Derale Heavy Duty Flex Fans

Product images may differ from actual product appearance.

Derale Heavy Duty Flex Fans provide maximum airflow at low RPM when vehicle speeds provide little to no air through the radiator. Vehicle speed offers ample flow at higher RPM so fan blades flatten to minimize engine loading, increasing horsepower and mileage. Fan spacer sold separately.

Features & Benefits
  • Heavy Duty steel hubs
  • Durable stainless steel blades
  • Rated up to 10,000 RPM
  • Improves performance and mileage
  • Large surface area pulls more air at low speeds
  • Reinforced blade construction extends fan life
