The HD Flex Fan 18in Reverse Rotation from PERMA-COOL is designed for engine builders and mechanics who require efficient cooling solutions without the drawbacks of traditional mechanical fans. This fan is particularly useful in tight engine bays where standard fans may not fit due to custom configurations.
This 18-inch flex fan features a reverse-rotation design that adjusts blade pitch according to engine RPM, optimizing cooling performance while minimizing energy consumption. The flexible polycarbonate blades are engineered to flatten under centrifugal force, reducing drag and horsepower loss, making it suitable for both naturally aspirated and forced-induction engines.
Ideal for applications in Chevy small-blocks, Ford 302s, and other setups requiring custom mounting, this fan provides substantial air displacement while maintaining a lightweight profile. Its design allows for effective cooling across standard aluminum or copper radiators, making it a versatile choice for performance enthusiasts.
