Liquid jet ventilators are used to draw off air, gases or vapour
Liquid Jet Ventilators from GEA Wiegand, also called inductors, employ a liquid, very often a scrubbing liquor, as the motive medium to entrain air or another gas. There is a small pressure gain across the unit, but the main duty of the liquid jet ventilator is to convey/entrain large volumes of gas. They are employed to draw air from ventilation hoods or work areas, or as pre-ejectors for packed scrubbers, performing part of that scrubbing duty and also meaning that a mechanical fan may not be required.
