The TOTO Libella Semi-vessel Ecopower or AC 0.35 GPM touchless bathroom faucet Spout, 20 second on-demand flow is ideal for high-traffic spaces, providing an elegant water conservation solution. The sensor is strategically positioned underneath the spout head to accurately sense the hands for touchless use. The 0.35 GPM 20 second on-demand faucet uses only 0.12 gallons per cycle and is CEC and CALGreen compliant. The on-demand system means that water flows only when needed and cannot be accidentally left running. When hands are present, the water will flow, and when hands are removed, the water will stop. The Eco Cap aerating technology balances the amount of air bubbles in the water for a comfortable experience while saving water. The spout works with your selection of compatible TOTO Ecopower or AC controller systems. Included items: spout only.

These faucets only operate when the sensor detects the presence of hands and quickly shut off when not needed. Further, TOTO has innovated the use of water as a power source by designing sensor flush valves and faucets, under the trade name EcoPower, that use the kinetic energy of flowing water to power their electronics, greatly reducing maintenance and eliminating battery disposal, which helps to protect the environment.
