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.
