"Micro Cooling Fan" use of water cooling, usually increases the humidity in the room, if necessary, can be used or desiccant dehumidifier to reduce humidity of the room. "Micro Cooling Fan" when not in use, the water tank should be clean long clean, room temperature air for some time, let the machine especially the screen section is completely dry and then put a plastic bag, to prepare for reuse. Compared with conventional ball bearings, oil bearing, magnetic bearing no mechanical contact with the rotor can run to a high speed, with mechanical wear small, low energy consumption, low noise, long life, no lubrication, no oil pollution, etc. especially suitable for high-speed, vacuum, clean, and other special environment. Maglev in fact only an auxiliary function, not form independent bearing, "Micro Cooling Fan" specific application forms have with other bearings.
