Everything You Need to Know About the Industrial Axial Flow Fans

Are you confused between the industrial axial flow fans and the centrifugal blowers or fans? Well, don’t worry! We have been there too. That’s why we understand how confusing these two fans can be. For this reason, we have prepared this comprehensive guide for you. Here, we will tell you everything you need to know about the axial flow fans, their types, and their advantages. So, make sure you stick right through the end!

What Are The industrial Axial Flow Fans?

For those of you who don’t know, axial flow fans are one of the main types of industrial fans. The main function of these fans is to cool down the equipment and machines that heat up after you use them. Thus, it will not be wrong to say that these fans are like the compressor that produces airflow parallel to the axis. Not only this, but these fans come with impellers as well. The impellers play an important role in sucking the air in and discharging it in the same direction of the axis.

An important thing to remember here is that there are both AC and DC axial flow fans available in the market. A great thing about them is that you can get them designed in different ways such as with a mounting ring or a duct upon your requirement.

Thus, there are different standing designs available on which you can customize your device and the installation type. You can also decide the materials and accessories that you want in the fan. However, you should decide on these materials and accessories based on the environment where these fans would be exposed. In addition to this, you should also consider the pressure, temperature, and moisture in the given area.

The Working of the Industrial Axial Flow Fans

The working of the industrial axial flow fans is quite straightforward once you get hold of it. Their working is a lot similar to an aircraft wing which contains an airfoil shape and produces lift. The airfoil shape of the wing helps the fans to divide the air above and below into different velocities.

The reason behind it is that the air that is present above the section travels far than the air that is present below. The above air has a high velocity which helps it in producing a low static pressure and a dynamic force.

On the contrary, the air that is present in the bottom section produces high static pressure and has low velocity. Due to the pressure differences between both the airs, a lift forms.

The blade of the axial flow fans act like wings and push the air forward. As a result, a lift is formed. This lift plays an important role in propelling the air and pushing it back. The speed of the wind continues increasing to the point that it leaves the fan. That’s why you get a greater airflow at the exit than at the entry point.

Components of the Industrial Axial Flow Fans

The motor is the most basic and important part of all the axial flow fans out there. Apart from the motor, the fans have blades, impellers, and bearings as well.

The housing or the enclosure of the fan helps to protect it against external damage such as shock, damage, spillage, vibration, etc. For this reason, you need to construct the enclosure from strong and durable materials such as steel, alloys, or aluminum.

The majority of the impellers use cast aluminum that has black paint, steel, or thermoplastic. This is important so that the impeller stays corrosion resistant.

On the other hand, thermoplastic is not an ideal material for impellers in commercial applications. Therefore, their use is widely popular in residential applications.

Coming to the propellers, they feature blades. These blades on the propellers can range from two to twenty in number. You can connect the fan to a motor drive in the housing parallel to the direction of the airflow. In the majority of the cases, the blades are made using aluminum.

These fans are designed in such a way that they can resist extreme temperatures, shocks, flames, corrosive materials, and other harmful things.

Some common accessories come with these fans as well. These accessories include a silencer, connecting points, vibration controller, counter flange, protection grill, and so on.

Benefits of Using Axial Flow Fans In the Industry

Using the axial flow fans in the industry can offer you many benefits over the other industrial fans. Want to know what those benefits are? Keep reading then.

1.      Durable Construction

One of the major advantages of industrial axial fans is that they are made of aluminum and it is common knowledge that aluminum is one of the most durable, lightweight, reliable, and user-friendly materials out there. In some cases, people also use stainless steel in their construction. Stainless steel plays a major role in improving the performance of these fans in harsh environments.  Thus, you can easily expect these industrial fans to last for years.

2.      Easy to Maintain

The axial flow fans are extremely easy to maintain. That’s because their design is a lot simpler than other industrial fans out there. As a result, the operational issues that arise can be easily identified and corrected. This is one of the primary reasons that these fans are popular in exhaust applications and industrial cooling.

3.      Offer Variable Speed

You can easily alter the speed of the axial flow fans to suit the needs of your exhaust fans or cooling tower. Even if you decrease their speed, these fans will continue producing high airflow. This is what sets them apart from other industrial fans.
