Ventiladores axiais vs centrífugos: as grandes diferenças que importam

Have you ever looked at a fan and noticed some have blades that resemble airplane propellers while others have curved blades more similar to hamster wheels? It is known as the axial and centrifugal fans. PC fans are crafted to function in specific styles to propel air. By knowing how they work we can understand why they are applicable in different scenarios. 

Therefore, in this text, we will mix both the good and the bad things of axial and centrifugal fans. We will look at their designs and cover what distinguishes each kind of fan. To help us understand the key differences between these two varieties of fans, we will be collaborating with HangYan, a revered company that creates industrial fans. Being aware of this information will aid you to get to know better which fan works best for either jobs. 

Axial and Centrifugal Fans: The Good And The Bad

Ventiladores axiais:

Axial fans suck air into the center of the fan and then blow it out in the same direction as the blades are rotating. That means they are great at moving a lot of air at low pressure. Axial fans are commonly used in cooling towers, HVAC, and sometimes even building ventilation as they are perfect for applications where low pressure is required. 

Good things about axial fans:

They effectively move plenty of air. 

They run quietly, which is a boon for noise-sensitive areas. 

They are relatively small so can be fitted into various areas. 

They are energy efficient, requiring less electricity.  

Bad things about axial fans:

They don’t excel when you need high pressure. 

As the pressure increases, their efficiency decreases, limiting their ability to function. 

This may limit their use in certain situations, as there is less design variation available with a blade. 

Ventiladores Centrífugos:

Centrifugal fans operate in a different fashion. They generate a closing force that drives air away from the center of the fan. This makes them extremely good at moving air with higher pressure. Centrifugal fans are commonly used in many applications found on industry processes, such as drying systems, boiler systems and air pollution control systems. 

So good things about centrifugal fans: 

They do well under intense pressure so are good for difficult roles. 

They can tailor the exact blade you need for the particular task. 

They can handle hot air, which is relevant in many industrial applications. 

Centrifugal fan disadvantages: 

In some environments, such as a library, this will not be appropriate. 

They usually consume more energy than axial fans, which may raise running costs. 

They generally have a bigger and denser structure than axial fãs, which makes them also more difficult to mount in restricted areas. 

Axial vs Centrifugal Design Comparison

Ventiladores axiais:

Compound fans are more sophisticated than axial fans. They also have fewer moving parts, which makes them easier to maintain. Axial fans are available in various sizes, ranging from tiny to huge. And they come with various blade shapes, straight, curved, even twisted designs. These are typically wall- or ceiling-mounted fans, and they feature a cylindrical body which encompasses the blades. 

Ventiladores Centrífugos: 

Centrifugal fans are more complex, with more moving parts. They also vary widely in size, though they can be larger and bulkier. Centrifugal fans feature variable blade types, for instance forward-curved, backward and radial options. As a result, they are designed as box-like structures that contain an inlet duct for air to come in as well as an outlet duct for air to go out, andare usually positioned on a base or stand. 

Pros and Cons of Each Fan

Advantages of Axial Fans They are with some great advantages. They can move air fast and silent, and are therefore well-suited for many uses. They are also more energy-efficient, so they cash flows savings on electricity. Moreover, their more simple design leads to a simpler care plan, leading to potentially lower maintenance costs. That said, axial fans do have some downsides. They lack the ability to maintain functionality under high pressure, do not offer great variants in terms of blade designs and thus can limit their scope in certain missions. 

Centrifugal fans, on the other hand, are more powerful and adaptable. Able to withstand high pressure, superheated air, and being ideal for harsh industrial applications, screw compressors also are highly versatile. They also provide such a range of blade draws, which allows them to be customized to a precise requirement. On the contrary, ventiladores centrífugos are noisier compared to axial fans which makes them less applicable in quiet environments. The also draw more energy to run, which can drive up cost, and the complexity of their design means they can come with more maintenance requirements. 

Main Differences Between Axial and Centrifugal Fans

The differences between an axial and a centrífugo fãs pode ser resumido da seguinte forma: 

Direction of flow: Airflow in axial fans is parallel to the shaft, whereas airflow in centrifugal fans is perpendicular to the shaft. 

Pressure handling: Axial fans are ideal in low pressure conditions, while centrifugal fans are better in high pressure scenarios. 

Blade designs: Axial fans have limited options for blade designs, while centrifugal fans have plenty of designs for customization. 

Size: Centrifugal fans are typically larger than axial fans, making them harder to fit into compact spaces. 

Sound: Axial fans are quieter; centrifugal fans are louder. 

Energy consumption: Axial fans consume less energy and are therefore more cost-efficient over time while centrifugal fans require higher energy demand. 

Which Fan Is Best for You? 

Consider the task you are hiring the proverbial fan for when determining what is the ideal fan for you. An axial fan is a good choice if you're looking for a fan that can move a lot of air easily and can fit into tight spots. But, If you want a fan to operate under high pressure and can be used on hot air, then a centrifugal fan might be a good choice. 

HangYan has several categories of fans, including axial fans and centrifugal fans. You can customize them according to your exact needs and requirement. HangYan fans use quality materials and clever technology to deliver energy-efficient, reliable and durable products. 

This tells you everything you need to know to compare axial and centrifugal fans, and make the right choice for your application. Whether it be an axial fan or centrifugal fan, HangYan is there for you to guide you to the best option that will meet and exceed your needs. You'll know the advantages and features of each type of fan, you will be wise enough to choose a better one.
