The Neff D57ML67N0B canopy hood operates by extracting air around the edges of the central black glass panel that covers its filters. It is designed for installation in a kitchen cabinet so that only the intake area with its LED lights and control panel protrudes from the surrounding kitchen unit above your hob. Filters The hood captures grease and smells with two metal grease filter cassettes. An indicator shows when the filters are saturated. Its fan has three speeds, together with a power boost that cuts-in for a six-minute spell when cooking fumes become intense. This hood has touch-sensitive, electronic controls, an LED display and two LED lights to illuminate your cooking area. Usage This canopy hood is suitable for ducted extraction and recirculation. For recirculation, it will require an additional charcoal filter. A recirculation installation kit is available and in recirculation operation, chimless use is possible.
