7.5in Puller Fan Straight Blade 437 CFM

The SPAL Advanced Technologies 7.5-inch Puller Fan Straight Blade (437 CFM) is a high-performance electric cooling fan engineered for serious automotive builders and mechanics seeking efficient thermal management in modified engines. Whether you're running a street rod, custom truck, or high-output engine bay, this puller-style fan pulls air through your radiator core to enhance cooling capacity without sacrificing underhood real estate. SPAL's reputation in the aftermarket cooling sector makes this unit a trusted choice for enthusiasts who demand reliable temperature control in demanding driving conditions.

Designed with a straight-blade configuration, the 7.5-inch fan delivers 437 CFM of airflow efficiency—a specification that reflects optimal balance between cooling capacity and electrical draw. The puller design mounts on the radiator's engine-side surface, pulling ambient air backward through the core rather than pushing, which reduces turbulence and maximizes heat rejection from modified radiators. At just 2.45 lbs, this lightweight construction minimizes rotational inertia and parasitic engine load, critical considerations for builders prioritizing efficiency and horsepower retention in high-revving or fuel-injected builds.

Mechanics and hot rodders favor SPAL puller fans for applications ranging from vintage engine swaps to modern turbocharged conversions where factory cooling is inadequate. The compact 10.6 x 2.5 x 10.9-inch footprint allows flexible mounting in tight engine compartments, and the straight-blade design minimizes shroud interference common with curved-blade alternatives. Installation pairs well with quality aluminum radiators, electric thermostatic controllers, and modern engine management systems, ensuring your cooling system responds dynamically to real-time engine demands rather than relying on mechanical fan clutches.
