Product Description

The Whirlpool W11129407 Range Downdraft Vent Transition Kit is a product that is created to make the venting of kitchen equipment as smooth and efficient as possible. This kit attaches the range to a downdraft ventilation system that pulls smoke, steam, and odors down through a vent instead of up through the kitchen. It fits seamlessly between the range and downdraft vent and provides a more direct and effective airflow path, maintaining a cleaner kitchen because it doesn’t accumulate grease or cooking smells.
