Types of centrifugal fans blowers.
Types of centrifugal fans.
A centrifugal fan is a mechanical device for moving air or other gases in a direction at an angle to the incoming fluid.
Pti a global leader in fan technology for more than 25 years manufactures both axial and centrifugal fans.
The centrifugal fans operates by throwing air away from the blade tips.
The characteristic curve of three kinds of centrifugal fan is shown in figure 2 15.
Our application engineers design all of the centrifugal fan and blower components to accommodate an application.
There are two primary varieties of fan axial fans and centrifugal fans.
Generally centrifugal fans have three types of blade.
Below are the six most common types of centrifugal fans each with a unique blade configuration.
Centrifugal fans come in four basic fan types each with its own specific purpose.
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.
The different blades can be characterized as shown in the capacity diagram below.
The blade wheel are mounted in housing and the blades can be forward curved straight or backward curved.
Centrifugal fans are capable of generating relatively high pressures.
They are ideal for high pressure applications quite different from the other type of fans known as the axial fans.
Forward curved fan also known as a squirrel cage fan due to the wheel type this fan s impeller is forward and somewhat small.
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.
They are suitable for high pressure applications as compared with axial flow fans.
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.
Such a fan is also called a blower fan biscuit blower citation needed or squirrel cage fan because it looks like a hamster wheel.
Forward blade backward blade and radial blade.
To help clear up that confusion here is a breakdown of the fan types their benefits and their uses.
Radial bladed fans are best for industrial applications where there is dust or in environments where there is gas or moisture in the air.
Basic types of centrifugal fans.
In a mixed flow fan the air flows in both axial and radial direction relative to the shaft.
Mixed flow fans.
Straight steel plate paddle wheel.
In addition the blades curve in the same direction as the rotation of the wheel.
Types of blades used in centrifugal fans are.
Centrifugal fans come in a variety of designs.
Centrifugal fan blade types.
Centrifugal fans often contain a ducted housing to direct outgoing air in a specific direction or across a heat sink.
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.
