The lively bubbling water pattern generated by the foam effect nozzles is the optimal accessory for watercourse inlets, stepped pool installations, or fountain installations with a water reservoir at a lower level. By mixing air with water, the pattern appears to be extremely high-volume. Nevertheless the nozzles actually have a low water requirement. The beautiful soft foam jet offers a strong contrast to its environment. As opposed to Cascade and Geyser nozzles, Schaumsprudler nozzles work independently of the water level so that fluctuations in the water level do not affect the water pattern.
