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