Forward Curved Centrifugal Fan Diagram

Wheel types centrifugal fans may be classified into three basic types according to blade configuration.

Forward curved centrifugal fan diagram. The characteristic curve of. Figure 1 centrifugal fan figure 2 axial fan each fan system has different types of wheels or impeller types. These fans are for low to medium static applications. Radial or straight blade each type has its own application range and limits.

Sometimes centrifugal fans are called radial flow type fans. The video below discusses small low pressure centrifugal fans which can move air quickly at a pressure between about 100 and 2 000 pascals. The graph below illustrates the optimum working area the volume flow is plotted along the x axis and the system pressure is plotted on the y axis. Centrifugal fans are capable of generating relatively high pressures.

The most important thing to know is that backward curved blades are the most efficient whereas forward curved blades are one of the least efficient types of fans. A forward curved centrifugal fan works best when high pressures against lower volume flows are required. Typical centrifugal fan and covers the common terminology of these components. They are the most budget friendly and the least efficient blade design.

They are suitable for high pressure applications as compared with axial flow fans. Generally centrifugal fans have three types of blade.
