer to the original manufacturer's proposal).
Excellent anti-wear properties
Applied sucessfully for many years, Shell Corena S3 R is well-protected metal surface from the corrosion and abrasion.This oil contains a high-quality non-ash anti-wear additive system to help extend life in key parts such as bearings and gears.
Maintenanace the effect of system
Dischargeing air and anti-foarming are key features in compressor oil, ensuring good and continous operation air compression. Shell Corena S3 R is designed to discharge air quickily without creating excessive foam to operate continously, even in cycle. In addition, Shell Corena S3 R has water separation feature to ensure efficient and continuous air compressor operation even when water is available.
