Turbo Molecular Pumps (Compound Molecular Pumps) Exhaust Theory
Turbo molecular pumps consist of moving and stator blades arranged on multiple levels.
The figure below shows the relation between the angle and rotating direction of the blades.
Gas molecules inbound from the high vacuum side enter the moving blades and try to exit in various directions. However,
the angle and rotation of the blades cause the molecules to move toward the exhaust end and through the quickest path in the stator.
Gas molecules that flow back from the rearmost stage through the stator hit the moving blade, sending them back to the exhaust end.

Typical Benefits of the Turbo Molecular Pump
- Provides an oil-free ultra-high vacuum.
- It features roughly the same exhaust rate for all gases in order to mechanically exhaust parentheses (dynamically exhaust) gas molecules.
- It can also exhaust noble and corrosive gases.
- It can continually exhaust large flow volumes of gas.
- Wide working pressure range (to 10-10Pa).
Osaka Vacuum's Turbo Molecular Pumps Lineup
Uses grease lubricated ball bearings for a pump that is small, lightweight, and low cost.
