Adjustable and delayed self-switching off:This function allows you to programme a delayed range hood shutdown which provides the right level of air purity in your kitchen. Light indicator for grease filter maintenance:The range hood automatically informs you when the grease filter designed for trapping grease in the air requires cleaning. It is of utmost importance to clean these filters to ensure range hood components are protected and to prevent bad odours caused by a build-up of grease Perimeter extraction:This consists of a mechanical system that literally forces pushes the cooking fumes extracted along a slit that runs along the perimeter of the range hood. This system increases extraction performance whilst reducing range hood noise emission. Design and appearance are also improved as the grease filters are no longer visible.
