Steam jet ventilators are delivered in cast iron EN-GJL-200 (GG20), steel, stainless steel, plastic material. Moreover, special materials of construction are possible, such as Titanium, Hastelloy
Steam jet ventilators, also called ejectors, convey air, gases and vapours against small pressure differences up to approximately 500 mbar and are used, eg:
- to draw of waste air, exhaust gases and vapour
- to ventilate tanks
- as forced blast blowers, or stack ventilators for boiler burners
- to extract and mix exhaust gases from the thermal afterburning
The achievable pressure difference between the suction pressure and discharge pressure is the compression of the steam jet ventilator.
