Gas Jet Ventilators convey air, gases and vapours against small pressure differences up to approximately 300 mbar. Their basic operating principle is the same as that of a Jet Pump. The high velocity gas jet emerging from the motive nozzle draws in and accelerates the suction air, gas, or vapour. The kinetic energy of the gas, air or steam mixture is then re-converted to pressure energy in the diffuser.
Gas Jet Ventilators are used:
- to draw off stale air, noxious gases and vapours from working and storage areas
- to de-aerate reaction vessels, agitated vessels and other plant in chemical installations
- to ventilate tanks, for example on ship-board
- as forced blast blowers, or stack ventilators for boiler combustion chambers.
Gas Jet Ventilators are available in the following standard materials:
Carbon steel, rubber-lined steel, cast iron, stainless steel, plastics (pvc, polypropylene, etc.);
or in special construction in titanium, hastelloy, or many others.
Gas Jet Ventilators are available in three different constructions:
- Without Head giving free access to the entrained media
- With Axial Suction Connection
- With Lateral Suction Connection
