Mobil Oil and Greases Distributor - East Coast Lubes - Compressor Oils - Air

Diester synthetic lubricants for severe duty, multistage compressors that provide outstanding deposit control and long lubricant life. These products also provide excellent air separation and possess low foaming tendencies. These superior lubricants are recommended for use in high-severity rotary and most reciprocating air compressors. They are especially effective in multi-stage units where there has been a history of excessive oil deposits, whether in large or small cylinders at high or low pressure. Mobil Rarus 800 Series are designed to lubricate both cylinders and crankcases and minimise carbon and sludge deposits in critical high temperature areas.

• Excellent oxidation and high temperature stability
• Increased service intervals between cleaning of valve, parts and inter-coolers
• Excellent air separation and minimum foaming tendency
• Minimised deposit formation
• High autogenous ignition temperatures and flash points
• Reduced fire risk
• Not compatible with mineral oils

Fully synthetic rotary screw air compressor lubricants designed for continuous high temperature duty. Their superior thermal and oxidation stability enables them to be particularly effective in screw type compressors with oil injection cooling and in compressors with high final compression temperatures or having tendencies towards coke formation and deposits. They are excellent in compressors where extended drain intervals, long service life and excellent protection against wear are required.

• Reduced maintenance and reduce lubricant consumption
• Reduced fire and explosion risk
• Prevents deposits and coking. No corrosion
• Low volatility with high performance over a wide temperature range
• Good air separation
• Compatible with materials normally used in compressors

Specifically designed for single and multistage reciprocating and rotary air compressors, they can be used for both crankcase and cylinder lubrication. Mobil Rarus 400 Series are made from specially refined mineral base oils and selected additives to give excellent thermal and oxidation stability to resist deposit formation on exhaust valves.

• Rust protection with good load carrying ability and demulsibility
• Longer valve cleaning intervals as a result of high resistance to deposit formation
• Good inter-cooler and after-cooler efficiency due to resistance to emulsion formation
• Lower operating costs as a result of long crankcase charges, due to high oil stability

Mobil Rarus 427 is a premium performance ashless air compressor lubricant designed to meet the stringent requirements of major compressor manufacturers. It is formulated with high quality mineral base-oils and a high performance additive system designed to provide exceptional equipment protection and reliability for modern compressors operating under mild to severe conditions in marine and industrial applications. It provides excellent wear protection and the ability to reduce maintenance costs by minimising downstream deposits and carryover. Because of its high FZG Ratings, Mobil Rarus 427 is an outstanding lubricant for compressor systems employing gears and bearings making it an excellent selection for crankcases as well as cylinder lubricants.

Mobil Rarus 427 exceeds the requirements of DIN 51506 VD-L standards and demonstrates a very high resistance to oxidation and deposit formation. It is recommended or approved by many of the leading compressor manufacturers.

Specifically designed for single and multistage reciprocating and rotary air compressors, they can be used for both crankcase and cylinder lubrication. Mobil Rarus 400 Series are made from specially refined mineral base oils and selected additives to give excellent thermal and oxidation stability to resist deposit formation on exhaust valves.
