The hollow spray strip offers a wide range of adjustment options, such as infinitely variable spray adjustment from full jet to protective shower for men and simple flow control from 150 - 660 l/m. The "Flush" function removes dirt particles and foaming agents in the jet pipe if it has been contaminated by dirty water.

The infinitely variable setting of the spray cone allows quick and flexible adjustment and minimizes water damage during fire extinguishing. A large area can be covered with the spray through an opening angle of over 120°, significantly increasing the cooling and extinguishing effect at close range many times over. Extremely small droplets (~ 0.3 mm) increase the total surface area of the droplets and consequently also the cooling effect.
