The purpose of this type ofnozzle is to produce "white or foamy"water jetsin architectural fountains. To do this, it is necessary to create a turbulent flow inside thenozzle, and this is achieved in two ways:
The outlet jet draws acolumn of waterfrom the glass, which must therefore remain submerged (waterfall) (bubbling).
By mixing air and water via the Venturi effect (snow jet). Both features (Geyser, Snow fir) can be combined.
