Horton’s new WindMaster plastic MS9 fan is an aerodynamically shaped nine-blade fan designed for class 5, 6 and 7 truck and bus applications. The fans are available in both clockwise and counterclockwise rotation with diameters from 22 to 30 in. (560 to 762 mm). The pitch width is 3.62 in. (92 mm) and standard mounting pilots range from 2 to 5 in. (51 to 127 mm). This lightweight fan delivers greater airflow with improved efficiency, Horton says. The hubless fan has a hexacomb pattern on the center section for improved stacking ability and reduced shipping and storage costs.
