The 615L Vornado Air Circulator can move air up to 70 feet! Unlike a household fan, the Vornado air circulator uses signature vortex technology to fully circulate all the air in the room, creating even cooling throughout. Ideal for small to mid-size rooms, such as a bedroom, kitchen or office. Operates at a whisper-quiet level. The tall stand allows for convenient placement behind furniture. The 615L has a three-speed control, fully directable airflow and a 5-year limited warranty. Unlike an ordinary house fan, a Vornado air circulator doesn't just blow air. Instead, it literally bends and twists air to produce true whole-room air circulation using Vortex Action, exclusive to Vornado. So rather than drafts and dead spots you get an even temperature and circulation through out the room. Vornado air circulators save energy year-round by working with heating and cooling systems. In the Summer months, place near a window or air conditioning vent to circulate the cool air. This enables you to raise your thermostat up to 5 degrees and maintain the same comfort level. In the Winter take advantage of heat already in the room, direct the airflow upwards to circulate warm air that gravitates to the ceiling back to floor level.
