The time consuming ways of installing hoods are now a thing of the past. The FIT system eliminates measuring, cutting and filler strips for a perfect fit every time. Once installed, homeowners enjoy the quiet operation of 5.3 sones at its highest speed with two fan speeds and recirculation option. This way, the KitchenAid UXT4036ADB-BL vent hood doesn't disturb family time in the kitchen. And when cooking introduces steam, grease, smoke and odors into the surrounding air, a 190 CFM fan takes care of it.
