The hollow jet nozzle offers a variety of adjustment options, including a stepless spray pattern adjustment from full jet to a man protection spray, and a simple flow control ranging from 150 to 500 l/m. The "Flush" function removes dirt particles and foam agents from the hollow jet nozzle in case of contamination due to dirty water.

The stepless adjustment of the spray cone allows for quick and flexible adaptation, minimizing water damage when extinguishing a fire. The spray jet can cover a large area with an opening angle of over 120°, significantly increasing the cooling and extinguishing effect in the immediate vicinity. The extremely small droplets of about 0.3 mm increase the overall surface area of the droplets, thereby enhancing the cooling effect as well.
