turbomolecular (not comparable)
(of a pump) That uses a high-speed turbine to drive molecules (of a gas) in a specific direction
A cryopump or turbomolecular pump would be used to bring the pressure further down to 10 −8 Torr (1 µPa). Source: Internet
As a result, it is possible to use much smaller backing pumps than would be required by pure turbomolecular pumps and/or design more compact turbomolecular pumps. Source: Internet
Operating principles Most turbomolecular pumps employ multiple stages, each consisting of a quickly rotating rotor blade and stationary stator blade pair. Source: Internet
Diffusion pumps blow out gas molecules with jets of oil or mercury, while turbomolecular pumps use high speed fans to push the gas. Source: Internet
In most cases, the exhaust is connected to a mechanical backing pump (usually called roughing pump ) that produces a pressure low enough for the turbomolecular pump to work efficiently. Source: Internet
Multiple turbomolecular pumps in a lab or manufacturing-plant can be connected by tubes to a small backing pump. Source: Internet
