Forward curved centrifugal fan diagram.

These fans are for low to medium static applications. 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. The characteristic curve of.

Radial or straight blade each type has its own application range and limits. Generally centrifugal fans have three types of blade. 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. A forward curved centrifugal fan works best when high pressures against lower volume flows are required.

Wheel types centrifugal fans may be classified into three basic types according to blade configuration. Centrifugal fans are capable of generating relatively high pressures. The video below discusses small low pressure centrifugal fans which can move air quickly at a pressure between about 100 and 2 000 pascals. Typical centrifugal fan and covers the common terminology of these components.

They are suitable for high pressure applications as compared with axial flow fans. Forward curve sometimes referred to as a squirrel cage fan forward curve fans are used in most residential and light commercial hvac equipment.
