Increased Fan Efficiency Using Less Energy 

Flex-A-Lite has pushed electric fan technology further by using advanced engineering to develop the Flex-Wave. Flex-A-Lite's patent-pending Flex-Wave fan blade features improved efficiency and greater airflow through a sine-wave design. Sine-wave blades feature serrated knife-like leading edges that cut through the air first, causing improved efficiency in air startup movement. The winglet and wave surface design further increases efficiency by creating air channels and reducing air vortices, resulting in distinct airflow improvements while using less energy. Flex-Wave fans also use unique variations in fan blades trailing edge for a reduction in wind noise, resulting in a fan that's not only quieter but can flow more air than other similar size fan packages.
