Effective lime protection thanks to the unique elastomer surface (SLC = Smart Lime Cleaning). Lime residues can be easily wiped away with a finger. The automatic cleaning function of the attachment sieve flushes out small dirt particles in the water, ensuring a longer lifespan. Hygiene is improved as less lime means less bacterial growth. The mixing nozzle does not need to be disassembled for cleaning. It also provides protection against vandalism, as the sieves can no longer be pressed in. Features a gentle comfort spray. Not suitable for unpressurized water heaters.
