Mobil Vaprotec Light

Rust-Inhibiting Circulation Oil

Mobil Vaprotec Light is an ISO Viscosity Grade 32, turbine-quality circulation oil containing anti-oxidants and defoamants. It is enhanced with a three-phase rust inhibitor to protect surfaces lightly coated with oil; a liquid phase inhibitor to protect surfaces submerged in oil; and vapor space inhibitors to protect surfaces exposed to oil vapors.

Features and Benefits

  • Wide-temperature-range rust protection for steel surfaces in the vapor (air) spaces which do not come into contact with the oil
  • Rust protection for metal surfaces where the oil has drained off, leaving only a thin film
  • Rust protection for surfaces which are submerged in the oil
  • Good corrosion protection for nonferrous metals
  • Demulsibility equivalent to that of a normal turbine oil
  • Superior oxidation stability
  • Wide range of application


Mobil Vaprotec Light is recommended for all applications requiring an ISO Viscosity Grade 32, turbine-quality oil with additional rust protection properties. Operation of systems with oil temperatures above 120°F will deplete the vapor phase inhibitors.
