Whirlpool 30-in Telescoping Stainless Steel Ducted Downdraft Range Hood - FOR COOKTOPS

Retractable downdraft systems remain flush with the cooktop surface until needed. A reversible motor box can be installed on either side of the downdraft, freeing up space beneath the cabinet. The 14-inch rise allows for greater smoke and steam capture.

•     Stainless steel downdraft range hood features a retracting design that sits flush with the cooktop to save space in your kitchen
•     Dual centrifugal blower moves more air, and operates more quietly than an axial-type bladed fan (600-CFM blower motor included for island installations)
•     Variable speed knob controls allow for precise ventilation and optimum performance
•     Touch-activated telescoping operation keeps fresh air flowing during the peak cooking periods in your kitchen
•     Top-button turns the blower off and automatically returns the retractable section of the vent to closed position
•     Aluminum grease filters help improve operating efficiency
•     Installs as a 6-in round for ducted vent
