Flex-a-lite 234 Flex-Wave Reversible Electric Fan, 14"

• 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.
• Made in the USA

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 14-inch Flex-Wave fan moves 1,900 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.
