An important consideration in fan sizing is the location of operating points on a fan's performance curves. Figure 1 shows a typical fan curve with a fan's corresponding total efficiency. The fan curve indicates how a fan will perform at various pressures at a constant speed. The fan's highest efficiency (shaded green) corresponds with the operating points located on the top half of the fan-pressure curve. A fan operating higher on a fan curve generally is going to be more ...
