Ejectors
are steam jet vacuum pumps which use the energy of a steam jet to entrain, mix
and compress low pressure gas (100 to 300 Torr) up to atmospherich pressure.
When more vacuum is required, two, three or four stages with interstage
condensers are required:
 |
One
stage:
up to 100 Torr
|
|
Two
stages:
up to 25 Torr
|
|
Three
stages: up to 6 Torr
|
|
Four
stages: up to 0.75 Torr
|
|
Five
stages: up to 0.25 Torr
