    The Derale 19318 is an 18" high performance flex fan with stainless steel blades and a black hub, built for reverse-rotation water pumps found on many serpentine-belt engines. Its flexible stainless blades flatten as engine speed rises to reduce fan drag and noise at higher rpm while still moving strong airflow at idle and low speed. It is a universal mechanical fan for reverse (counterclockwise) rotation applications.
