Effective limescale protection thanks to the unique elastomer surface (SLC = Smart Lime Cleaning). Limescale residues can simply be rubbed away with the finger. Automatic cleaning function of the attachment sieve (auto-clean function): Small dirt particles in the water are rinsed out. This results in a longer service life. Hygiene: less lime means fewer bacteria breeding grounds. Mixing nozzle does not have to be dismantled for cleaning. Protection against vandalism: no more pressing in of the sieves possible. Soft comfort jet. Not suitable for pressureless water heaters.
