Two new chrome-plated brass hand-washing faucets that automatically deliver either tempered or hot/cold water are now available from Sloan Valve Co. Electronic pedestal model SF-2100 runs off a 6 VDC plug-in transformer with battery backup, and model SF-2150 is battery powered. The faucets operate by means of an infrared sensor. When the user enters the sensor's effective range, the solenoid activates the water flow. The faucet automatically shuts off when the user steps away. This prevents recontamination from touching a handle to turn off water after washing. Sloan Valve Co.
