Centrifugal Blower Fan Design

Centrifugal fans are widely used for many and various commercial and industrial applications today.

Centrifugal blower fan design.

It is important to recognize that the design of any turbo machine is an interdisciplinary process involving aerodynamics thermodynamics. A centrifugal fan is a mechanical device for moving air or other gases in a direction at an angle to the incoming fluid. Fans and blowers bureau of energy efficiency figure 5 1 centrifugal fan figure 5 2 axial fan centrifugal fan. And a higher power requirement on the intake usually equates to more power generated on the other end too.

Centrifugal fans come in a variety of designs. Single unspared centrifugal compressor trains support the entire operation of steam crackers producing in excess of 1 000 000 metric tons approximately 2 2 billion lbs of ethylene per year. Centrifugal compressors blowers and fans form the basic make up of unspared machinery equipment in petrochemical process plants. Centrifugal fans and blowers have wheel designs for most airstream constituents and a broad pressure and volume capability.

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. For the article we will be investigating the different design characteristics of centrifugal blowers. Centrifugal fans require more power to run but gas engines provide power in spades. Professional grade gas powered motors tend to be mounted to a backpack style harness.

Centrifugal fan design methodologies 3 1 introduction centrifugal fans and blowers are the turbo machines widely used in present industrial and domestic life. Centrifugal fans often contain a ducted housing to direct outgoing air in a specific direction or across a heat sink. Such a fan is also called a blower fan biscuit blower citation needed or squirrel cage fan because it looks like a hamster wheel. Types the major types of centrifugal fan are.

Types of centrifugal fans blowers. Centrifugal fans have excellent aerodynamic qualities high efficiency levels and are capable of reaching up. Radial forward curved and backward curved see figure 5 3. Radial fans are industrial workhorses because of their high static pressures upto 1400.

Our application engineers design all of the centrifugal fan and blower components to accommodate an application. As well many design parallels exist between high pressure blowers and compressors.
