The Vornado Duo Compact Tower Circulator offers a more effective way to circulate air with V-Flow Circulation. Uniquely contoured air outlets create a wide span of constant airflow, without the need for oscillation. With V-Flow Circulation, a high volume of air is continuously moving throughout the room, creating quiet, comfortable circulation. Easily adjust the airflow direction in either the tower or low-profile position for even more versatility. The Duo’s innovative one button design allows for simple selection of the circulator’s 4 fan speeds. Backed by Vornado’s 5-year limited warranty.
