How a Venturi Injector works

 Click HERE to see a video on how the venturi injector works

 A venturi injector pulls ozone/oxygen gas into the water stream under a vacuum and dissolves that ozone/oxygen gas into water very efficiently.  A pressure differential across the orifice in the venturi creates a high-velocity jet stream of water.  This high velocity of water results in a decrease in absolute pressure and creates a vacuum on the third leg, or gas suction let.  This gas is quickly and efficiently dissolved into the water directly after this venturi.

 

Ozone/Oxygen gas is pulled into the water.  The gas fills the void created by the suction action of the venturi to entrain the gas bubbles into water very efficiently.
