Centrifugal fans are a special type of industrial fans used in several process industries and air pollution systems centrifugal fans are also called as blowers.
Types of centrifugal fans.
Basic types of centrifugal fans.
Centrifugal fans come in a variety of designs.
The different blades can be characterized as shown in the capacity diagram below.
Straight steel plate paddle wheel.
The blade wheel are mounted in housing and the blades can be forward curved straight or backward curved.
Radial bladed fans are best for industrial applications where there is dust or in environments where there is gas or moisture in the air.
Below are the six most common types of centrifugal fans each with a unique blade configuration.
In addition the blades curve in the same direction as the rotation of the wheel.
Backward curved blades are generally more efficient but forward curved blades are more self cleaning and should be used in applications with high dust concentrations.
Generally centrifugal fans have three types of blade.
Mixed flow fans.
The characteristic curve of three kinds of centrifugal fan is shown in figure 2 15.
Centrifugal fans often contain a ducted housing to direct outgoing air in a specific direction or across a heat sink.
Centrifugal fans come in four basic fan types each with its own specific purpose.
Some common design criteria are the size of the motor the shape of the fan blade the direction of rotation and the materials of construction.
Centrifugal fans often called as blowers are special type of industrial fans that are ideal for high pressure applications in several process industries and air pollution systems.
A centrifugal fan is a mechanical device for moving air or other gases in a direction at an angle to the incoming fluid.
Centrifugal fans increase the pressure of an incoming airstream by impellers a series of blades mounted on a circular hub which in turn accelerates air radially.
They are suitable for high pressure applications as compared with axial flow fans.
The centrifugal fans operates by throwing air away from the blade tips.
Types of centrifugal fans blowers.
Pti a global leader in fan technology for more than 25 years manufactures both axial and centrifugal fans.
Axial vs centrifugal fans.
They are ideal for high pressure applications quite different from the other type of fans known as the axial fans.
Radial these are high pressure fans with medium airflow.
Centrifugal fan blade types.
To help clear up that confusion here is a breakdown of the fan types their benefits and their uses.
There are two primary varieties of fan axial fans and centrifugal fans.
Our application engineers design all of the centrifugal fan and blower components to accommodate an application.
In a mixed flow fan the air flows in both axial and radial direction relative to the shaft.
Forward blade backward blade and radial blade.
Forward curved fan also known as a squirrel cage fan due to the wheel type this fan s impeller is forward and somewhat small.
