    The Derale 19917 is a 17 inch high performance flex fan for belt-driven engine cooling. Its aluminum flexible blades, finished in blue, flatten out as engine rpm rises to reduce the power the fan draws at speed while still moving strong airflow at idle and low speeds. The fan uses a black hub and turns in the standard clockwise rotation used by most V-belt and serpentine water pump setups.
