Product Description The Vornado 143 Whole Room Tower Air 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. Typical tower fans oscillate due to limited range of air movement. You feel the airflow for only seconds at a time. With V-Flow Circulation, a high volume of air is continuously moving throughout the room, creating quiet, comfortable Whole Room Circulation. The 143 features a remote control that magnetically cradles at the top of the unit, so the remote is always in reach. 3 Speed settings, selected by push-button controls, allow you to tailor the airflow perfectly for your needs. The 143 Tower Circulator includes a 1, 2, 4, or 8 hour timer ensures you run you operate in an energy-saving, efficient way. Vornado has eliminated the wobbly base found on oscillating tower fans in favor of a solid and sturdy system that stands the test of time. Like all Vornado Whole Room Circulators, the 143 is backed by an industry-leading 5 year warranty. Model is made for 120 volts only.
