Liquid Jet Ventilators

Liquid jet ventilators operate on the jet pump principle and are designed for large gas flows at a small compression ratio. The liquid jet emerging from the motive nozzle expands and disperses into evenly distributed single droplets hitting and entraining the surrounding air or gas, conveying and compressing it to a higher pressure. A chemical reaction is also possible.
