WINDMASTER FANS Now Available With 11 Blades WindMaster fans are designed to meet the higher performance standards of today’s diesel engines.  The design moves more air while actually drawing less horsepower! The WindMaster’s airfoil and blade design can increase airflow by 15 percent, draw 20 percent less horsepower and maintain blade shape at high RPMs. That means maximum cooling performance, easier starts, less wear on the fan, and better fuel economy. The 9 blade fan honeycomb hub structure and the 11 blade honeycomb mounting pilot provide maximum durability without extra weight. With 22"-34" diameters, and eight, nine or eleven blade options, it fits most heavy-duty applications. Whether installed at an OEM, or retrofitted into an existing engine, the WindMaster is designed to help the most demanding diesel engines keep their cool.
