Outer rotor time 
 Green Island has been a strong wind ventilator product series specification is complete, and ventilation fans in the many outstanding products, all-metal series can be described as one of the most dazzling star, it is the first ventilation fans with external rotor technology products. External rotor motor performance, stability, inertia, smooth operation, wear, long life, manufacturing technology and the conditions are very high. External Rotor Motor marks the successful use of ventilation fans into a new technology era. All-metal series of ventilation fans at the same time with the wind wheel design, the same amount of wind speed greater; body slim, good looks; fire performance is strong; every product performance testing through the computer balance. Performance, with the incomparable advantage of as a replacement for the technology.
