1, the ball bearing: air gas ion for a long time for oxidation of ac fan bearing dust, dirt accumulation, can lead to dawdle bearing resistance increases, the fan speed gradually decreases.
2, oil bearing, oil bearing ac fan, mainly by friction between the stator and the coil rotation, and the oil bearings, with the use of fan, the work and time consumption, reduce gradually, the fan works, wind speed slower and slower.
