Forward Curved Centrifugal Fan Diagram

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.

Forward curved centrifugal fan diagram.

Forward curve sometimes referred to as a squirrel cage fan forward curve fans are used in most residential and light commercial hvac equipment. Radial or straight blade each type has its own application range and limits. The characteristic curve of. They are suitable for high pressure applications as compared with axial flow fans.

Centrifugal fans are capable of generating relatively high pressures. Sometimes centrifugal fans are called radial flow type 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.

Figure 1 centrifugal fan figure 2 axial fan each fan system has different types of wheels or impeller types. 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. They are the most budget friendly and the least efficient blade design. Wheel types centrifugal fans may be classified into three basic types according to blade configuration.

These fans are for low to medium static applications. The centrifugal fans with forward curved blades 2l 90 o are designed due to the small dimensions and good static pressure characteristics of fans and such a recommendation refers to the fans.
