Centrifugal blowers, also known as centrifugal fans, are used in a wide range of industrial applications to move large volumes of air or gas. They are popular in the manufacturing industry, particularly in ventilation systems and air conditioning systems, such as combustion air blowers, furnace blowers, and draft inducers. In this guide, we will explore what centrifugal blowers are, how they work, the different types of centrifugal blowers available, their applications, and their benefits.

As one of the leading centrifugal blower manufacturers in Taiwan, Air Deviser Industrial proudly produces centrifugal blowers. We are happy to share knowledge of them with you.

What is a Centrifugal Blower?

Centrifugal blowers are a type of mechanical device used to move air or gas continuously in a specific direction (normally 90 degrees). Centrifugal blowers consist of an impeller, housing, inlet and outlet ducts, and a drive mechanism (motor). These blowers work on the principle of kinetic energy conversion into potential energy and are widely used in various industrial and commercial applications. The working principle of centrifugal blowers is based on the kinetic energy of the impellers, which is utilized to move the air stream.

How Does a Centrifugal Blower Work: Working Principles

Air or gas enters the impeller blades of the blower, and as it flows through the blades, it is accelerated toward the outer edges. As the air or gas moves towards the periphery, it encounters the volute casing, which diffuses the air or gas and converts the kinetic energy into pressure static. The air or gas is then expelled through the outlet.

Centrifugal blowers are generally used for ducted applications that either extract air through channels or heat exchangers or push air through similar systems.

Types of Centrifugal Blowers

There are four main types of centrifugal blowers: forward-curved, backward-curved, radial, and airfoil.

●  Forward-Curved Blowers



▲Check out our forward-curved blowers - AD200A Centrifugal AC blowers, it has high revolution speed (2800rpm ~ 3400rpm).

Forward-curved blowers, also known as squirrel cage blowers. They are characterized by their curved blades, which are arranged in a circular pattern around a central hub. These blowers have blades that are curved in the same direction of rotation of the fan wheel. and are best suited for low-pressure applications. They are commonly used in printing machines, kitchen hoods, clean room equipment, packing machines, UV dryers, and air showers, as well as for air suction, discharging, ventilation, furnace blowers, heaters, and HVAC systems for air induction and circulation.

●  Backward-Curved Blowers


▲Check out our backward-curved blowers - AD050BCP Combustion Air Blowers

Backward-curved blowers have blades that are curved in the opposite direction of rotation. They are more energy-efficient than radial and forward-curved blowers. They are ideal for low air flow and high-pressure applications. Commonly used as a combustion air blower in factories or power plants to burn fuels and gas. They can move large volumes of air at high static pressures. Besides, they are widely used in small boilers, machinery, stove, air conditioner, baking machine, kitchen hoods, laboratories, dust collectors, odor control systems, air handling units, fume extraction systems, emission control systems, heat recovery systems, and many more.

● Radial Blowers


▲Check out our radial blowers - AD279DS Furnace Blowers. Its 3-Sectional speed design provides different options making the fan operate more efficiently.


Radial blowers, also known as paddle wheel blowers. Their radial impellers are made up of a series of flat blades that rotate around a central shaft. These blowers have simple designs and blades that are straight and extend radially from the center of the impeller, making them suitable for high-volume applications.


● Airfoil Blowers

Airfoil blowers are with airfoil-profiled blades that are commonly used in industries with high temperatures, such as chemical, power generation, and metalworking. These fans are known for their high efficiency and quiet operation, but they are not suitable for dusty environments.


Applications of Centrifugal Blowers

Centrifugal blowers are used in a wide range of industrial applications. They are commonly used in ventilation systems, HVAC systems, pneumatic conveying systems, and combustion air systems. They are also used in industrial processes such as drying, cooling, air handling, and dust collection. Different types of blowers also have different uses.

Advantages and Disadvantages of Centrifugal Blowers

Advantages

Centrifugal blowers offer several benefits over other types of fans and blowers:


● High efficiency: Centrifugal blowers are highly efficient and can move large volumes of air or gas with minimal power consumption.

●  Low noise levels: Centrifugal blowers operate with minimal noise levels, making them suitable for noise-sensitive environments. produce less noise than other types of fans and blowers.

●  Low maintenance: These blowers require minimal maintenance due to their robust design and durable construction. This translates to reduced downtime and lower repair costs, making them a cost-effective choice in the long run.

●  Cost-effective: Compared to other types of fans and blowers, centrifugal blowers often offer a lower cost of installation and operation.

●  Consistent volume delivery: Centrifugal blowers can deliver a large volume of air or gas consistently, with minimal turbulence. This allows for reliable and uniform airflow, ensuring efficient ventilation and cooling in various applications.

Disadvantages

● Space limitations: Centrifugal blowers may not be suitable for tight or compact spaces due to their physical size and design. Sufficient space must be available for installation and proper airflow.


● Efficiency at low speeds: Centrifugal blowers may experience reduced efficiency when operated at low speeds. It is important to consider the specific requirements and airflow demands of a system to ensure the blower operates within its optimal range.

The advantages of high efficiency, low noise levels, low maintenance, energy efficiency, cost-effectiveness, and consistent volume delivery make centrifugal blowers a popular choice in various industrial and commercial applications. However, it is essential to be mindful of space limitations and efficiency requirements for optimal performance. It is suggested to ask for assistance from an experienced manufacturer like Air Deviser Industrial when choosing one.

Conclusions

Centrifugal blowers play an important role in various industrial applications. They work based on the principles of centrifugal force and come in four main types: radial, forward-curved, backward-curved, and airfoil. They are commonly used in ventilation systems, HVAC systems, and industrial processes. Centrifugal blowers offer several benefits over other types of fans and blowers. With various types of centrifugal blowers available, each with its own unique design and application. It is important to choose the right blower for your specific needs.
