Shell Corena S4 R 68

Advanced Synthetic Rotary Air Compressor Oil     Performance, Features & Benefits Long oil life – Maintenance saving Shell Corena S4 R is capable of providing oil maintenance intervals of 10,000 hours (where allowed by manufacturers) even when operating at maximum discharge temperatures in excess of 1000C. This may be extended up to 12,000 hours under certain conditions. The advanced formulation of Shell Corena S4 R helps deliver exceptional oil life through:    Exceptional resistance to thermal and chemical breakdown. Resist formation of deposits on rotating components in screw compressors and in sliding vane slots for        continuous efficient operation. Exceptionally low levels of deposit formation to help maintain excellent internal surface cleanliness particularly in oil/air separator and coalescer systems. The exact oil maintenance interval will depend on intake air quality, duty cycle and ambient conditions. For hot and humid type climates as found in the As
