SYNTHVACUUM EST SERIES is a premium range of synthetic ester-based lubricants specially developed for lubrication of mechanical vacuum pumps operating under demanding conditions. The series is formulated using selected synthetic ester base fluids combined with a carefully balanced additive system to provide excellent thermal and oxidation stability, low volatility, good lubricity, cleanliness and resistance to deposit formation. The lubricant is particularly suitable where conventional mineral vacuum pump oils may suffer from rapid oxidation, viscosity increase, carbon formation or shortened service life.
