Mechanical Flex Fans

Automotive or radiator cooling fans are a necessity, but they can also rob power when you need it most. Flexible, or Flex Fans might be the answer. When you're driving at low RPM you need your fan to pull air across the radiator to keep your engine cool. When your moving down the highway or track, there is plenty of air moving across the radiator. Flex fans are made to keep their shape up to a certain RPM. As an engine reaches that RPM level, the fan blades flatten out reducing the air pull. A "flat fan" is much easier to turn because it has no drag. As engine RPM's slow down, the flex fan will regain its shape to pull air again. A simple radiator cooling fan solution!
