Zurn's Aqua-FIT Serio Series® Single Post Sensor Faucet combines high functionality and customization with simple installation. Its chrome-plated heavy-duty cast brass body holds up in high-use commercial environments. Our Aqua-FIT® Sensor Faucets now come standard with Hydro-X Power to deliver seamless, sustainable performance at the sink—up to ten or more years without a single battery replacement! The technology generates enough power from only a few activations a day, even with the lowest flow rate, to optimize both energy and water. The Z6950-XL-S-M is a single hole, deck-installation with a concealed, downward-facing sensor to help prevent tampering and increase durability. Its convergence-type infrared proximity sensor is accurate and efficient, while the faucet's water-conserving 0.35 gpm non-aerated spray outlet and 30-second timeout feature maximize water conservation and cost savings. The Aqua-FIT® Serio Series® offers a quick and easy solution for upgrading any commercial retrofit project.
