Sloan's Optima Plus EBF-85 touchless, sensor-operated faucet blends ADA compliance and state-of-the-art engineering. The EBF-85 features microprocessor-based circuitry that automatically adjusts the faucet's sensing range to the type, depth and reflectiveness of the sink on which it is installed, ensuring functionality in any atmosphere. By emitting a continuous beam of infrared light, the faucet's sensor activates the water flow cycle when a user's hands enter the active area. When the user is finished, the loss of reflected light ends the cycle, conserving water that might otherwise flow unattended. The EBF-85 also has a valve mechanism with a self-cleaning bypass that activates with every cycle, and each faucet has a clean-out strainer that traps debris before it enters the solenoid.
