The revolutionary, patent-pending Flex-Wave electric fan from Flex-A-Lite has greater airflow, is more efficient and is quieter than traditional S-blade and straight-blade designs. The Flex-Wave fan moves up to 20 percent more airflow than Flex-A-Lite Trimline fans, and up to 25 percent more airflow than the comparable electric fans from the competitors! This reversible Flex-Wave fan measure 16-inches in diameter and moves 2, 660 cfm of airflow. More than having just a different look, the Flex-Wave electric-fan blade has several aerodynamic advantages for air movement. Converting from a belt-driven fan to a Flex-A-Lite electric fan frees up wasted horsepower and increases gas mileage. When used as an auxiliary fan, these units will provide additional cooling.
