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 4.5 sones at highest speed with two fan speeds and recirculation option. This way, the vent hood doesn't disturb family time in the kitchen. And when cooking introduces steam, grease, smoke and odours into the surrounding air, 190 CFM takes care of it.
