Inland 19 Vacuum Pump Oil

Inland 19 is Inland Vacuum’s recommended general purpose hydrocarbon fluid for mechanical vacuum pumps used in non-corrosive applications. The manufacturing process of Inland 19 includes molecular distillation, which removes light end fractions present in the fluid and gives it the desired properties: lower vapor pressures, reduced backstreaming, and longer fluid life. As a result, it can be used within the same applications as more expensive diffusion pump oils which would otherwise be contaminated by a vacuum oil of lower grade.

A durable, long-lasting mechanical pump fluid, Inland 19 is cost-effective in vacuum applications such as mass spectrometers, electron microscopes, thin film sputtering, UHV systems, and freeze dry systems. Proper use of this oil effects reduced maintenance costs, improved pumping cycles, and a cleaner vacuum system.
