How To Select The Best Air Compressor For Impact Wrench



The more air pressure the air compressors can produce, the more powerful it will be. And people always calculate air pressure through two factors:

  • CFM ( cubic feet per minute): these factors mention the mass of air flowing per minute.
  • PSI (pounds per square inch): this unit will denote the air pressure.

The best air compressor for impact wrench has to be the most suitable number of these two factors. And depends on the different sizes of the impact wrench, we can find out what is the most suitable one for each of them.

There is the fact that the bigger your impact wrench is, the more air it will need. And here are the best CFM and PSI for each:

¼ inch impact wrench

It is the smallest size of impact wrench, and it means that you don’t need much air pressure to run. So, the best air compressor for impact wrench ¼ is the one that can provide 1- 1/5 CFM. Of course, you can select the one with a bigger CFM without worrying about your wrench, but it is not necessary.

3/8 inch impact wrench

For a 3/8 inch impact wrench, you will need more air pressure. In particular, you need to double air pressure to run the 3/8 inch impact wrench. In our experience, you should better choose the one that can provide 3-3/5 CFM. You can also operate your wrench with a 2.5 CFM air compressor, but it will reduce the tool’s lifespan.

½ inch impact wrench

½ inch impact wrench is one of the most popular ones on the market right now. It is in the average number in size. And in our experience, the best air compressor for impact wrench ½ inch is the one with 3.5-5 CFM and 90 PSI of air pressure. You should at least select the air compressor with 4 CFM, and 5 CFM is the best option even if it is a little expensive.

Tank size

The tank size is also one of the most crucial factors you should pay attention to when looking for the best air compressor for an impact wrench. It will directly impact your work performance. And it is very annoying if you have to stop the work all the time and wait for the tank to refill.

So, if you own an impact wrench that is less than ½ inch, we suggest you should select at least 5 gallons air tank. If you are not a professional who has to use the wrench, 5 gallons is the best option for you.

It would help if you considered investing in more than 20 gallons of air compressor for bigger sizes of impact wrenches. It will ensure you a long working time with no interruption.

Other factors

Technically, there are three things you need to check before purchasing the air compressor: PSI, CFM, and tank size. However, there are still some other factors that will define if your air compressor is the best air compressor for impact wrench or not. And here they are:

Portability: you buy this air compressor for your impact wrench, which means that it is always on the move around your house, garage, or workshop. So, it would be best if you did not ignore the portability. And the one with the wheels and handles is the best option for you in this case.

Durability: of course, you don’t want to replace your air compressor after a few times of use. And that is why you should check the origin, material, warranty policy carefully to make the best decision.


Q: Would Porter cable work for blowing out PLASTIC water lines in winterizing a home? What size are the connecting air fittings? 1/4?

A: If you’re talking about your sprinkler lines, then yes (assuming 3/4″ tracks). As to the connector, it depends on your back-flow device.

Q: Due to the small tank, does Makita regularly cycle running a 1/2 inch impact wrench?

A: We run a 1/2 inch impact pretty regularly. It doesn’t cycle that much. It has a tough time with a cut off tool or angle grinder.


When you have to work with a heavy-duty task, we suggest that you pay more money to invest in the best quality product. Because your working environment is very harsh, and you always require your tools to work in high intensity and capacity. And it will waste more money than your expectations at the beginning.

So, when looking for the best air compressor for an impact wrench, you need to check the product reviews and ask the seller for as much information as possible.
