With a fully adjustable head for optimal airflow in any direction, this versatile unit delivers whole-house air circulation for year-round use, providing summer and winter energy savings by maximizing the performance of a home's current heating and cooling systems. The unit's innovative design moves air 100 feet, while its exclusive vortex action quietly creates swirling, deep-penetrating currents of air that circulate and rejuvenate all the air in a room. In addition, the unit's three adjustable speed controls offer custom circulation, and its unique design allows for out-of-the-way placement from anywhere in the room, even from behind furniture. Other highlights include deep-pitch blades for whisper-quiet operation, a patented removable grill for easy cleaning, and a style that matches virtually any home or office decor. The 84-watt unit measures 15-2/3 by 15-1/5 by 18 inches and carries a limited lifetime warranty.
