Centrifugal fans and axial fans are two popular industrial fan lines today. They all have high applications for industrial parks, factories, or high-rise buildings. So should choose a centrifugal fan or an axial fan? To choose the right fan, see the information below. Hope you can choose the right centrifugal fan or axial fan for your project.
Similarities between centrifugal fan and axial fan
Same industrial exhaust fan
Centrifugal fans and axial fans are both industrial fans with 2 suction and blowing heads. The same is used for industrial parks, factories, factories, high-rise buildings …
There are 2 types of structures
These two fan lines have 2 main types of structure:
👉 Direct-drive fan: the motor structure is directly attached to the fan shaft.
👉 Indirect fan: the motor structure is attached to the fan shaft through belts, bearings, and bearings.
Both can be used for ventilation
With the mechanism of 1-way suction and 1-way blowing, these two fans can be used for ventilation and cooling in large spaces. With large capacity, stable operation, suitable for blowing wind, supplying fresh air to factories, industrial parks…
Both can be used to vacuum dust and exhaust gases
Together with strong suction, capable of sucking dust and exhaust gas from industrial zones. As the equipment of the dust collection system, the exhaust gas treatment system. Ensure the working space is free from pollution and dust. As a result, the working environment is clean, protecting the health of employees.

Use centrifugal or axial fans?
By comparing the similarities and differences between centrifugal fans and axial fans. Buyers have learned more or less about these two types of fans. However, to decide to choose an axial fan or centrifugal fan.
Here are some questions you need to answer:
❓ The size of the area to be cooled is large or small?
❓ Does the space need continuous cooling or cooling on demand?
❓ Is the operating environment in harsh conditions?
❓ Is fan noise an issue?
❓ What is the expected life cycle?
❓ Are our maintenance and repair important factors?
❓ Does the space need to use a ducting system?
Answering the above questions is a way to help shoppers choose the correct industrial exhaust fan for their needs. Hope the information in the article brings a lot of usefulness to readers.
