Compressed air is produced with a low-noise, quiet, oil-free compressor. Of course, as before, the washing frequency can be parameterized and adjusted by the operator according to local conditions.
Our small but informative development in our public restrooms, is that the user receives feedback information on the success of the start of contactless hand washing on the start surface, and a pictogram on the face of the faucet spout indicates that soap and water are dispensed from the same spout. The dispensing of soap, water and the start of the hand dryer, as before, is done with running control, which means that the hand washing process starts with a single hand approach, a short water supply, soap supply, hand washing water supply and finally the hand dryer is started.
