For a cost-effective and reliable sensor-operated faucet built with durability and commercial environments in mind, here's Zurn's AquaSense Z6915 Series. Seamless and sleek, this 4-inch deck-mount sensor faucet will maintain its polished chrome-plated finish despite high usage. The battery-powered Z6915-XL-N's infrared proximity sensor senses the user for precise hands-free operation. For a long-term power solution, hardwired, plug-in, or our EcoVantage Hydroelectric Generator options are available. Its water-conserving 0.5 gpm laminar flow outlet and 30-second timeout feature are a safer option for healthcare applications or a money-saving choice anywhere laminar flow is preferred. AquaSense sensor faucets are constructed of high-quality lead-free cast brass making them a durable, water-efficient choice for new commercial and retrofit construction projects alike.
