Look up and you’ll appreciate its linear design, but otherwise Onyx-C blends into the background, and all you notice is the pure air. Onyx-C incorporates FABER’s exclusive SIL & STILL technology. This new technology includes an Eco button that activates an ultra-silent mode to bring your kitchen maximum comfort with minimum energy consumption. The button’s green light is the sole proof the system is working. The silence is broken only by applause for the Faber technology that places the hood in energy efficiency class A++.
