Zurn's AquaSense Z6915-XL-TMV-1 is a cost-effective and reliable, sensor-operated faucet built with durability and commercial environments in mind. Seamless and sleek, this 4-in. deck-mount sensor faucet will maintain its polished chrome-plated finish despite high usage. The battery-powered 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 0.5 gpm aerator and 30-second timeout feature save water and help keep costs down. Other flow control options include non-aerated and laminar flow with flow rates as low as 0.35 gpm. Features a single-faucet thermostatic mixing valve for advanced temperature control. AquaSense sensor faucets are constructed of high-quality cast brass; great for new commercial and retrofit construction projects alike.
