Vornado's first V-Flow tower fans introduced a wide, continuous range of air to create whole room circulation. Now, we've added oscillation - bringing the best of both worlds to Vornado consumers. V-flow airflow plus oscillation truly puts a new twist on your airflow experience. 70 of rotational range are expanded to an impressive 130 of powerful, cooling airflow with V-Flow air diffusion. OSC73 offers the same V-Flow whole room circulation that you've come to expect from Vornado, and for those who like options, there is also powerful oscillation on-demand. Oscillation channels legendary Vornado power and sound quality into the panoramic airflow experience Vornado enthusiasts have been asking for.
