Forward curve sometimes referred to as a squirrel cage fan forward curve fans are used in most residential and light commercial hvac equipment.
Forward curved centrifugal fan diagram.
They are the most budget friendly and the least efficient blade design.
Sometimes centrifugal fans are called radial flow type fans.
These fans are for low to medium static applications.
Centrifugal fans are capable of generating relatively high pressures.
Wheel types centrifugal fans may be classified into three basic types according to blade configuration.
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.
Generally centrifugal fans have three types of blade.
A forward curved centrifugal fan works best when high pressures against lower volume flows are required.
They are suitable for high pressure applications as compared with axial flow fans.
Forward blade backward blade and radial blade.
The characteristic curve of.
Typical centrifugal fan and covers the common terminology of these components.
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.
