The Neff D57MH56N0B canopy hood operates by extracting air around the edges of the central panel that covers its filters - all adding to the sleek good looks of this stainless steel unit. Filters The hood captures grease and smells with two metal grease filter cassettes. Its fan has three speeds, together with a power boost that cuts-in for a six-minute spell when cooking fumes become intense. It 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.
