What Size Air Compressor Do I Need for an Impact Wrench?

The first thing to note down when you are looking for the correct air compressor size for an impact wrench is that it is dependent on the impact wrench’s size.

According to experts:

  • The average size of an air compressor you need to power an impact wrench is around 4 to 5 CFM @90 PSI for a ½-inch impact wrench.
  • For example, an impact wrench with a 1-inch drive requires an air compressor with 10 CFM @90 PSI.
  • On the other hand, a wrench with a ½” drive requires an air compressor with 4 CFM @90 PSI.
  • Whereas you will need an air compressor that delivers a 3 or 4 CFM @90 PSI for a ⅜-inch wrench.
  • Furthermore, some impact wrenches under $100 have a ½-inch drive. This is the most common among the home users, and you will need an air compressor that gives 4 to 5 CFM @90 PSI to run the same.

However, many factors determine the air compressor’s size you’ll need, such as type of task, impact wrench type, your power source, available space and when you plan to use it.

Besides, you can also calculate the air compressor’s size that you need to use an impact wrench and below, we will show you that:

Calculating the Required Air Compressor’s Tank Size:

It is important to know how much airflow your air compressor can produce so that you don’t overwork it. To figure this out, measure the size of the tank required for optimal performance and then choose one with enough capacity without being too bulky or heavy on transportation duty.

Keep in mind there are various sizes of air compressor tanks. Some are above 60 gallons. The rule here is simple; a bigger tank means your compressor will power the impact wrench for a longer time.

However, not many people know that an impact wrench doesn’t require a constant airflow like other power, so in most cases, it is advised to consider a smaller tank.

To find the appropriate tank size, multiply the impact wrench’s CP by 6. For example, if you have an impact wrench that gives 4CFM, the tank’s size will be:

  • 4CFM x 6 = 24- liters. Now that you know that a tank with a capacity of 24-litres will be required to power your wrench, you can opt for a slightly bigger tank.

To sum up, and in my personal opinion, 6-gallon air compressors with 4 CFM are the absolute minimum for impact wrench enthusiasts. Anything lower than that, and you might as well not even bother. The reason is simple: CFM, or cubic feet per minute, measures how much air the compressor can deliver. The higher the CFM, the more powerful the impact wrench will be.

And trust me, you need all the power you can get when you’re trying to loosen a stubborn nut or bolt. So if you’re serious about using an impact wrench, make sure you get an air compressor that can deliver at least 4 CFM. Otherwise, you’ll just be frustrating yourself.

Shopping Guide – Best Air Compressor for Impact Wrench

There are many factors that you need to consider before buying an air compressor. Some of these factors include the size of the tank, CFM rating, PSI rating, and noise level.

Size of the tank:

The size of the tank is one of the most important factors to consider when choosing an air compressor. If you have a small tank, it will not be able to store enough air to power your impact wrench for a long time. On the other hand, if you have a large tank, it will be difficult to move around.

CFM rating:

The CFM rating is another important factor to consider when choosing an air compressor. This rating tells you how much air the compressor can deliver per minute. A higher CFM rating means that the compressor can deliver more air per minute.

PSI rating:

The PSI rating is also an important factor to consider when choosing an air compressor. This rating tells you how much pressure the compressor can generate. A higher PSI rating means that the compressor can generate more pressure.

Noise level:

The noise level is also an important factor to consider when choosing an air compressor. If you have a noisy compressor, it will be difficult to use it in a quiet environment.

Now that you know the different factors to consider when choosing an air compressor, you can start looking for the best one for your needs. There are many air compressors on the market, so it is important to compare the features of each one.


The search is over! Now you know what is the best air compressors for impact wrenches are.

Frequently Asked Questions

How much PSI do I need for an Impact Wrench?

According to experts, 90 PSI is the least amount for a most air impact wrench to work adequately. However, we advise you to go with an air compressor with a higher shut-off pressure. Pressure loss during the working is also important, and you need to consider it when running an impact wrench. Thus you need to consider it when buying.

Will a Pancake Air compressor run an impact wrench?

The air compressor size you need to run an impact wrench depends on the wrench’s size. Generally speaking, you will need an air compressor that operates at 4-5 CFM and 90 PSI for a ½ inch impact wrench.

For example, an impact wrench that has a 1-inch drive will require a 10 CFM, whereas a ½-inch drive will need an air compressor with 5 CFM and 90 PSI.

How do Air compressors work?

How do air compressors work? It’s pretty simple. Air compressors take atmospheric air and force it under pressure into a tank. The air pressure builds until it reaches a point where the compressed air is released, providing a bit of kinetic energy that powers up various tools or just makes some noise.

Of course, when you’re using an air compressor, you’re not exactly looking to make a lot of noise. You’re usually trying to power some sort of tool, like a drill or a paint gun.

But the principle is the same – the potential energy created by the compressed air is converted into kinetic energy that you can use to do various work. Thanks, air compressor

Can a small Compressor run an Impact wrench?

This compressor operates with a 1HP motor and delivers 2 CFM with 90 PSI along with a determined tank pressure of 135 PSI will be enough to run most air impact wrenches.

What is the difference between CFM and SCFM?

This compressor operates with a 1HP motor and delivers 2 CFM with 90 PSI along with a determined tank pressure of 135 PSI will be enough to run most air impact wrenches.

The primary difference between CFM and SCFM is that CFM does not have any set pressure, volume, or temperature in which gas volume flow should be measured. Instead, CFM features different pressure and volume values as per the application.

On the other hand, SCFM has a determined set of conditions applicable to all calculations. SCFM features a standard volume, pressure, and temperature in which you can measure the gas pressure and flow rate.
Overall, these differences make CFM a more flexible and versatile measure of gas volume flow than SCFM. However, SCFM is a better metric for comparing gas flow rates across applications since it applies consistent standards to all calculations.
