Shell Corena S46

Shell Corena S46 is a premium quality lubricant developed for the lubrication of rotary sliding vane and screw air compressor units. It is based on a blend of selected solvent refined base oils and carefully chosen additives.

Applications

• Rotary sliding vane air compressors
• Oil flooded or oil injected, single or two-stage compressors, operating at pressures of up to 10 bar and with air discharge temperatures of up to 100°C.
• Screw air compressors
• Oil flooded or oil injected, single or two-stage compressors, operating at pressures of up to 20 bar and with air discharge temperatures of up to 100°C.

Advice on applications not covered in this specification may be obtained from Gannon Oils Ltd.

Performance Features and Advantages

• Very good oil oxidation resistance. Resists formation of carbon deposits in sliding vane slots, enabling them to move freely. Also resists deposit formation on rotating components of screw compressors. As a consequence, high levels of compressor efficiency can be maintained for long periods in both types of compressor.
• Very good air release and anti-foam properties. The careful selection of base oils and additives provides rapid air release without excessive foaming to give trouble-free operation even under cycling conditions.
• Very good rusting and wear protection. Effectively protects all metal surfaces from corrosion. Protects all sensitive machinery parts, e.g. gears, screws, bearings, from wear and prolongs the service intervals.
• Internal cleanliness. Coupled with the oil's long life capability is its ability to maintain internal surface cleanliness in service. This is important to maintain high levels of performance for the compressor and separator/coalescer.
• Oil drain periods. Corena S will allow the oil drain period to be extended to 4000 hours, even when operating at a continuous maximum discharge air temperature of up to 100°C.
