Product Description
VacOil® 20 Grade is a severely hydro-treated paraffinic oil that is double distilled through a molecular distillation process to remove light end fractions. Unique in comparison to competitive oils, VacOil® 20 Grade is highly saturated and contains less than 0.01% sulfur similar to technical white oils. Its high molecular weight and viscosity index provides longer service life and reduced build up of varnish and carbonized oil on the internal pump components. VacOil® Grade 20 vacuum pump oil is ideal for rotary vane pumps and high vacuum blowers, and eliminates cross contamination when used in mechanical and diffusion pumps.
