Buying Guide; How To Choose The Best Air Compressor For Impact Wrench

In the section,  we will look at some of the important things to consider before you purchase an air compressor for impact wrench. 



CFM stands for Cubic Feet per Minute.  This measures how much air the air compressor can move per minute.  This is what tells us how much air is expected out of the hose. 

One important thing to note  is that an impact wrench is an intermittent air tool. This basically means, it uses the area in short bursts. This means, unlike an air gun, you don’t need as much CFM as a continuous machine when it comes to an impact wrench. 

However, impact wrenches require certain amounts of air to drive bolts but if it’s more than the machine can supply, it will end up draining the tank. This also means that if the CFM isn’t not sufficient to keep the tank full, you will be required to take frequent breaks to allow it to catch up.

Unlike nail guns, impact wrenches don’t need nearly as much CFM as other tools; however, they require more than a nail gun.  

It is always advisable to purchase the highest number of CFM you can to supply you with enough air to complete any job.


Tank Size

The tank size of your air compressor for impact wrench is a very important factor to always consider. This is because, as the impact wrench works, the tank will lose air and as such, the pump will replace that air based on its CFM rate. 

That means,  if you use the air faster than your air compressor can replace it, you will need to take a break to let it recharge.  As a result,  it is always advisable to go in for a larger tank especially if you use your impact wrench a lot or the compressor is not very strong.


Other Features

The CFM and tank size are perhaps the most important things to look out when choosing an air compressor for impact wrenches. However, there are other important things to also consider.



If you desire to use your air compressor for other tools, some machines will allow you to easily adjust the PSI level available from the hose. This is a very important feature as you will be able to make adjustments through a regulator. You have to make sure the model you go in for has a durable regulator you can easily change.  



An impact is not a tool you can easily move around and as such,  if you plan on using your air compressor with other tools, you should consider the weight of the air compressor before purchasing it.



There is nothing more frustrating than an air compressor that keep sliding air while you are working with it. This is why it is always advised that you  check how the air compressor you intend on purchasing holds air and how it can stay pressurized overnight.  


Drain Valve

Having an air compressor with a good drain valve is very important.  The truth is, many people fail to consider the drain valve until after they’ve purchased the air compressor. 

It’s important to note that condensation can build up and chase with, a terrible to settle at the bottom of the tank and as such, if you have a good drain valve,  it will easily remove the water before it causes corrosion or rust. 




What size air compressor do I need for an impact wrench?

When purchasing a suitable air compressor, the tank size is another thing to consider.  It is always recommended that you go in for an area tank of at least 5 gallons for minor keys such as 4 inches. 

However, if you use an air tool regularly,  5 gallons cans of air will be more than sufficient. 


How many PSI does it take for an impact wrench?

It’s important to note that the size of the impact wrench is what determines the air pressure required to operate the air compressor. 

Most impact switches usually operate in the 90 to 100 psi  while others require higher air pressure than that.  


Which is better, air or electric impact wrench?

This will largely depend on the user’s preference as all these types of impact wrench have advantages and disadvantages.


Will a pancake air compressor run an impact wrench?

Yes. You can use a little air compressor with an impact wrench like the poster pancake type.
