Similarities and differences between magnetic suspension centrifugal fans and air suspension centrifugal fans

There are no air suspension fans; this refers to the bearing part

Air bearings have a lower load-carrying capacity. Air bearings are cheaper than magnetic levitation bearings.

It refers to the differences among bearings: one is an air-lubricated bearing, and the other is a magnetic levitation bearing

It’s hard to say for sure; I still think that air-suspended centrifugal fans are currently more popular, as they have a small size and require less space； Simple structure, easy installation, straightforward maintenance, low failure rate, and so on~~ With further development of magnetic levitation, its application prospects may become even broader~~

What is the difference between magnetic suspension centrifugal fans and air suspension centrifugal fans? Have you used any of them?

On the surface, it can be understood that the design principles of the bearing housings for these two types of fans are different: one uses electromagnetic suspension technology, while the other uses pneumatic suspension technology. However, the overall approach is similar – to reduce energy loss at the bearings in order to enable fans to operate at high speeds with high airflow rates.

#Reply quickly here #1: The difference between the two lies in the type of bearings used; as the name implies, magnetic levitation uses magnetic levitation bearings, while air suspension uses air suspension bearings. What they have in common is that both types of suspension blowers use high-speed direct-drive motors, variable-frequency speed control for adjusting air volume, and contactless bearing technology; they do not require a lubrication system, thus causing no secondary pollution to the environment. They offer advantages such as high efficiency, low noise, no vibration, and a wide range of adjustable air volumes. 2. However, due to the special air conditions in China, air suspension bearings experience a higher failure rate when operating in such an environment; therefore, it is recommended to use durable magnetic suspension blowers. Let’s talk about magnetic levitation here. Companies abroad that are engaged in the research, development, and manufacturing of magnetic levitation bearings include MECOS in Switzerland, REVOLVE in Canada, SEVNZ in Germany, and TURBORMAX in South Korea. At present, magnetic levitation fans produced by SEVNZ in Germany and products from TURBORMAX in South Korea are quite common in the international environmental protection market, holding a high market share; therefore, they should be the first choice when using such technologies. Although the initial investment in such equipment is currently high, the higher economic efficiency of magnetic suspension single-stage high-speed centrifugal blowers can be achieved when taking into account the savings in civil engineering costs related to the foundation and blower room construction during the installation phase, as well as reduced electricity consumption and maintenance costs during operation. Considering the overall life-cycle cost of the project, these blowers represent the main development direction for aerating blowers in the environmental protection industry in the future.
