The objective of this type of nozzle is to generate "white or foamy" jets of water in ornamental fountains.
For this, it is necessary to generate a turbulent regime within the nozzle and this is accomplished when the outlet jet drags a column of water and mix the air and water by venturi effect. Both effects are combined (Geyser, cascade).
This is one of the most widely used nozzles in ornamental fountains, due to its simplicity of installation and its attractive snowy foam effect. It is a nozzle that does not depend on the water level in the installation..
