16in Pusher Fan Straight Blade 1604 CFM

The SPAL 16in Pusher Fan Straight Blade 1604 CFM is a medium-profile electric cooling fan engineered for serious automotive builders and engine enthusiasts who demand reliable thermal management without the complexity of mechanical clutch systems. As a pusher-type unit, this fan mounts behind the radiator core, drawing ambient air through the cooling matrix and expelling it rearward toward the engine bay—a configuration preferred in tight engine compartments and custom builds where space is at a premium. Whether you're tuning a street machine, building a track car, or upgrading an older vehicle with modern cooling capacity, this SPAL unit delivers consistent airflow when you need it most.

Built with a straight-blade design, the 16-inch fan achieves 1604 CFM of airflow at 12V DC operation, providing substantial cooling capacity for mid-sized engines and modest displacement builds without requiring a dedicated alternator upgrade on most vehicles. The plastic blade construction reduces weight and inertia, minimizing parasitic drag compared to cast-metal designs—a critical advantage when every horsepower counts. At 2.5 inches thick and weighing just 4.95 pounds, the compact profile fits within tight radiator shrouds and doesn't interfere with serpentine belts or headers. The 12V electrical design integrates easily with OEM or aftermarket wiring harnesses, and standard mounting allows installation into universal or vehicle-specific shrouds without custom fabrication.

This cooling fan is ideal for hot-rod builders, street-rod restorers, and performance enthusiasts upgrading from mechanical fans or undersized electric units that cannot keep up with modern traffic and summer temperatures. The pusher configuration works best in applications where radiator clearance and engine-bay packaging allow rear-mounted installation, making it a go-to choice for custom water-cooling loops and vintage restorations that demand space efficiency. Pair this fan with a quality thermostat switch (180°F or 195°F pull-in) to automate engagement and avoid unnecessary cooling load; many builders also wire the unit through a relay for reduced electrical strain on the factory alternator. Verify your radiator shroud dimensions against the 17.5 x 18.1-inch fan diameter to ensure a secure fit, and confirm 12V supply availability before ordering.
