Inspecting and Changing Vacuum Pump Fluid
The fluid in the vacuum pump should be changed every three months or when the efficiency of the
vacuum pump declines (requiring increased time to reach vacuum levels). The fluid can first be
inspected to determine if a change is necessary.
Use oil supplied by Micromeritics, or refer to the vacuum pump manual for other acceptable oils.
Inspecting Fluid
1. View the vacuum pump fluid through the oil level window. Fluid in good condition is clean, clear
or light in color, and transparent. If the color of the fluid is darkened, the fluid should be changed.
This procedure applies to oil-sealed vacuum pumps only.
