The PTS™ 72 series has been developed to take account of ergonomics, such as sound level, speed and weight. The low weight of the machine combined with the high speed and stall-torque (non-impact) drive makes it easy to work with high torques. The torque can be set easily by adjusting the air pressure against the supplied graph (torque/bar). Interchangeable square pins are available for easy and cost effective maintenance. Sound level 77 dB(A) under load. All models feature a soft start to make work easier. A wide variety of accessories is available, e.g. nose extensions, angular gear and built-in torque transducers for higher accuracy.
