Hello,

Could anyone please educate me the differences between Eductor and Ejector? When do we use Eductor or Ejector? Any related web site will be appreciated too.

Many thanks,

Hahi:

Eductors and ejectors both have the same funtionality in that they both use a motive fluid to produce some vacuum. In fact, some dictionaries say that the two words are synonymous.

In general, when the motive fluid is a gas and the produced vacuum is used to evacuate or to vent a vessel or system, I would use the word ejector.

When the motive fluid is a liquid and the produced vacuum is use to draw in another fluid or a powder and mix it with the motive fluid, then I would use the word eductor.
