Rather than being suspended over the range, downdraft hoods form sort of a backsplash behind the range which sucks up the smoke and blows it downward, venting out behind the oven itself.
Rainbow Appliance offers a selection of name brand, downdraft cook top hoods for pulling out smoke and steam caused by range and stove cooking. Ideal for small kitchens, downdraft cooktop hoods attach to the back of your range. Downdraft cooktop hoods are available with many options including fan control and lighting. When space is limited, downdraft hoods are a great kitchen exhaust solution.
