The Elite downdraft is installed directly behind the cooktop – when it’s not in use it’s flush to the surface of the cooktop. If you didn’t know what you were looking for, you’d probably never notice it. The rest of the downdraft vent system is installed under the counter. Its slim profile saves precious space in the cabinet below your cooktop. The hood rises 9/12″ above the cooktop when activated – ideal for large pots and pans. The vent hood automatically raises into position with the touch of a button. And then it disappears into the counter, flush with your cooktop. Its infinitely adjustable control is designed to provide convenient access so you can control the blower speed for effective and quiet operation. The internal blower is rated at 500 cfm (cubic feet per minute of air moved). External blowers are also available in eight different configurations. The Broan Elite downdraft comes in 30″, 36″ and 48″ widths and is finished in stainless steel for that professional look. The units can not be installed behind ranges or ovens.
