13in Rigid Race Fan (Alu minum Blade)

The 13in Rigid Race Fan with aluminum blade from DERALE is purpose-built for high-performance cooling in competition and modified vehicles where space and weight matter. This rigid fan is engineered for serious enthusiasts and mechanics who demand reliable thermal management without the drag penalties of belt-driven viscous fans. Whether you're running a track-focused engine build, upgrading a street rod, or optimizing cooling flow in a tight engine bay, a fixed-blade race fan eliminates the parasitic loss associated with thermal clutches and provides consistent airflow at all RPM ranges.

The aluminum blade construction delivers a critical advantage in lightweight performance applications: reduced rotational inertia means faster response to thermal demand and minimal horsepower steal from the accessory drive. The 13-inch diameter is sized for compact installations common in mid-size radiators and custom cooling setups, offering a balance between airflow volume and packaging constraints. DERALE's rigid design means this fan runs at engine speed without modulation, making it ideal for dedicated race cars, engine dyno testing, or hot rod builds where engine bay temperatures run consistently high and variable cooling demand is minimal. The fixed-blade geometry is optimized for straight-through airflow efficiency.

This configuration suits builders with carbureted or naturally aspirated platforms where conventional belt-driven fans create unnecessary drag, as well as those converting to electric cooling or hybrid setups. Verify your radiator shroud diameter and frame clearance before installation, as 13-inch fans require adequate mounting space. The aluminum blade won't rust or corrode and resists debris damage better than plastic alternatives, making it reliable in high-heat environments. Installation typically involves standard fan spacer and bolt-down mounting to existing fan clutch hubs or adapter plates.
