The DERALE 18in Rigid Race Fan Steel Blade is a mechanical cooling fan engineered for high-performance engine cooling in vehicles where consistent thermal management is critical. Built with six steel blades and a 5/8-inch pilot hub, this rigid fan mount delivers reliable airflow in demanding conditions where flexible or electronic fan solutions may not meet durability or responsiveness requirements. The black powder-coat finish provides corrosion resistance for extended outdoor and off-road use.
Rated at 18 inches in diameter with a universal bolt pattern mount, this fan accommodates a wide range of engine block configurations without requiring custom fabrication. The six-blade design balances airflow volume with mechanical efficiency, drawing heat away from the radiator core during high-load operation. Steel construction provides superior impact resistance compared to plastic alternatives, making it suitable for vehicles operating in rough terrain or exposed to road debris. The 5/8-inch pilot ensures proper centering on standard water pump shafts, critical for minimizing vibration and extending bearing life during sustained high-RPM operation.
This fan is designed for off-road vehicles, race support equipment, and engine builds where mechanical reliability and thermal performance take priority over compact packaging. Operators managing vehicles in extreme climates, high-altitude environments, or sustained towing scenarios benefit from the mechanical engagement—no electronic controller or fluid coupling to fail under load. The universal mounting pattern simplifies installation across diverse engine platforms, reducing lead time for custom builds and maintenance swaps in field conditions.
Weighing 5.45 lbs and measuring 19.8 x 3.55 x 22.2 inches, this rigid race fan integrates into engine compartments with minimal clearance impact. Whether specified for recovery vehicles, off-road platforms, or performance marine engines, the DERALE 18in model provides predictable, maintenance-friendly cooling without complexity.
