A pneumatic tool is hand-held equipment, which increases productivity, a built-in pneumatic motor, due to which the energy of compressed air is used. Pneumatic impact wrenches need to be as powerful as possible, which means they need to be heavy.
The impact wrench works on the same principle as a hammer the heavier the faster you unscrew and tighten the nut. The pneumatic wrench can loosen tight fasteners such as rusted bolts or lug nuts. They can deliver out more torque and have a very promising rotating speed per minute.

Guide: What Is An Air Impact Wrenches?
Factors to consider when buying an air impact wrench
Pneumatic tools are used in industries such as construction, engineering, metalworking, and mining, it is pneumatics for paint shops, painting furniture, and repair work. The pneumatic tool has several unique features, due to which it significantly outperforms its competitors, namely:
- Pneumatic wrenches, drills, screwdrivers, and grinders have more power and performance than electric tools.
- Air tools are safe tools in every way. This and the minimum risk of fire, and the practical elimination of injuries because the built-in mechanism is designed for large revolutions.
- It is much cheaper to use pneumatic tools than tools connected to the mains
The disadvantages of pneumatic tools include the additional cost of a compressor for air supply, as well as the time required to organize the workspace. But once you set up the work, all these “minuses” will quickly pay off due to all the advantages that pneumatic tools have.
An air impact wrench can remove all nuts and bolts within minutes. An air impact wrench is torquing equipment that both professionals and home hobbyists can use. So, if you are any of the two, read this guide below and understand the factors you must consider before buying a wrench.
Torque/Power
The power is the core element that makes an air impact wrench perform its job. In scientific terms, power is referred to as torque. Torque is the power that can change the movement of anything, in this case, bolts or nuts. When it comes to an air impact wrench, the higher the torque, the more power it will exert to fix any bolt or nut.
When you buy a wrench, you must be sure that your estimated torque requirement is correct. Torque is calculated in hundreds and every job has a different torque requirement. For instance, to remove a nut from a car’s wheel requires a torque of 140 ft-lbs while this might vary when you want to remove a nut from a truck’s engine. In that case, the maximum torque required is usually 500 ft-lbs.
The maximum torque can vary from the wrench to wrench. The Ingersoll Rand 2235TiMAX has a maximum torque of 930 ft-lbs while AirCat 1076XL has a torque of just 550 ft-lbs. Depending on your needs, you can choose the wrench with your required torque.
Rotations per Minute
An impact wrench works on rotation. It relies on this factor to loosen or tighten a nut or screw. It is always recommended to buy an impact wrench that has a high number of rotations per minute. A wrench with an RPM of 3,000 and above is perfect for all kinds of jobs.
A wrench with a low rotation per minute can prolong a project for no good reason. Always choose a wrench that priories the rotations per minute more than the torque and Impacts per minute. All the air impact wrenches reviewed above have a maximum RPM starting from 8,000 which is pretty awesome.
Blows per Minute (BPM)
Blows per Minute is also referred to as Impact per minute. The torque of your wrench and blows per minute should be well-balanced. In an ideal situation, similar to rotations per minute, blows per minute should be also high enough. This is because a wrench needs a lot of contacts to do its job properly.
If you are unable to pay for a pneumatic wrench with a high impact per minute, look for a wrench with a high torque and rotations per minute. If both these things are high, blows per minute are allowed to fall off.
The Air Compressor size
This is also a very important factor to consider before you plan out to buy an impact wrench. An air compressor sources power to the wrench. An air impact wrench is nothing without a good-sized air compressor. A shortage of airpower can even ruin the most amazing and expensive impact wrench.
To confirm that the impact wrench you are about to buy has a compressor that can meet all your needs, ask for the air consumption data measured in cubic feet. The minimum requirement of pressure needed for a wrench to work well is 90 psi. Air compression above this figure is considered perfect for your wrench.
Lightweight
Your air impact wrench must be lightweight. Who wants to work with a heavy wrench on a 9 to t job, anyway? A perfect air impact wrench is one that is compact and lightweight and doesn’t impose stress and fatigue on your hands and wrists.
A lightweight impact wrench gives you more mobility to you and makes operations very convenient. All the reviewed wrenches above are extremely lightweight and compact.
Brand
This is important. Always consider the brand before you buy a pneumatic wrench. With a good brand comes durability which is the essence of using this tool. All the brands reviewed above, Ingersoll Rand, AirCat, and NitroCat, are well-established brands with a great reputation. They are known for manufacturing top-class air impact wrenches at feasible prices.
