1, little vibration. Although the rotor after precision machining, has become a State of equilibrium. But still using high precision dynamic balancing equipment for balance. So the fan operation is almost vibration-free.

2, high precision, high rigidity gear, not only extending fan life, also decreases the noise efficiently.

3, fans of this series with Japan or Germany imported bearing, import Korea or Taiwan rubber bands, so that product quality is more reliable.
