There are nearly endless uses for industrial fans all over the world. For example, they are commonly used for cooling or to move air from place to place. Whatever the case, It is important to understand the different options that you have to choose from and how they fit your application and operations. The two common options we will discuss in this article are axial fans and centrifugal fans. If you are not sure what design is best for you, there is no need to worry.

Now, let’s take a look at the best ways to choose between axial fans and centrifugal fans. To do this effectively, we will touch on some background information for each type and specific applications for each one as well.
WHAT ARE AXIAL FANS
Axial fans got their name from the way that they force air to move. Fan blades rotate around an axis, which causes the air to flow in a direction that is parallel to the axis. These blades can come in many different shapes and sizes depending on the specific use case. This will be influenced by things such as how much air needs to be moved and how quickly it needs to move. Some examples of the different blades shapes are paddle shaped, sickle shaped, variable pitch shaped, or air foil.
This axial airflow design is referred to as a high flow rate design. In other words, they will create a large volume of airflow. Even though these produce a large volume of airflow, this is done at low pressure.
These air handling fans are based on a simple design that dates back to the Middle Ages. Europeans began using this fan design for building some of the world’s first windmills. Much later, the axial fan design was used to create the first electrically powered fans in the late 19th century.
Now that we have a better understanding of how axial fans operate, you will probably guess that they are used in a large variety of different industries and applications. Let’s take a look at a few of those examples.
AXIAL FAN APPLICATIONS
Due to the large volume of airflow at low pressure created by the axial fan design, there are many ways these industrial fans can be used. Most of these uses will fall under the general purpose category. In other words, situations where you need to move air from one place to another. One example of this would be cooling. Moving hot air from one place to another in order to cool equipment or even cool a building such as your home or work place. Axial fans are also commonly used for condenser cooling in refrigeration systems.
Our partners such as New York Blower, has a reputation for having top of the line equipment and has many options to choose from. When paired with SES’s outstanding service, you will be sure to get the best axial fan setup on the market.
WHAT ARE CENTRIFUGAL FANS
The centrifugal fan design is another commonly used piece of air handling equipment. You will also hear them frequently referred to as blowers or squirrel cage fans because they resemble a hamster wheel. This fan design consists of a series of blades that are mounted on a circular hub and as they rotate, it forces air and other gases to move radially away from the fan. The direction of this air is typically changed by 90 degrees from the air coming into the unit.
Unlike the axial fan design, centrifugal fans operate at higher pressures. The fan wheel increases the pressure of the incoming air and usually moves the air through ducts or tubes that help maintain this higher pressure. Despite the higher pressure, this design operates at a lower flow rate with a more steady stream of air than the axial design.
There are also a few different centrifugal fan designs such as forward curves, backward inclined, radial, airfoil, and radial tip. It is important to know the differences and make a decision that is best for your specific operations. If you have any questions, SES will be able to point you in the right direction.
Centrifugal fans were first used in 1832 by a military engineer named Alexander Sablukov. He was a Lieutenant in the Empire Imperial Russian Army and is known for the invention of this fan design.
CENTRIFUGAL FAN APPLICATIONS
Since centrifugal air handling fans operate under a higher pressure environment, they are used for applications that require this higher pressure. A couple examples would be systems that are used for drying purposes. They are also effective when used in heating and air conditioning systems, boiler combustion air handling, and electronic cooling just to name a few.
This particular design is also useful when you are dealing with air that contains particulates or other pollution. Filtration systems within centrifugal fans are able to remove these particulates and allow the air to be moved efficiently.
SES teams up with Continental Fan Manufacturing Inc. to provide exceptional products and service in the centrifugal fan space. If you have any questions, our team of experts will be able to point you in the right direction.
SES WILL HELP YOU MAKE THE RIGHT DECISION
As you can see, axial fans and centrifugal fans are both great options and have their own advantages. However, it is important to choose the right industrial air handling fan design for your application.
For a quick recap, axial fans are designed for high volume and low pressure. They work best for general purpose applications such as moving air from one place to another or cooling large and small areas.
Centrifugal fans are an enclosed design that use a lower volume of air and higher pressure. This type is best for heating and cooling or particulate handling applications.
No matter what your specific scenario is, SES will work with its partners like New York Blower and Continental Fan Manufacturing Inc. to provide you with an effective and efficient solution. Please contact us today to discuss your options and choose the best solution for your project.
