17in Stainless Fan

The 17in Stainless Fan (MPN 19117) from DERALE is a mechanical flex-blade cooling fan engineered for universal automotive applications where engine bay temperatures demand reliable thermal management. Built for mechanics and enthusiasts who need dependable auxiliary cooling without electronic complexity, this six-blade fan delivers consistent airflow across a wide range of engine speeds and operating conditions. Whether upgrading a classic restoration, supporting a high-output engine build, or addressing marginal factory cooling, the 17in Stainless Fan solves thermal issues with proven mechanical design that requires no electrical wiring or sensor management.

This fan features six stainless steel blades bonded to a steel hub, offering superior corrosion resistance and blade durability in harsh underhood environments. The flex-blade design automatically adjusts blade pitch as engine RPM increases, allowing the fan to draw air efficiently at idle while reducing parasitic drag at highway speeds—this self-regulating behavior improves cooling without taxing engine power. The 5/8-inch pilot bore and universal bolt pattern integrate with most radiator shroud assemblies, making installation straightforward for custom and OEM applications alike. At 2.95 pounds and measuring 17 inches in diameter with a 2-inch depth, the unit fits tight engine bays while delivering the airflow volume needed for high-horsepower builds and heavy-duty cooling demands.

This mechanical cooling fan benefits street rods, muscle cars, trucks, and engine swaps where space constraints or electrical simplification favor passive solutions. Mechanics favor it for late-model conversions into older frames, diesel auxiliary cooling, and any build where eliminating parasitic electrical load matters. Verify radiator shroud compatibility and mounting boss spacing before purchasing; the universal bolt pattern accommodates most applications, but hub height and blade clearance should be confirmed against your specific fan shroud. The stainless construction resists rust in damp climates and delivers years of reliable service without thermostat or relay dependency.
