Gas jet ventilators convey air, gases and vapours against pressure differences up to approximately 500 mbar.
Gas jet ventilators are used:
to draw off stale air, ill-smelling gases and vapours from working and storage areas
to ventilate tanks, e. g on ships
as forced blast blowers or stack ventilators for boiler burners
for the circulation of air, in particular in the textile, leather and tobacco industries.
to deaerate reaction vessels, agitator vessels and other items of equipment in chemical factories
The achievable pressure difference between the suction and discharge pressure is the compression of a gas jet ventilator.
