      Perma-Cool Aluminum Flex Fans pull additional air through the radiator at low RPMs when the speed of the vehicle is not enough to cool the engine's coolant system. At higher RPMs, when the vehicle's speed forces ample air through the radiator, the fan blades flatten out, resulting in less power being used to spin the fan. Engine performance and gas mileage are thus improved. Perfect for applications requiring extra cooling such as vehicles with turbo or superchargers, full-sized cars or trucks used for towing.

      All aluminum fans are Standard (RH) Rotation. Narrow blade width and moderate pitch improves air flow with minimal horsepower loss. Available with blue or red anodized blades, and black powder painted or chrome plated finish centers. Exclusive accelerated pitch angle flows substantially more air and the specially designed blade tips minimize fan noise. A two-piece steel center hub provides for positive blade attachment.
