Types Of Centrifugal Fans

Basic types of centrifugal fans.

Types of centrifugal fans.

They are ideal for high pressure applications quite different from the other type of fans known as the axial fans. Types of blades used in centrifugal fans are. Centrifugal fan blade types. Such a fan is also called a blower fan biscuit blower citation needed or squirrel cage fan because it looks like a hamster wheel.

In a mixed flow fan the air flows in both axial and radial direction relative to the shaft. 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. Forward blade backward blade and radial blade. They are suitable for high pressure applications as compared with axial flow fans.

Below are the six most common types of centrifugal fans each with a unique blade configuration. Centrifugal fans are capable of generating relatively high pressures. Radial bladed fans are best for industrial applications where there is dust or in environments where there is gas or moisture in the air. Straight steel plate paddle wheel.

Mixed flow fans. The different blades can be characterized as shown in the capacity diagram below. 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. 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.

The characteristic curve of three kinds of centrifugal fan is shown in figure 2 15. Pti a global leader in fan technology for more than 25 years manufactures both axial and 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. Types of centrifugal fans blowers.

Axial vs centrifugal 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. 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. Our application engineers design all of the centrifugal fan and blower components to accommodate an application.

The blade wheel are mounted in housing and the blades can be forward curved straight or backward curved. Centrifugal fans come in a variety of designs. There are two primary varieties of fan axial fans and centrifugal fans. Centrifugal fans often contain a ducted housing to direct outgoing air in a specific direction or across a heat sink.

To help clear up that confusion here is a breakdown of the fan types their benefits and their uses. In addition the blades curve in the same direction as the rotation of the wheel. 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.
