Flex-A-Lite Flex-Wave Electric Fans

Flex-A-Lite Flex-Wave electric fans are the revolutionary way to move more air! These patent-pending electric fans not only produce greater airflow, but are also more efficient, and quieter than traditional S-blade and straight-blade designs. Designed using advance software and tested in a wind tunnel to verify increased airflow and improved efficiency, Flex-Wave fans move up to 20 percent more airflow than Flex-A-Lite Trimline fans, and up to 25 percent more airflow than the comparable electric fans on the market. With a new look, a selection of sizes available, and several aerodynamic advantages, Flex-A-Lite Flex-Wave electric fans are ready to cool your high-horsepower applications. Advantages include: * The leading edge of the fan blade is no longer a single, solid line. The sine-wave design creates leading edges that cut through the air first. This starts movement in the air around the blade with greater efficiency. * The wave surface of the blades creates channels for the air to move along, producing more airflow and reducing energy losses. * The wave surface forms a winglet at the tip of the blade, further increasing efficiency by reducing air vortices. * The trailing edge of the fan blade also has variations, which reduces wind noise.
