The 12-1/8-inch Flex-A-Lite Lo-Profile Dual S-Blade Electric Fan System offers an ultra-thin design to optimize engine cooling where engine clearance is an issue. Built in the USA with globally sourced materials, this pusher-puller / reversible radiator cooling fan has an airflow of 2500 CFM. It features a durable shroud and two S-blade fans with eight blades each that direct airflow through the radiator core and produce less noise than other engine-cooling car accessories and truck accessories. With overall dimensions of 15-1/2 x 26-1/4 x 2-5/8 inches, this car fan draws 22 amps from a 12-volt power supply. Mount this radiator fan system as a puller behind the radiator as a stock belt-driven fan replacement to increase engine power and efficiency.
