18in Rigid Race Fan (Ste el Blade-Rvrse Rot.)

The 18in Rigid Race Fan with steel blade and reverse rotation by DERALE is purpose-built for high-performance automotive cooling applications where space, airflow efficiency, and durability matter. Whether you're running a competition engine, a heavily modified street machine, or any application demanding serious cooling capacity, this rigid fan delivers consistent thermal management without the parasitic drag of belt-driven alternatives. Race-proven by serious enthusiasts and fabricators, the reverse-rotation configuration allows flexible installation options that maximize cooling system packaging in tight engine bays.

Steel blade construction provides superior durability and fatigue resistance compared to plastic-blade alternatives, especially critical in high-vibration environments or when running aggressive fan speeds. The rigid mounting design eliminates flex and wobble, ensuring consistent blade geometry and peak airflow performance across the entire operating range. At 18 inches in diameter, this fan strikes the ideal balance between substantial CFM output and practical installation dimensions—measuring 19.7 x 3.55 x 22.2 inches overall and weighing just 5.48 lbs, it's light enough for carbureted or EFI swap applications without adding excess unsprung weight.

This fan excels in custom cooling setups for street rods, muscle cars, track-focused builds, and any scenario where OEM fan performance falls short or packaging constraints limit factory options. The reverse-rotation feature is particularly valuable when integrating aftermarket radiators or repositioning the cooling system in engine bay modifications. Installation typically requires a shroud setup and either electric motor or belt-drive adapter; verify your specific application's pulley diameter and motor compatibility before purchase. Preferred by fabricators and performance shops for its reliability and straightforward integration into custom cooling circuits.
