Vent hoods are traditionally designed to hide cooking odors but in doing so they can add bulky, unsightly structure to your streamlined kitchen. The Viking downdraft ventilation system not only gets rid of undesirable smells and smoke, it retracts into your countertop leaving nothing but a sleek cooking surface behind. Suitable for both island and wall installations of Viking Designer cooktops, such ventilation systems raise and lower into your countertop at the touch of a remote control button. These compact downdraft ventilation systems feature dishwasher safe baffle filters and minimal interior space, making cleanup an easy task. Featuring four variable fan speeds for your desired level of ventilation, the Viking ventilation system has a delay/off feature that allows for operation for 10 minutes before automatically shutting off. Stylishly designed with stainless steel finish, this rear downdraft ventilation system is available in 30″, 36″ and 45″ models. Viking. Previously, downdraft Jenn-Air cooktops.
