12in Pusher Fan Straight Blade 861 CFM

The 12in Pusher Fan Straight Blade 861 CFM by SPAL Advanced Technologies is a low-profile electric cooling fan engineered for automotive enthusiasts and engine builders who demand efficient thermal management in tight engine compartments. This pusher-style fan mounts on the radiator's engine side, pulling cool air through the core and directing it toward the engine block—an ideal configuration for custom vehicle builds, swap applications, and track-focused setups where space is limited or traditional puller fans create airflow conflicts with headers or intake manifolds.

This unit delivers 861 CFM of pushthrough airflow at 12V DC operation, providing robust cooling capacity while maintaining a compact 3.75-inch overall thickness that fits retrofit applications where factory fan shrouds cannot accommodate larger assemblies. The straight-blade design minimizes turbulence and maximizes laminar airflow efficiency compared to curved alternatives, while the plastic construction reduces weight and inertia—critical for vehicles where underhood real estate and engine bay temperature control directly impact performance. At 6.44 pounds and measuring 13 inches in diameter with straight blades, this SPAL fan integrates seamlessly into custom radiator shrouds, fabricated mounting brackets, and aftermarket cooling system setups without adding significant mass or complexity.

Street rod builders, LS swap specialists, and water-cooled engine conversions benefit most from this pusher fan's low-profile design and proven SPAL reliability, which eliminates the need for expensive custom shrouding modifications typical of generic alternatives. Installation pairs well with adjustable thermostat housings, electric fan controllers, and multi-stage cooling strategies on high-output engines where consistent coolant temperatures prevent vapor lock and overcooling. The 861 CFM rating provides sufficient air movement for street and mild track use, while the 12V system integrates directly with standard automotive wiring, relays, and engine management harnesses, making this fan an essential upgrade for any serious mechanical enthusiast pursuing dependable, efficient engine cooling.
