- Oxidation resistance: Oil-soluble polyether as synthetic base oil significantly improves oxidation stability and prolongs service life;
- High cleanliness: Oil-soluble polyether is a polar base oil (mineral oil, PAO, etc. are non-polar), which can effectively dissolve polar polymers, with excellent cleaning performance, effectively inhibit the generation of sludge;
- Wear resistance: Lubrication additives and oil-soluble polyether complement each other and promote the role of effective reduction of component wear;
- Thermal conductivity: Oil-soluble polyether has high specific heat capacity and heat transfer coefficient, which enhances the cooling effect of the system.
Ultra SL 4000 is an engineered synthetic lubricant formulated to provide optimum reliability for rotary screw air compressors. Ultra SL 4000’s unique formulation extends your compressor life and increases total system efficiency versus non-Ingersoll Rand lubricants. With a recommended 4,000 hours of service between change-out under normal operating conditions, it helps align your lubricant to your operating needs.
