You will find many kinds of it at a local store and online also. If you are looking for the best air compressor for your nail gun then it can be burdensome for you. There are several terms involved for an air compressor which may seem a bit more technical for a common people but, it will help them to buy the best one if they knew the meaning of these terms.

What Size Air Compressor for Nail Gun?

An ordinary nail gun is an intermittent power tool that does not require a continuous supply of air. You just need bust of air to drive nails into the wood. So, all you need is a portable air compressor having at least 2 CFM ratings and a tank of capacity of 2 to 6 gallons.
Now the required specification do vary but according to the type of nailers you have and its use.

Things to look for in an air compressor

What are the things to look for when buying an air compressor for your pneumatic nail guns? Here are 3 important factors you should consider.

Tank capacity

The capacity of any air compressor’s tank depends on the work that you are going to do. If you require the nail gun to operate for a long period of time, it is only fair that you will require an air compressor having a large tank capacity.

Most of the air compressors that are designed for powering every pneumatic tool like the power nailers, already have tank capacities from 1 gallon to 8 gallons. Of course, there will be more air compressors available in the market having larger tank sizes. But if you are looking for portability and having ease-of-use, especially if you are going to be handling a nail gun, 1 to 6 gallons should be enough for you to do.

Having a larger tank capacity does have its own benefits. The idea is simple; air compressors with larger tank capacity would give you the advantage of using the air for a longer period of time. If the air compressor has a small tank capacity, it won’t be long before the air pressure drops. Before long, you would find yourself waiting for the motor to pump the air and refill the tank for another use.


CFM, it’s full form is Cubic Feet per Minute. Before you buy any air compressor for your work, you should make it a point to check the CFM besides the tank size as well. And putting that in plain words, CFM indicates the measure of the rate of flow of air in a given time.

It is important to choose an air compressor having a CFM which is a bit of higher than the required CFM for your tool. This makes sure that your tool will work more efficiently with your air compressor and so will avoid underperformance of your nail gun. If you want to find out the right CFM for your nail guns, all you have to do is multiply the required CFM of your nail gun with 1.5. The resulting value is the right CFM for the air compressor which is required for the respective tool.

Air nail guns are one of the power tools that require least CFM rating or values as compared to tools like impact wrench or spray painters. The finishing nailer and brad nailer are the type of nailer that can work with just 1 CFM while a more power-hungry nailer, for example framing nailer requires 2 CFM ratings to operate properly. Since a nail gun requires short bursts of air instead of continuous bursts of air, an air compressor with 2-4 CFM would be more than enough.

PSI (Pressure)

The term PSI stands for Pounds per Square Inch. PSI indicates the pressure of the air per square inch of the area. Nearly all the small air compressors, even the best air for home garage compressors from top brands offer required PSI to operate air nail guns. So you don’t have to worry too much about PSI and should focus only on CFM which is the key factor.

It goes without saying that having a large PSI for your air compressor also has its own benefit. Higher pressure means that you will have higher amount of air in the same volume of tank.

CFM and PSI, both go hand in hand. Ensuring that your air compressor compliments the PSI and the CFM values will be beneficial for the long run of your tool. It is also important that you get an air compressor having a larger PSI than required for your nail gun. A pro tip to find the right PSI for your tool would be to multiply the required PSI with 1.25.
