Pneumatic torque wrenches are pneumatic torque tools that use compressed air as a power source to continuously output stable torque to tighten or remove bolts. Pneumatic torque wrenches usually have a digital display and torque adjustment function. By setting a torque, the air torque wrench will output torque to drive the nut and bolt to tighten. An air powered torque wrench can work quickly, precisely and consistently. Even in harsh environments, an air operated torque wrench enables safe, fast and easy bolt tightening.

The application of air driven torque wrench is extremely wide. From industrial production to daily life, air torque multiplier can be seen everywhere. Its application areas mainly include mining, rail maintenance, chassis maintenance, power generation turbine bolts, tower section bolts, turbine casing bolts, pipeline flanges, valves, pressure vessels, etc.
