Innovation, well-being, efficiency and sustainability come together in GREEN VERTIGO by Simas, the new silent water drainage system that allows with a reduced amount of water, only 4 and/or 2.5 liters, to ensure complete cleaning even on the inside of the toilet, in compliance with UNIEN997 regulations, avoiding the formation of limescale and bacterial deposits. Highly appreciated especially in the hotel industry, where it ensures acoustic comfort and low water consumption.
