18in Stainless Fan

The DERALE 18 inch Stainless Fan (model 19118) is a mechanical flex-blade cooling solution designed for serious engine builders and street mechanics who demand reliable heat rejection without electronic complications. This 18-inch pusher-style fan addresses a critical problem in high-performance and heavy-duty cooling systems: maintaining consistent engine temperatures under sustained load, whether you're running a carbureted big-block, a vintage muscle car, or a heavily modified street engine.

Built for durability and simplicity, this stainless steel fan represents the kind of no-nonsense cooling hardware that separates purpose-built machines from everyday drivers. Constructed from corrosion-resistant stainless steel, the 18-inch blade assembly delivers superior airflow consistency by operating mechanically in sync with engine RPM, eliminating the lag associated with thermostat-triggered electric fans. The flex-blade design reduces noise and vibration while maximizing air movement across the radiator core—a critical advantage when you're pushing cooling capacity to its limits in tight engine bays or high-ambient conditions.

Weighing just 2.95 pounds, this fan integrates into standard radiator shroud assemblies on mid-size and large-displacement platforms without excessive weight penalty. The stainless construction resists road salt, coolant, and other harsh elements, ensuring long-lasting performance. This fan is ideal for street rods, classic cars, and marine applications, providing reliable cooling when you need it most.
