Shell Corena S4 R 46 Air Compressor Oil - 55 Gallon Drum
Sliding vane and screw rotary air compressors operating at discharge temperatures of more than 100 degrees C and pressures in excess of 25 bar require premium oil for maximum protection. Shell Corena S4 R 46 synthetic air compressor oil uses a high-performance additive system that effectively lubricates and protects internal parts. It safeguards against wear and corrosion, and because it minimizes foaming, efficiency is increased.
Long oil life Maintenance saving Shell Corena S4 R is capable of providing oil maintenance intervals of up to 12,000 hours (where allowed by manufacturers) even when operating at maximum discharge temperatures in excess of 100 C. 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. 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 Asian and Pacific regions, a reduced oil drain period is recommended (consult OEM recommendations). Outstanding wear protection Shell Corena S4 R helps provide exceptional protection and protection of internal metal surfaces from corrosion and wear. It contains an advanced ashless anti-wear system to help prolong the life of critical parts such as bearings and gears. Maintaining system efficiency Shell Corena S4 R is designed to provide rapid air release without excessive foaming to give trouble-free operation even under cycling conditions helping to ensure reliable start-up and continuous compressed air availability. Shell Corena S4 R has low volatility and oil carryover to provide reduced oil top-up requirements in combination with increased air quality. In addition, Shell Corena S4 R has excellent water separation properties to help ensure continuous efficient operation of the compressor even in the presence of water.
Main Applications Rotary sliding vane and screw air compressors
Shell Corena S4 R is suitable for oil-flooded/oil injected, single or two-stage compressors, operating at pressures of in excess of 25 bar and with air discharge temperatures of over 100 C (including intermittent operation under these conditions).
Severe service conditions
May also be used where exceptionally high ambient temperatures are found, when the oil temperature cannot be reduced to normal levels.
ABB Turbochargers The product is recommended for use in ABB turbochargers fitted to low and medium speed diesel engines used in marine and power generation applications.
