A centrifugal fan is among the most energy-efficient fans available today. Most people consider a centrifugal fan to be nothing more than a fan; its complexities are not widely known. These fans push air outward through ducts or tubes, providing a stronger and more consistent airflow than axial fans. A centrifugal fan is commonly used in domestic applications to move air through a duct. For example, consider your air conditioner, furnace, or stove hood duct. Centrifugal fans are into four categories, each with a distinct purpose.
These are medium-flowing high-pressure fans. Radial-bladed fans are ideal for dusty industrial applications or settings with gas or moisture in the air. The blower fan can transport both granular and stringy materials. These fans are normally composed of the heavy-gauge plate and have six or eight blades. They generate pressure at high tip speeds and can sustain more vibration, unbalanced forces, and impact than conventional fans.
These are fans with high pressure, high flow, and great efficiency. Power decreases as flow increases over the most efficient section of the system. Although the BC wheel is for clean air applications, it frequently meets light dust in the airstream. It has curved intake cones and side rims on the wheel to control airflow through the wheel more precisely. These characteristics also lead to extremely efficient air movement. The BC is the most susceptible to installation conditions of the three types.
These are medium-pressure, high-flow fans that you can utilize for clean air, ventilation, and exhaust. These blower fans have a lot of blades with a lot of curvatures and a short chord length. As a result, the air coming off the blades has a relatively high forward velocity vector. As a result, the fan speed is low.
These are the most efficient fans and work best in pure air situations. The efficiency of a centrifugal fan can depend on the type of fan blade it has. In this case, the airfoil is the best and most efficient.
Aerofoil designs give maximum efficiency (up to 10% greater than rearward curved blades) among centrifugal fan designs. However, its use only goes up to clean, dust-free air. In addition, axial-flow fans produce less pressure than centrifugal fans. They also demonstrate a pressure drop before reaching peak pressure.
Centrifugal fans are among the most efficient and adaptable types of air-moving equipment. Therefore, you need to be careful when choosing one. To select the proper fan, you must first determine how much pressure you need to achieve the specified airflow through the ducting and any filters, dampers, or other obstructions in your ventilation system. For example, you’ll require much more power if you have a long, intricate duct system.

There are more industrial applications for fans than most people can even imagine. Where do you even start in order to learn the differences between types of fans?
That’s easy. We’ve got you covered.
There are two main types of industrial fans. Differentiating between the two is easy once you understand how each type of fan works and what its benefits and limitations are.
This guide will help you answer the question of “Centrifugal fan vs axial fan?” Read on find out the big differences between the two most popular types of industrial fans.
The first and oldest option for an industrial fan is an axial fan. Here’s all you need to know about it.
Axial fans have been around forever. They’re the oldest design of a fan. These devices date back to the windmills designed by Persians in A.D. 500.
Engineers introduced the electrically powered fans to the public in the 1880s. These electric fans had the same design as the Persian windmills — an axial fan.
An axial fan is called “axial” because it has blades that rotate around a fixed axis. The fan is named for the direction of the airflow that it creates as it moves air.
The blades that rotate around the axis pull air in parallel to the axis and force it out in the opposite direction — still parallel to the axis.
Imagine a ceiling fan. There’s one fixed point in the ceiling that the fan blades rotate around. The fan draws air down from the ceiling, parallel to the axis, and forced straight down to the floor.
The airflow remains parallel to the axis of the fan for the entirety of the flow.
Axial fans don’t require a lot of power input in order to run. They move air at a high flow rate, meaning that they can move a lot of air. However, the airflow is low pressure.
Axial fans have a lot of uses, with most of them falling under the general purpose category. Consider one anytime you need to move a large volume of air from one place to another.
Low-pressure, high-volume flow is great for cooling spaces, such as a home or office building. It’s also great for cooling equipment, like the computer you’re using right now.
An axial fan is used in condenser cooling for a refrigeration system. It can also make a great exhaust fan.
As more technology is incorporated into everyday products, axial fans become more and more common. They are now used in vending machines to cool the computers that allow for cashless payment options.
For non-ducted applications, this model is likely the solution you need for airflow. Axial fans move a lot of air from place to place when working against little pressure.
The alternative option for an industrial fan is a centrifugal fan. Check out some quick facts on centrifugal fans to see if it’s right for you.
The centrifugal fan was invented in 1556 to ventilate mines. It disappeared from history after that. The design made a resurgence in the early 1800s.
Centrifugal fans are sometimes called blowers because they create a high-pressure stream of air.
A centrifugal can contains blades mounted around a circular hub. The motion of the hub pulls air in and around the hub, increasing the air pressure as it goes.
These devices move air radially. The end result is that the air coming in is “bent” at a 90-degree angle before it is pushed out the other side of the fan.
Although they function similarly, centrifugal cans are not the same as air blowers. The latter creates higher pressure ratios than a centrifugal fan can achieve.
This type of fan is typically attached to a system of ducts or tubes. This increases pressure, creating high-pressure airflow.
Centrifugal fans usually have lower flow rates, move lesser volumes of air, and have steadier flow than axial fans. They also require a high power input to operate.
Anytime you need to move air through ductwork, you will want to consider a centrifugal fan.
When ductwork is involved, the ducts increase pressure due to increased airflow resistance. To overcome this higher pressure, you need a fan that can produce high-pressure flow. You need a centrifugal fan.
This makes centrifugal fans ideal for air conditioning or drying systems. They are also great for caustic or corrosive environments. They’re extremely durable fans that work great for pollution filtration systems.
With enclosed parts and particulate reduction capabilities, these devices are difficult to damage and extremely durable.
Here are some of the key points you need to remember when choosing between the two types of industrial fans.

So how do you choose centrifugal fan vs axial fan? It all comes down to the application. Depending on what you need it to do, where it needs to work, and how much air it needs to move, you can pretty easily figure out which type of industrial fan is the most appropriate choice for you.
