What are the characteristics of axial flow fans?

The main features of axial flow fans include: large flow rate, small air pressure, small size, light weight, simple structure, high fan efficiency and wide working range. Specifically: Large flow rate and small air pressure: The axial flow fan can generate a larger air volume, but its air pressure is smaller than that of the centrifugal fan. Small size and light weight: The axial flow fan can be greatly reduced in volume, cover a small area, and is light in weight under the same flow rate. Simple structure: The structure of the axial flow fan is relatively simple, which helps save metal and processing time, and also means that maintenance may be relatively easy (although some point of view are mentioned that the air mechanism is complex, this may be not a common phenomenon for a specific type or design axial flow fan). High fan efficiency: After adjusting the rotation of the blade, the axial flow fan can work in the new optimal working area to maintain high efficiency. Wide working range: The efficient working area of ​​the axial flow fan is wider than that of the centrifugal blower, so its working range is relatively wide. In addition, the axial flow fan also has different characteristics according to the type of motor. For example, the AC axial flow fan driven by an AC motor has the characteristics of simple structure and low price; the DC axial flow fan driven by a DC motor has the characteristics of small size, light weight and high efficiency; while the EC axial flow fan driven by a permanent magnet motor has the characteristics of high efficiency, energy saving and environmental protection. 6 . These different types of axial flow fans are suitable for different application scenarios and requirements.
