An air compressor a must-use tool for your nail gun. Here you may ask, “what size air compressor for nail gun?”
Size matters a lot in the effective use of your nail gun. So, you must know the accurate size of your air compressor.
This article will answer your question as well as help you to buy the proper air compressor.
What Size Air Compressor For Nail Gun?
The size of the air compressor necessary for nail guns change based on the kind of nail guns that are being utilized.
For example, when you’re nailing the frame, you’ll need a larger flow rate than when you’re nailing the finish.
To generalize, a nail gun that requires 0.5 to 4 CFM at 90 PSI can be easily operated with a compressor that has a capacity of 6 gallons.
Here is a chart for your fast calculation,
| Type of nail gun | CFM Requirements | Pressure | Min. Compressor Requirements |
|---|---|---|---|
| Finish Nailer | 0.5 to 1 CFM | 60 to 90 PSI | 2-Gallon Compressor Capable of 2.0 CFM at 90 PSI |
| Palm Nailer | 1 to 2 CFM | 70 to 90 PSI | 3-Gallon Compressor Capable of 3.0 CFM at 90 PSI |
| Roofing Nailer | 2.2 to 2.5 CFM | 90 PSI | 6 gallon Compressor Capable of 3.0 CFM at 90 PSI |
| Brad Nailer | 0.5 to 1 CFM | 60 to 90 PSI | 2-Gallon Compressor Capable of 2.0 CFM at 90 PSI |
| Framing Nailer | 2.5 CFM | 90 PSI | 8-Gallon Compressor Capable of 4.0 CFM at 90 PSI |
Things To Consider Before Choosing An Air Compressor For Nail Gun
Tank Capacity
The tank’s capacity is dependent on the work to be performed. If you will be using the nail gun for an extended amount of time, it is reasonable that you will need a large-tank air compressor.
The majority of air compressors meant to power pneumatic tools, such as power nailers, have tank capacity ranging from 1 to 8 gallons.
There will inevitably be air compressors on the market with higher tank capacities.
However, 1 to 6 gallons should suffice for mobility and ease of usage, particularly if you will be using a nail gun.
Having a larger tank capacity is advantageous. The concept is straightforward: a greater tank capacity would allow you to use the air for a longer period of time.
If the air compressor has a tiny tank capacity, the air pressure will drop rapidly. Prior to long, you would be forced to wait for the motor to pump air and refill the tank.
However, as stated previously, the size of the compressor would depend on the nature of the operation.
If you need the nail gun for standard household tasks, a lesser tank capacity will suffice, and vice versa.
CFM
Cubic Feet per Minute is the abbreviation for Cubic Feet per Minute.
Before purchasing an air compressor, you should also examine the CFM in addition to the tank size.
Technically, if your air compressor has a CFM rating of 5, it would blow a particular amount of air at a surface area of 5 square feet per minute.
In addition, CFM represents the rate of air flow during a specific time period.
Choose an air compressor with a CFM that is somewhat greater than the required CFM for your tool.
This ensures that your tool is compatible with your air compressor and prevents your nail gun from underperforming.
Multiply the needed CFM of your nail gun by 1.5 to determine the appropriate CFM for your nail gun.
The result is the correct CFM for the air compressor required for the relevant tool.
In comparison to products such as impact wrenches and spray painters, air nail guns are among the power tools that use the least CFM.
The finishing nailer and brad nailer can operate with only 1 CFM, however, the framing nailer requires 2 CFM to function correctly.
Since a nail gun requires short air bursts rather than continuous air bursts, an air compressor with 2 to 4 CFM would be sufficient.
PSI (Pressure)
PSI is an abbreviation for Pounds per Square Inch. PSI represents the air pressure per square inch of space.
Almost all compact air compressors from top brands have sufficient PSI to power air nail guns.
Therefore, you should be less concerned with PSI and more concerned with CFM, which is the crucial component.
Having a high PSI for your air compressor is without question advantageous. A higher pressure results in a greater amount of air in a tank of the same volume.
For instance, an air compressor with a 1-gallon tank and 150 PSI would hold the same volume of air as a 1.5-gallon tank at 100 PSI.
CFM and PSI are complementary. Ensuring that your air compressor matches the PSI and CFM numbers will benefit your tool in the long run.
It is also recommended that you acquire an air compressor with a higher PSI than your nail gun requires.
Multiplying the required PSI by 1.25 is an expert tip for determining the proper PSI for your tool.
HP
The Horsepower of the air compressor is denoted by HP. The horsepower rating of an air compressor reflects the entire motor power.
Simply said, it indicates the amount of work the air compressor is capable of performing in a particular amount of time.
For small portable air compressors, horsepower is of little importance.
When you select a compressor with sufficient CFM, PSI, and tank capacity, it will typically have the sufficient horsepower.
A 5 HP air compressor cannot perform the same amount of work as a 10 HP air compressor.
However, other elements, such as the CFM and PSI of the air compressor, also come into play.
In some cases, 5 HP and 10 HP air compressors can produce the same PSI at the same rate of 10 CFM.
In this instance, it is apparent that the 5 HP air compressor is more efficient than the 1 HP compressor, which is losing energy.
Along with the CFM and PSI of the tools, the appropriate HP must also be considered.
Thermal Safety
If your air compressor does not have a cooling system and you use it for an extended period of time, it is likely to overheat.
Overheating might cause long-term damage to the machine.
Consequently, with thermal protection, your unit will include an auto-off function that will turn the machine off when it becomes too hot.
Portability
A tiny air compressor will improve both your efficiency and usability.
It makes sense for a workshop or factory to have a large air compressor that can power many tools.
However, portability is more vital for builders, construction workers, and home renovation projects.
When an air compressor is overly huge and heavy, pneumatic instruments like nail guns become burdensome to use.
Additionally, the topic of storage is brought up.
Consequently, to prevent these concerns, ensure that you choose an air compressor that meets your portability requirements.
Noise Level
Some of this equipment is extremely noisy.
Initially, you may believe that this won’t matter much, especially if you just use the tool periodically for repairs or home improvement projects.
However, this might become extremely irritating after a few uses of the compressor.
FAQs about air compressor size for nail gun
What Size Air Compressor For A Brad Nail Gun?
Brad nailers don’t require much. Brad nails have a small head and are not particularly thick. So they require less air. Typically, brad nailers work at 0.5 to 1 CFM and require 60 to 90 PSI.
Your compressor should provide 2.0 CFM at 90 PSI and have a minimum 2-gallon tank capacity.
What Size Air Compressor For Framing Nail Gun?
Framing nailers are required to have a greater CFM rating than other nailers on this list. Typically, they require about 2.5 CFM at 90 PSI.
This indicates that a compressor capable of 4.0 CFM at 90 PSI will suffice. A 6- to 8-gallon tank is sufficient for use with a framing nailer.
Final Thoughts
Now you know the answer to the question, “what size air compressor for nail gun?” Numerous variables can effect the size of air compressor nail gun requires.
The most significant consideration is the compressor’s CFM and the equipment that will be used with it.
However, you’ll find that a 6- to 8-gallon compressor will suffice for the vast majority of nail guns on the market.
