The stationary air compressors are going to be fixed. They are usually bigger and provide greater power. However, the portable air compressor is smaller. But this kind of air compressors will come whenever you need them. Wherever you need them.

Getting the required power:- Talking about the power requirements keep two things in mind only. The tank size and air flow.

Air flow:- While buying an air compressor, check the specifications of it. Deliverable CFM and PSI especially. These two major factors determine the effectiveness of your air compressor.

Storage tanks:- Air compressors always consist of storage tanks. The more amount of air stored in your compressor, it will enhance the performance of your impact wrench.

Do your air tools are failing constantly to live up to your expectations? Do you have to buy a new impact wrench every month? Do they constantly fail to last until their warranty period? Well, this is an extremely common problem nowadays. As most of us over-pressurize their tools than written in the instructions. Using more pressure normally delivers more work efficiency. But, sometimes that can help you only to break your tool.

Here are some points that can help you with selecting the right air pressure for your impact wrench.

Reduce expensive tool repairing:

Using much air pressure constantly can become the main reason that your impact wrench keeps breaking a lot sooner than they do. You might be putting more pressure in order to get more work efficiency from your impact wrench. But, this is one of the main reasons for your impact wrench not living up to the warranty period even.

Maintain your tool’s efficiency:

Tools never break down in an instant in most of the cases. But it does, when it wears out over the time and reach a breakdown point. The seals and the other components become less efficient if the tool is getting worn down. This causes air leaks. As a result, your tool needs more air than it usually takes. So, use the right pressure always, to get a more efficient impact wrench.

Prevent dangerous accidents:

There is a safety manual guideline about the air pressure for a reason. Don’t use more air pressure until and unless you want to face a fatal accident. An accident that can damage your tool as well as hand you a hospital bill too.

Lower the fuel consumption:

Lower the level of fuel consumption. The more air pressure you use, the more fuel your tools consume. So, maintain your air pressure and save your fuel and money for an emergency.

 Can We Set The Torque On Impact Wrench?

Impact wrenches are made to help you with removing stubborn nuts and bolts. But, generating the perfect torque while using an impact wrench to tighten a nut in position is a bit hard thing to do. Although, some of the manufacturers add an air regulator in their wrenches. But, there are a lot of them who don’t. In these majority of the cases, you got only two options left to adjust the torque.

Regulate line pressure: To apply this process, turn on your compressor and let it run until it reaches the shut-off pressure itself. Then, attach your wrench to a compressor with an air hose. Once your wrench is connected to the air hose you can do it easily by adjusting the pressure regulator on the compressor.

Regulate tool pressure: To do so, you have to attach the tool air regulator to your impact wrench. Then, attach an air hose to the tool regulator and you can adjust the tool air regulator to generate the desired torque.

Some tips:-

  • Regulate tool pressure is a better option than regulating line pressure when you’re working in a shop or something. Because all the air tools in a shop depend on only one compressor sometimes. So, if you try to adjust the air pressure for an impact wrench, the other tools will also start working on the same air pressure.
  • This operation will not enhance the work efficiency of your impact wrench. However, they will only reduce the torque produced by your impact wrench.


  • Do not use more air pressure than the maximum air pressure recommended for any tool.
  • Always wear proper eye and hearing protection while working with these tools.

Is An Impact Wrench The Same As A Torque Wrench?

A torque wrench is not the same as an impact wrench. A torque wrench is used mainly to tighten nuts and bolts. Torque wrenches apply the same torque on different nuts and bolts. However, we can use impact wrenches as torque wrenches. There are different ways to control the air pressure and generate the desired torque with an impact wrench. But, applying the correct pressure with a torque wrench assures undamaged and perfectly tightened nuts and bolts.

Torque wrench: An air impact wrench is a favorable option used by most of the professional mechanics out there. But by not using a manual or air impact wrench properly you can end up damaging already installed parts. Air impact wrenches are a lot more powerful machines than you think.

Torque wrenches usually use a ball detent and a spring. These wrenches make a click as soon as it reaches the preset torque. On the other hand, air impact wrenches are not going to tell you if the torque is right. The applied torque in this kind of wrenches is indefinite too.

Risks of using an air impact wrench:-

  • Air impact wrenches pierce the turning thread.
  • As the air impact wrenches have no such options to help the user know if the pressure is right, it can damage the other parts too.
  • Ball pin in being drawn deeply in the housing.

When can you use the torque wrenches?

  • Use these wrenches while fitting the steering and suspension parts of a vehicle.
  • Use a torque wrench when it’s time to tighten the lug nuts too.
