Optimised for cooling tower use The SFC Series was specifically designed for the cooling tower environment. Use the chart to find the correct size based on motor Motor Size vs. Fan Speed *Refer to the selection table on page 5 for detatils Extended Bearing Span Even if the cooling fan is balanced, excess vibration can occur during operation. Using an extended fan drive shaft (gearbox low speed shaft), run-out due to fan operation is significantly reduced. Balanced Mounting Load By arranging the mounting bolt holes uniformly about the fan drive shaft, the load to the gearbox mounting base is...
