WebUnderstanding Fan Curves angle propeller fans and forward curve centrifugal fans. In contrast, compare this curve to Figure 2, which rep-resents a typical curve for a backward inclined centrifu-gal fan. This curve shape is also representative of radial blade centrifugal fans. Note the lack of a pronounced dip on this curve. WebThe static pressure curve for the fan therefore goes down, as shown in Figure 6.27. The rate of reduction for the box impedance curve is the same as the rate of reduction for the fan static pressure curve, so the two curves cross the same CFM flow point. As a result, the CFM flow through the box remains approximately constant as the
