Understanding the limitations of fan efficiency grades
Understanding the limitations of fan efficiency grades

Fan efficiency grades (FEG) are a poor metric in determining the most efficient fan (in terms of actual power consumption) for a given airflow and pressure operating point. The best simple metric to ensure the lowest power consumption is the operating brake horsepower at the specified design point. Read More
