Synthetic oil ST 755 1L

COLTRI OIL ST 755 is a fully synthetic oil, specially developed for the long-term lubrication of gas compressors in industrial processes and, in particular, for breathable air. It offers outstanding performance for all types of compressors. Coltri Oil ST 755 is based on a long and historical experience of over 70 years in the industrial, commercial and military sectors, offering the user considerable economic benefits combined with significant technical advantages. The formula of Coltri Oil ST 755 lubricant is an optimized blend of synthetic hydrocarbons and pure synthetic esters, with selected and specific additives. It is produced exclusively in state-of-the-art industrial units in Italy.

• Extended drain intervals up to 8 times – Coltri Oil ST 755 synthetic oil has a much longer service life than mineral oils due to the exceptional thermal and oxidative stability of its components.
• 30–50% reduction in oil consumption – At 100°C it has an extremely low volatility compared to a mineral oil of the same viscosity. Combined with a lower operating temperature due to superior lubrication, this leads to a significant reduction in consumption and requires less oil stock.
• Extended component life – Compared to mineral oils, Coltri Oil ST 755 reduces friction and wear in compressors due to its lower coefficient of friction and optimal anti-wear additives, resulting in less wear, longer maintenance intervals and reduced costs.
• Keeps compressors clean – Leaves no residue and cleans carbon deposits produced by mineral oils. The superior oxidation resistance and thermal stability of Coltri synthetic components reduce carbon deposit formation, which means less maintenance, less downtime and increased safety.
• Excellent adhesion to metal surfaces – Thanks to the polarity of the special molecules, it minimizes wear during cold starts and in difficult working conditions.
• The ideal choice for high temperatures – Coltri Oil ST 755 has a wide temperature range (-15°C to +250°C), making it usable in all seasons. Its high temperature resistance allows for efficient use without seasonal oil changes, reducing the risk of contamination with the wrong oils.
• Increased fire safety – Coltri synthetic oil significantly reduces the risk of accidental fires. With a flash point of approximately 60°C and an autoignition temperature of approximately 120°C higher than mineral oils, with low volatility and reduced carbon deposits, the safety margin is considerably increased.

Coltri Oil ST 755 guarantees maximum performance, safety and protection for breathing air compressors, extending their lifespan and reducing maintenance costs.
