The Mizutani Auto Valve System is a non-contact automatic handwashing apparatus, ideal for both entrances and living spaces, and it is the first in the world able to generate ultra-fine bubbles through sensor-operated taps, delivering mist and bubbles at the same time and in a rhythmic pattern. The high-sensitivity sensor allows touch-free, hygienic washing, and the mist-bubble combination saves water and reduces splashing, as does the integrated tap and bowl design.
