The magnetic suspension fan shown in the second picture adopts cutting - edge magnetic levitation technology. This technology uses magnetic force to suspend the rotor without any mechanical contact, which means there is almost no friction during operation. As a result, it has extremely low energy consumption, achieving remarkable energy - saving effects. Additionally, the absence of mechanical friction also makes it run with very low noise. Moreover, due to the greatly reduced wear and tear, its maintenance requirements are minimal. It is perfectly suited for scenarios that have strict demands for high efficiency, low energy consumption, and precise air - flow control, marking a significant advancement in fan technology.
