Gas jet ventilators convey air, gases and vapors against pressure differences up to approximately 500 m bar. in fact Gas jet ventilators operate on the ejector principle and they convey air against small pressure differences.
We recommend you to read "more details" to know what is a gas jet ventilators completely.

Gas jet ventilator

what is a gas jet ventilator?

Gas jet ventilators operate on the ejector principle and are used to convey air, gases and vapours against small pressure differences. The high velocity gas jet emerging from the motive nozzle draws in and accelerates the suction medium either from the surrounding atmosphere or from the suction housing, depending upon the ventilator construction.

The achievable pressure difference between the suction and discharge pressure is the compression of a gas jet ventilator.
