Basics and Benefits of Pneumatic Torque Wrench

Whenever it comes to precision fastening equipment, a pneumatic torque wrench is unrivaled. It’s a dependable tool develope for quick and secure attachment in regulate bolting scenarios.

It’s also strong enough to resist even the roughest job site circumstances, which is great for individuals in the oil and gas, mining, and power generation industries.

Look no further than this masterfully crafted wrench for a fastening tool with great precision and repeatability.

So, what’s the big deal about the pneumatic torque wrench? To begin, the wrench has an air-driven motor that enables steady high-speed revolutions and a constant torque output. Furthermore, the combination of an air motor and a planetary gearbox allows for much faster operation while maintaining safety.

Unlike a standar impact wrench, the pneumatic wrench is powered by continuous gearing, which reduces noise to practical nil and eliminates the need for dangerous hammering.

About Pneumatic Torque Wrench

Pneumatic Torque Wrenches, also known as Nutrunners, generate torque in a tool that continually rotates without the noise or vibration of Impact Wrenches by using very high-powered and high-speed air motors linked to a high-ratio planetary gearbox. They work in tandem with a Filter/Regulator/Lubricator (FRL) system, which regulates the amount of air pressure delivered to the tool.

The continuous gearing of a pneumatic wrench significantly reduces noise, and you do not have to cope with the incessant hammering of its standard impact wrench equivalent.

Nutrunners typically work in an air pressure range of 20-90 PSI. The amount of pressure employed, as with a Hydraulic Torque Wrench, will define the tool’s output.

An air motor has a force of only 15-30 Lbf/ft but spins at thousands of RPM. When passing through the gearbox, the speed is reduce but the power is increase, resulting in outputs ranging from hundreds to tens of thousands of foot-pounds, with speeds ranging from a fraction of an RPM to dozens of RPM.

Benefits of Pneumatic Torque Wrench

We recommend new tools, and if you’re thinking about adding some Pneumatic Torque Wrenches to your toolbox, here are a few of the important advantages that might just sway you to buy one for yourself!

  • Low vibration design decreases the possibility of injury and operator fatigue.
  • It’s so quiet!
  • The trigger is user-friendly and ergonomic, allowing for simple tightening and loosening.
  • For excellent accuracy, a high-ratio gearbox turns fast-moving air into a forceful, sluggish action.
  • Low friction gearbox that minimizes wear while increasing uptime.
  • Standard reaction arm that can be tailore to your preferences.

The pneumatic torque wrench is the ideal instrument for any application that requires fast and precise controlled fastening, as evidenced by the capabilities listed above.


Hydraulic and pneumatic torque wrenches both are terrific tools. The main concerns are the torque output require, the location of the tools, and if the task is high-cycle.

If you’re going to be working outside at a power plant, pipeline, or refinery, a hydraulic torque wrench is most certainly the ideal instrument for the job, especially if it involves heavy bolts. When working in a factory on high-cycle applications, pneumatic is likely to be the preferable option.

Overall, a pneumatic torque wrench will be a great tool in your toolkit. In applications that require fast, accurate bolting, an ideal tube cleaning tool will undoubtedly make your job easier by delivering repeatability.
