●  Extremely excellent power to weight ratio, wider torque range, suitable for multiple stations
●  Use of multi pole gearbox, uncompetitive reliability, constant speed and stable output
●  Gun design, in line with human mechanics, more portable
●  Equal torque output in forward and reverse directions
●  Low noise, non impact output torque
●  Accuracy ± 5%, repeatability ± 2% (correct air supply pressure and air volume are required)
