A retractable downdraft range vent is a stovetop filtration system that is raised during cooking times and then retracted until it is level with the cooking surface when not in use. It is intended for kitchens equipped with cooktops consisting of just the burners or heating elements from a range.
A retractable downdraft range vent is an especially appealing option for kitchens with no room for an overhead hood ventilation system or other confining design features. Unlike a conventional range, which is a freestanding appliance that must be backed against a wall, a cooktop stove can be installed just about anywhere there is counter space and hook-ups to your cooking fuel, even in the kitchen island if desired, but such a set-up requires special ventilation.
Thermador introduced the first retractable downdraft ventilation system in 1978. The downdraft filter is crafted for both function and design and is compatible with gas, electric or induction cooktop stoves. The unit lowers to provide clear sight lines for the kitchen, so it does not clash with any interior design elements. When cooking, the unit is raised from the counter top to remove fumes, odors, moisture and other airborne contaminants. The simple concept also makes the retractable unit easy to remove and keep clean.
