Hollow jet belongs to the family of smart nozzles; it shoots a crystal clear stream of water, looking perfectly solid to the eye, yet being hollow inside. This jet creates water columns twice as thick as a solid-stream nozzle using the same water capacity, making it the most efficient clear-water nozzle.

Hollow jets make an excellent choice for great spray heights – above 15 meters as the water capacity required is significantly less compared to the visual results. The inside – made of stainless steel – flow directors create a highly visible and stable water stream.
