Industrial fans are used for ventilation, cooling, fresh air supply, dust collection, and exhaust gas extraction in factories, industrial parks, buildings, and workshops... Commonly known for two types of industrial fans are axial and centrifugal fans.
Let's learn about 2 lines of industrial fans in this article. Helping you choose the right industrial fan.

Concept
A centrifugal fan is a fan with two different suction and blowing directions. There is usually one direction of air intake and one direction of airflow. Shaped like a snail or scallop.
Axial fans have a cylindrical shape, and the direction of suction and blowing is parallel to the axis of the fan. After the air is drawn in from one end, it will be blown out at the other end.
The same point
  • These two lines of industrial fans are both popular exhaust fans on the market. They can absorb dust, hot air, and moisture inside the space to the outside. To help the space become clean, and airy, limit dust.
  • Both are 2 fan lines with large capacity and large flow. Therefore, it is widely used in large industrial environments such as factories, factories, etc.
  • There are 2 fan lines, direct and indirect. The two types of direct and indirect fans are distinguished through their construction. Direct current has a motor directly attached to the impeller, whereas indirect flow has a motor attached indirectly through the belt and then to the impeller.
Differences
1. Different fan shapes: axial fans usually have round cylinders or square boxes depending on the location and installation purposes to choose the right fan line. In that gas, the centrifugal fan is shaped like a snail or an oyster.
2. Difference in blade structure: Axial fans usually have a much smaller number of blades than centrifugal fans. Thanks to their different wing configurations, they also have different specific applications.
3. Difference in input power: centrifugal fans often have extremely high input power, while axial fans have lower input power.
4. Different applications: centrifugal fans are often used to vacuum and filter dust thanks to their extremely strong suction, they are capable of thoroughly sucking exhaust gases and waste. On the contrary, axial fans are mainly used for ventilation and cooling or can be used for kitchen smoke extraction, welding fume extraction, etc. Not commonly used for chemical environments. Because the impeller is in the path of the exhaust airflow, it is easily exposed to dirt and easily corroded, reducing the efficiency of the fan.
5. Pressure difference
Centrifugal fans generally have much higher compression efficiency than axial fans. They can generate pressures up to 100,000 Pa or even higher. Meanwhile, axial fans only have an average pressure of 50 - 500 Pa.
Should use an axial fan or centrifugal fan
Many people initially do not know whether to choose a centrifugal fan or an axial fan. And quite confused about this issue. Then don't worry, below we will answer for you as follows:
To choose the right fan, you need to determine what the purpose of using the fan is. If you only use it for air circulation, you can choose an axial fan. If it is necessary to vacuum and filter dust in harsher environments such as wood dust, steel dust, chemical dust, etc., it must be treated before being discharged into the environment. You need to choose a centrifugal fan to get the best dust collection efficiency.
In addition, it is necessary to choose the pressure, flow, and size ... on the needs of users. To know exactly, you should choose a supplier for the fastest and most suitable advice.
