This 36" island-mount hood can be installed over ranges or cooktops with outputs up to 65K BTU. Auto speed sensing adjusts the fan speed to protect cabinets from steam, grease and moisture, while perimeter ventilation increases efficiency by pulling air from the edges and speeding up the air in the center. LED task lights and halogen night lights give you ideal lighting at all times, and the Whisper Quiet System ensures quiet operation at 49 dBA at low speed. 600 CFM/65K BTU Threshold Allows installation over any KitchenAid regular 36- or 30-inch range or cooktop, and some commercial-style cooking surfaces with outputs up to 65K BTU. Perimeter Ventilation Increases ventilation system efficiency by pulling air from the edges of the hood and speeding up the movement of air at the center, allowing it to efficiently handle up to a 65K BTU total output. Auto Speed Setting Takes the guesswork out of protecting cabinets from steam, grease, and moisture by automatically adjusting fan speed to ventilation needs depending on the heat being produced. Automatic Turn On Helps protect your cabinets from damage by automatically turning the vent on when it senses the presence of heat. LED Task Lights Provide extra lighting over the cooking surface to help in the cooking process. Halogen Night Lights Enhances the style of the ventilation system by providing soft, accent lighting in the kitchen. Whisper Quiet® System @ 49 dBA (1.5 sones) at Low Speed Ensures that the ventilation system operates at a quiet level so it can be used while entertaining. At maximum speed, sound level is 65 dBA (5.4 sones). Dishwasher Safe Grease Filters Filter reduces steam, grease, and odor to help avoid contact with ceilings and countertops. The design increases filtration by obstructing the path of vented air to help capture more steam, grease, and odors as they are drawn through the vent. Easy In-line Conversion Converts from a traditional set-up to an in-line blower installation for an even more quiet operation. Metal box purchase required.
