Our new line of Energy Smart ™ air circulators includes the 783DC. The 783DC combines classic Vornado styling with a brushless DC motor to ensure more-powerful airflow (up to 100') while using up to 80% less energy. For complete versatility, the 783DC can also be assembled in two different height configurations: 25” or 37.5” tall. A return to variable speed puts you in precise control of your environment, and our signature Vortex Action creates whole-room circulation, keeping the entire room cool and comfortable.
