The KitchenAid KXU2830YSS 30" recirculating range hood features 4-speed electronic control includes an LED display that offers feedback on fan speed setting and a 5-minute boost function provides extra ventilation when needed. Ventilation system may be placed over a cooking surface with a maximum heat output up to 65K BTUs. Four speeds and a 400 CFM motor help you keep your kitchen fresh, no matter what you're cooking. When extended for use, the ventilation system automatically starts up on the last used speed. The tempered glass canopy with aluminum trim offers a sleek look and only extends when the vent is in use. Premium dishwasher-safe mesh filters help keep the kitchen fresh, drawing steam, grease, and odors through the hood.
