The Atlas Copco RS Ultra Compressor Oil, also known as Roto Synthetic Fluid Ultra, is a high-performance synthetic-based lubricant designed specifically for oil-injected rotary screw compressors. Developed by Atlas Copco, this oil combines a premium synthetic base fluid with an advanced additive package to deliver outstanding lubrication and protection under severe operating conditions.

This compressor oil offers extended drain intervals of up to 4000 hours or 2 years, significantly reducing maintenance frequency and operating costs. Its excellent resistance to oxidation and deposit formation keeps internal compressor components clean, while maintaining consistent performance over time.

The RS Ultra oil features a high viscosity index, ensuring stable lubrication even under varying temperatures and heavy loads. It also provides superior protection against wear, corrosion, and rust, enhancing the lifespan of critical components such as rotors, bearings, and gears. Additionally, its low volatility and efficient air/oil separation properties help reduce oil consumption and improve overall compressor efficiency.

Compatible with a wide range of Atlas Copco compressor series such as GA, GX, GN, and GR, this oil is ideal for use in industries requiring continuous and reliable compressed air supply. Designed for harsh environments including dusty and humid conditions, RS Ultra ensures optimal performance, reduced downtime, and long-term equipment reliability.
