This extractor is discreetly flush mounted, allowing the cabinetry and outdoors to take center stage.However, when it's time to cook, Siena will easily do the job: with a powerful 600 CFM and in-line blower (sold separately), which can mounted in the attic for added silence and peacefulness. The 43-inch x 27-inches size provides excellent capture of fumes and the Perimeter Aspiration Technology has been included increasing suction 35 percent, making it a highly effective hood despite its out-of-sight location. Both the bright LED lighting and the 4 speed blower are conveniently operated by an ergonomic remote control.
