A pneumatic torque wrench is a torque wrench powered by a high-pressure gas pump. A torque multiplier with three or more swing gears is driven by one or two powerful pneumatic motors. The torque size is controlled by adjusting the gas pressure, and each tool is equipped with a dedicated air pressure first to control the torque chart and correction report in order to allow specific torque requirements. For further applications, pneumatic torque wrenches can be combined with torque sensors to produce more accurate torque. The gas source can be switched off manually or automatically using a suitable circuit system after obtaining the required torque.

The operation of the pneumatic torque wrench is quiet - below 85dB(A), absolutely shock-free, reducing damage to tools, sleeves and locks, both of which make the tool comfortable to operate, reduce fatigue, improve safety and torque up to 300,000N .m.
