Description:

Shell Corena S4 R is an advanced synthetic air compressor oil incorporating a unique high performance additive system. It is designed to deliver the highest performance lubrication of rotary sliding vane and screw air compressors. It uses an advanced additive system to provide excellent protection and performance for compressors running at pressures over 25 bar and in excess of 100⁰C discharge temperatures with oil maintenance intervals of up to 12,000 hours.

Performance, Features & Benefits:

•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 1000C. 
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. 

Application:

•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 1000C (including intermittent operation under these conditions).
