The TMC-20 Vacuum Pump Fluid from TMC Industries, supplied by Econtrol Devices, is a high-performance vacuum pump fluid designed as an alternative to Invoil 20 Oil. TMC-20 is a hydrotreated paraffinic oil that is two-pass distilled through a molecular distillation process to remove light end fractions. The fluid is highly saturated and contains less than 0.01% sulfur, providing exceptional long service life and vacuum performance while reducing the build-up of varnish and carbon deposits on internal components.
Developed for professional vacuum applications, TMC-20 Vacuum Pump Fluid delivers reliable lubrication and stable vacuum system performance. Its formulation offers higher viscosity index for superior lubrication, greater resistance to thermal decomposition, higher molecular weight for reduced backstreaming, reduced aromatic content, and extremely low sulfur content. These characteristics help maintain consistent operation in demanding industrial vacuum systems.
Applications
TMC-20 Vacuum Pump Fluid is recommended for use in:
Vacuum Pumps
Diffusion Pumps
Leybold Blowers
Note: TMC-20 is not recommended for oxygen and highly reactive gas loads.
