Marvell Atlas 55 Rotary Screw Compressor Oil (20L)

High Performance Air Compressor Lubricant – Mineral Based NDURANCE Equivalent

Product Overview

Marvell Atlas 55 is a premium mineral-based rotary screw compressor lubricant engineered to deliver reliable performance, extended service life and superior protection in oil-injected air compressors. Designed as an equivalent performance solution to leading compressor oils such as Atlas Copco NDURANCE fluids, this lubricant is formulated with advanced additive technology to ensure excellent oxidation resistance, stable viscosity and long-term system cleanliness.

Rotary screw compressors operate under continuous load, elevated temperatures and exposure to contaminants such as dust, humidity and airborne particles. These conditions place extreme demands on the compressor lubricant, requiring consistent film strength, high thermal stability and resistance to deposit formation. Marvell Atlas 55 is specifically developed to meet these requirements by providing optimal lubrication for rotors, bearings, gears and seals across a wide range of operating environments.

With a carefully tuned viscosity of approximately 55 cSt at 40°C, Marvell Atlas 55 ensures efficient sealing between rotor elements, improved compression efficiency and reduced energy losses. The formulation supports reliable operation in both clean and contaminated environments while maintaining oil stability and protecting internal components from wear, oxidation and corrosion.

The product is suitable for use in a wide range of oil-injected rotary screw compressors, particularly those operating in industrial, mining, manufacturing and workshop applications. It is ideal for businesses seeking a high-quality compressor oil with extended service intervals and consistent performance under demanding Australian conditions.

Key Features & Benefits

Extended Service Life – Up to 4000 Hours

Marvell Atlas 55 is designed for extended drain intervals, reducing maintenance frequency and operational downtime. Under normal operating conditions, service life can reach up to 4000 hours, improving productivity and lowering maintenance costs.

High Oxidation Resistance

The advanced additive system protects the oil from oxidation under high temperature conditions. This prevents sludge, varnish and deposit formation, ensuring the compressor remains clean and efficient over long operating cycles.

Optimised Viscosity for Efficient Compression

With a viscosity of approximately 55 mm²/s at 40°C, the oil provides excellent sealing between screw rotors, improving compression efficiency and reducing internal leakage.

Superior Anti-Wear Protection

The lubricant forms a durable protective film on metal surfaces, reducing wear on bearings, rotors and gears, extending equipment life and improving reliability.

Excellent Water Separation

Moisture contamination is common in compressor systems. Marvell Atlas 55 separates water quickly, maintaining lubrication performance and preventing corrosion inside the system.

Low Foaming and High Air Release

Foaming can cause pressure instability and reduced efficiency. This oil’s low foam tendency and fast air release ensure consistent compressor operation and improved performance.

Cleaner System Operation

The formulation prevents lacquer and sludge formation, keeping oil circuits, separators and valves clean. This reduces maintenance and avoids pressure drops caused by contamination.

Reduced Oil Carryover

Low volatility base oils reduce oil consumption and minimise carryover into compressed air systems, improving air quality and reducing downstream contamination.

Reliable Performance in Harsh Conditions

Designed to perform in dusty, humid and high-temperature environments, making it suitable for mining, construction and heavy industrial use.
