Mushroom Fountain Nozzle Bell, umbrella or so called Mushroom nozzle creates a clear water bell pattern in the adjustable shape. It makes the least noise and splash fountain effect compared to other jets. The relaxing sound of splashing water is particularly effective in silent wind-free locations like the water garden, indoor reception hall, or outdoor pool that are protected from the wind. Bell nozzles are water level independent and can be located in dry areas. The Mushroom Jet produces a sheet of transparent water thanks to a fully laminar flow of water at the outlet. The name comes from the bell-shaped sheet of water it produces. Crystalline and laminar jet performed by the Mushroom Jet has little wind resistance, although this also depends on the thickness of the water film. Due to its operating speed, noise level is very low, which makes it particularly suitable for indoor fountains. As it does not depend on the level of water in the fountain pond, it is advisable to set to a height at which the film does not break when it falls.
