Before we start the review, let me first explain the proper size of the air compressor that you need for your impact wrench.

What size air compressor for impact wrench?

It all depends on the size of your impact wrench. The average size of an impact wrench is 1/2″. This means that you need an air compressor that can deliver at least 3-5 CFM at 90 PSI to power the impact wrench properly.

Buying guide for air compressor for impact wrench

Most air compressors are quite expensive, so before you buy one, do your research. That’s why we’ve put together this comprehensive guide to help you find the best air compressor for air impact wrench for your needs and budget.

Here are some things to keep in mind when shopping for an air compressor or an impact wrench:

The size of the tank required an air compressor for the impact wrench.

One of the most critical factors which most people ignore is the size of the tank. It’s imperative to choose an air compressor with the right sized tank for your needs.

You’re wrong if you plan to use an impact wrench with a small 3-gallon air compressor. A small air compressor can’t provide the required power and will overheat quickly.

For using an air impact wrench, you need a minimum of a 6-gallon tank. But for best results, choose an air compressor with a 10 – 20 gallon tank.

Size and portability

Air compressors come in various sizes, from small, portable units to large, industrial-sized machines. What size is best it all depends on your needs.

If you plan on using your air compressor for impact wrench around the home or in garage, a small unit will suffice. Because portable air compressors are small and lightweight, they’re easy to move around.

On the other hand, if you need an air compressor for industry or commercial use, you’ll need a larger, more powerful unit.

Oil-free or lubricated

Oil-free air compressors are low maintenance and don’t require lubricating Oil. This makes them ideal for home use.

On the other hand, Lubricated air compressors require regular maintenance and need to be lubricated with Oil.

However, they’re more powerful and have a longer lifespan than oil-free compressors. So, if you need an air compressor for heavy-duty use, choose a lubricated model.


Air compressors are built to last, but some models are more durable than others. One way to gauge a compressor’s durability is to check the warranty.

A longer warranty usually means the manufacturer has more faith in their product. If you need a durable air compressor that can withstand heavy use, choose a compressor that includes cast iron construction and thermal overload protection.


After reading our detailed product reviews and buying guide, we hope you’ll be able to find the best air compressor for the impact wrench that meets your needs and budget. Keep in mind the different factors we discussed, and you’ll be sure to find a great air compressor that will serve you well for years to come.
