Centrifugal Blowers

A centrifugal blower is a pump or motor that moves air. It pulls the air inside the blower and then pushes it out at a 90º angle. Often centrifugal blower is mistaken as a centrifugal fan. However the distinction between a fan and a blower lies in the amount of pressure that they can produce. So any centrifugal fan that can produce pressures that are greater than 1.2 mg/cm2 at a high flow rate is considered a centrifugal blower.

The centrifugal blower is designed and developed using quality stainless steel and mild steel sheets. It has impellers which rotate to increase the speed and volume of the air stream. They exert air from the inlet and then release it through the outlet at the angle of 90 degrees. A centrifugal blower is employed in industries, factories and various other places where there is emission of air and harmful gases. It is used for resisting the dampers, ducts and other components in the air and gas pressure. It is mostly used by the HVAC industry.

The main features of centrifugal blowers can be summarized as: maintenance free blower, rugged and corrosive resistant surface finish, low power consumption, high air flow and 100% oil free air, easy installation, high durability, and stable running.

Centrifugal blowers are very useful for industries that require larger volumes of gas and air flow at higher pressures. They are often used in building ventilation systems, air pollution control systems and also for industrial processes to transport gas or materials. Here are some applications of centrifugal blowers:

• Air conditioning
• Heating and room cleaning
• Fume extraction
• Dust collection
• Material conveying
• Drying
• Ventilation purpose 

There are several different types of centrifugal blowers, and each one has its own features, load bearing capacity and pros and cons. The commonly used centrifugal blowers are: radial blade blowers, airfoil blade blowers, radial tip blowers, and inline centrifugal blowers.
