Geyser
Fountain Nozzle
The Geyser nozzle is a water and air entraining venturi
type, which augments the effect by adding water volume
from the pool and aerating the mass. This method provides
a heavy punch with moderate aeration to increase visibility.
Compared to the Cascade nozzle, visibility is greater
because the entrained air gives a roiling, white water
appearance. Geysey nozzles are widely used in architectural
fountains due to their high visibility and good wind
resistance. Moderately "hard" in both appearance
and audible impact, the Geyser is best used in large
pools and outdoor applications where a noise masking
water effect is desired. The Geyser nozzle is also a
water level dependent type, and requires a controlled
water level. Several Geyser nozzles can be placed in
close proximity for a striking "picket fence"
effect.

- All Geyser nozzles are water level dependent venturi
types. The surrounding pool water is drawn by venturi
effect through the bottom of the nozzle, while air
is entrained through a slot near the top.
- These nozzles can be submerged in water up to the
slot level. but maximum efficiency is achieved if
the water level is held to the dimensions given. Be
sure to give enough freeboard for the slot such that
wave action won't interfere withthe air intake.
- If placed in fountains of more than one water level,
check valves should be installed inline with the nozzle.
(The discharge orifice of the Geyser nozzle is actually
under water, and if installed in an upper pool of
multi-level fountains, can cause the water of the
upper level to drain back through the display pump
to the lower level.
- This type of nozzle can set up a resonant wave action
in certain pools. If an undesired wave action occurs,
it can be eliminated by adding a copper surge tube
around the nozzle locations. This is a copper tube,
about 6" in diameter, mounted from water level
to about 1" above the pool floor.
- All Geyser nozzles are NPT thread.
