& nbsp; & nbsp; & nbsp; Air floating fan and magnetic levitation fan are currently the two most common types of blower products in the manufacturing industry. They have significant differences in different working fields, product structures, and usage aspects. Below, we will analyze their differences:

working principle

  & nbsp; & nbsp; & nbsp; Air Suspension Fan: The air suspension fan utilizes aerodynamic principles to support the fan rotor by forcibly introducing airflow and generating an air film, allowing it to operate suspended in the air.

  & nbsp; & nbsp; & nbsp; Magnetic levitation fan: The magnetic levitation fan uses electromagnetic force to suspend the rotor in a magnetic field, and controls the position and speed of the rotor through current, thereby reducing mechanical friction.

Design Structure

  & nbsp; & nbsp; & nbsp; Air suspension fan: The design structure is relatively simple, mainly composed of the fan rotor and the housing. The fan rotor is suspended by the support of the airflow, reducing mechanical contact and thus reducing friction and wear during operation.

  & nbsp; & nbsp; & nbsp; Magnetic levitation fan: The design structure is relatively complex, mainly composed of three parts: magnetic levitation bearings, electronic control device, and fan rotor. The magnetic levitation bearings use magnetic levitation technology, allowing the fan rotor to operate in a contactless state. The electronic control device is used to monitor and control the position and speed of the rotor.

Operating characteristics

  & nbsp; & nbsp; & nbsp; Air suspension fan: It has the characteristics of low friction, low noise, and low vibration, but the speed adjustment range is relatively narrow and the response speed is slow.

  & nbsp; & nbsp; & nbsp; Magnetic levitation fan: It has high stability and reliability, can reduce mechanical friction, avoid vibration and noise generated by traditional fan operation, has a wide range of adjustable speed, and fast response speed.

Noise control

  & nbsp; & nbsp; Air suspension fan: Through optimized design, the generation and propagation of noise have been reduced, making it suitable for scenarios that require lower noise and vibration.

  & nbsp; & nbsp; Magnetic levitation fan: adopting non-contact suspension technology, reducing mechanical friction and collision, with low noise level, suitable for environments with stricter noise requirements.

Applicable fields

  & nbsp; & nbsp; Air suspension fan: commonly used in air conditioning systems, ventilation equipment, and general industrial applications, with high cost but easy maintenance.

  & nbsp; & nbsp; Magnetic levitation fan: Due to its high stability and reliability, it has gradually been applied in fields that require precision control, such as medical equipment, semiconductor manufacturing, and precision instruments.

  & nbsp; & nbsp; When considering equipment using these two types of fans, the following factors are worth considering:

  & nbsp; & nbsp; Magnetic levitation fans may be more suitable for environments that require quietness and stability due to their sensitivity to noise and vibration.

  & nbsp; & nbsp; Considering maintenance and operational costs, air suspension fans may be more convenient and economical for daily maintenance due to their simple structure.

  & nbsp; & nbsp; For applications that require rapid response and wide adjustment of speed range, magnetic levitation fans have significant performance advantages.

  & nbsp; & nbsp; Overall, air suspension fans and magnetic levitation fans each have their unique advantages and applicable ranges. When making a choice, one should consider the actual application scenario, environmental requirements, and budget constraints comprehensively. The correct choice can not only improve industrial production efficiency, but also achieve energy conservation and emission reduction goals, promote sustainable development. Our air suspension fan developed by Smart has the advantages of high speed, low energy consumption, large air volume, low noise, etc., and can be customized according to different working conditions to make customer applications more practical.
