TOPFAST Tenia S4V
170kg
Features and Benefits
• Excellent thermal and oxidation stability ,reduces sludge formation ,improves performance of hydraulic pumps and control valves,and extends oil and filter change intervals.
• High Viscosity Index ensures effective protection for system components under both cold start and high operating temperatures.
• Outstanding shear stability minimizes viscosity loss after long-term use and delivers stable viscosity performance under high-shear conditions.
• Excellent demulsibility enables rapid water separation and prevents emulsion formation.
• Unique rust and corrosion inhibitors protect multi-metal components from corrosion damage in the presence of water.
• Good air release properties minimize cavitation risk in hydraulic pumps,especially in modern small-tank hydraulic systems, reducing vibration and maintaining efficiency.
• Provides long-lasting hydrolytic stability and good compatibility with yellow metals even in wet conditions.
• Compatible with a wide range of metallic materials and most seal materials commonly used in hydraulic systems.
Application Scope
• Suitable for hydraulic and power transmission systems operating in environmentally sensitive areas under various climates and operating temperatures.
• Applications requiring extended oil drain intervals.
• Critical hydraulic systems,such as high-precision CNC machine tools and hydraulic systems using close-tolerance servo valves.
• Hydraulic systems for excavators,cranes and hydraulic drives operating under severe outdoor conditions.
• High-pressure hydraulic systems demanding high-level load-carrying capacity and anti-wear protection.
