FAQ
How many CFM does a flex fan pull?
The Flex-A-Lite Flex-Wave electric fans, such as the Flex A Lite 238 model, are known for their high-performance airflow. The CFM (Cubic Feet per Minute) rating of a flex fan varies by model, but the Flex A Lite 238, for example, pulls an impressive amount of air to effectively cool your engine and radiator, ensuring optimal performance in high-demand situations.
What is the difference between a push fan and a puller fan?
A push fan and a puller fan differ in their mounting orientation. A push fan is mounted on the front side of the radiator, pushing air through it. In contrast, a puller fan is mounted on the engine side, pulling air through the radiator. The Flex-A-Lite 16 inch electric fan, like the flx-105390, can be configured as either a push or pull fan, providing versatility to suit your specific cooling needs.
Does a puller fan need a shroud?
While a puller fan doesn't always require a shroud, it is highly recommended for optimal cooling efficiency. A shroud helps direct airflow through the entire radiator, maximizing the cooling effect. When using the Flex A Lite 16 inch electric fan or the Flex-A-Lite Flex-Wave electric fans 238 as a puller, adding a shroud enhances performance and ensures consistent cooling in various driving conditions.
How do you install a Flex a Lite Fan Controller?
Installing a Flex-A-Lite Fan Controller, especially for models like the flx-105390, is a straightforward process. Begin by locating a suitable location for the controller, ensuring it's away from excessive heat. Follow the provided instructions to connect the wiring, temperature probe, and power source. The Flex-A-Lite Fan Controller allows you to customize fan operation based on coolant temperature, providing efficient and adjustable cooling for your high-performance vehicle.
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.
