Air Compressor Buying Guide
Among many types of air compressors in the market, you should choose according to the air tool you wish to use. There are some factors you should consider while buying an air compressor. Following is a guide about factors to consider when choosing the best air compressor for painting cars, homes and furniture. This guide will make it easier for you to choose the best air compressor.
Motor
The efficiency of an air compressor mostly depends on its motor. If the motor is not sufficient or it does not have great horsepower, then the compressor won’t be very productive. That’s why, before buying an air compressor ensure it sports an engine with considerable force esteem.
If you are looking for a good enough compressors, then you could buy a compressor with a 1.6 horsepower motor. But if your budget is high and you are looking for something more than good, then you should buy a compressor with a 3.0 horsepower motor. 1.6 horsepower is enough for painting homes and furniture. For painting cars you need at least a 2 horsepower motor.
Pressure
Air pressure in an air compressor is an important thing to watch out for. The air pressure in an air compressor is measured by PSI (pounds per square inch). 90PSI is the least number for most compressors to work properly. But you definitely need to go over 100 PSI to work without any hassle. If you don’t want to spend much on the compressor, then 125 PSI is the number you should choose.
You can paint your car, house or furniture using 125 PSI. It will work just fine. But it is suggested that you should use at least 135 PSI while painting your car. After all, the higher the PSI the better work you can do.
CFM
CFM means cubic feet per minute. The capacity of air compressed by an air compressor in a minute is counted as CFM. CFM is a major thing to think about, before buying a compressor. For those who do paint jobs with air compressors, CFM is most important. If the CFM isn’t correct, the whole paint job may get hampered.
At first, you have to know how to calculate the required CFM of your air tool. You can get your required CFM by multiplying your tool’s needed CFM by 1.2. If your tools required CFM is 5.6, then multiply it by 1.2. So 5.6×1.2 = 6.72.
PSI vs CFM
A machine’s performance perfection always lies in each machine’s tools individually. So to have a wonderful service, one needs to know about all the measurements and key functions subsequently. Such an occurrence is put on light about the air compressor is PSI VS CFM. Though both of the operations indicate the ability of the air compressor, unlikely they are not the same. You might get confused over these two acronyms which need to be crystal cleared before graving.
Here are the differences between PSI and CFM measurements.
PSI | CFM |
PSI Stands for Pounds per Square Inch | CFM stands for Cubic Feet per Minute. |
Basically it defines How many pounds of pressure are utilized in an inch of area. | This measurement refers to the amount of air that is gained at a given pressure. |
It is the indicator of the output of the force for the compressor. | CFM represents the airflow,the more airflow it gives,the more applications are applied for. |
90 pounds per square inch is optimum measurement, but differs for larger applications and so on | Air compressors with higher CFM ensures required airflow and better performance. |
What is paint compressor?
A paint compressor is a type of spray gun that uses compressed pressure to paint. In this case, an air-pressurized spray gun is filled with liquid paints and when the trigger is pushed, this liquid paint mixes with compressed air and released as a spray.
Air compressor for painting-
One of the most popular ways to paint is to paint with an air compressor. In this way, an air-pressurized gun is used. When you pull the trigger, the liquid paint of the spray gun chamber will mix up with compressed and the paint will come out.
Air compressor for paint sprayer
To choose a suitable air compressor for paint sprayer, you need to consider 3 factors:
- CFM: CFM stands for Cubic Feet per Minute which is the volume of air produced by the air paint compressor. First, check the CFM requirement of your paint sprayer. You will need to check the CFM of your air compressor and buy the one that has higher CFM than your paint sprayer to be in a safe side. Another important issue here is the PSI rating. PSI stands for Pounds Square Inch which determines how much of force the air compressor will be able to deliver.
- Pressure: Check if your paint sprayer uses HVLP (High Volume Low Pressure) or LVLP (Low Volume low pressure). With these in mind, choose the air compressor that suites your paint sprayer. You should also check out the HP (Horsepower) rating of your spray paint compressor to know if the air compressor can maintain the needed pressure and flow.
- Tank Size: There are so many sizes of tanks depending on your work purpose, ranging from 1 gallon to 60 gallons. However, larger air tanks are often advised because with that, you can paint for a longer period.
Air compressor requirements for spray painting
For spray painting, you will need to consider these three things: CFM, Pressure and Tank size. The higher the CFM from your paint sprayers’ CFM, more opportunity to get maximum out of your paint sprayer. Secondly, your air compressors pressure should be on per with your paint sprayers’ requirements on whether it uses HVLP or LVLP. Lastly, depending on how long you are going to use the air sprayer or how much do you need to paint in a single session. Additionally, look out for the PSI and HP of the air compressor for more precision.
What is the smallest air compressor for painting
Usually an air compressor comes with a 30-gallon tank. You still can paint the whole car with this, but it will definitely take a lot of time because of the lack of size as it will take longer to fill up. Plus you also should consider the CFM and PSI of the air compressor if a small compressor can provide these. So, in this case, the safest take on the smallest air compressor should be 55 to 60 gallons with a decent CFM that suites your spray gun and can provide a formidable pressure for longer period.
Air Compressor Size For Painting:
Here’s a table for air compressor size for painting and their benefits.
Purpose | Gallon in Digit | Reasons | Benefits |
Cars | 50 | To avoid uneven and incomplete painting. | No worries for overspray |

Furniture | 20 | It needs a balance gallon digit to make sure the work is not messed up. | It provides even spraying experience. |
Paint sprayer | 20-30 | It requires 12 CFM to spray. A 20-30 Gallon air compressor provides the expected CFM. | Provides thorough spray. |
Framing crew | 6 | It provides powerful performance. | No intensity for power. |
How to size an air receiver tank?
Air receiver tank sizing is an uncomplicated and straightforward procedure. The rule is taking the appropriate tool with the highest CFM@psi and then multiplying the CFM by 1.25/1.5. Lastly, it requires assembling to the nearest gallon size.
How much CFM is my air compressor?
To test the air compressor CFM by own, you need to follow some steps as below.
Step #1 :
Note the gallon size of the air compressor, which is over the wall of the tank. Now get the Cubic feet, dividing the gallon size by 7.48. This value denotes the airflow in Cubic feet.
Step #2 :
For further testing, note the time of releasing the air and, after that, fill the tank again. The refilling time is most important, and another thing is to pay attention to the gauge when it kicks in and kicks out. Note these two times and subtract the values.
If the air compressor kicks in at 50 psi and kicks out at 75 psi, the difference is 25 psi.
Step #3 :
Following the next step, the difference value is divided by 14.7, and the value is the atmospheric pressure, which was added in the time of refilling.
Step #4 :
Now multiply the pressure value from step three with the air volume in cubic feet gotten from step 1. This value resembles the cubic feet at a certain time it took to refill (step 2)
Step #5 :
Finally, to have your CFM or cubic feet per minute, divide the value of step four by 60.
And in the end, it is your machine’s ability parameter or CFM value.
How an air compressor fails
Important note:
There are a lot of ways an air compressor can fail, and some of the switches they use can make arcs or sparks even under normal conditions.
Even if you use it every day, and even if you buy from a “trusted” brand, you should always unplug a compressor when you’re done so working it doesn’t start running when you aren’t around.
The failure rates California model aren’t much worse than other brands, as far as we could tell in our research. (5% one-star reviews is, as sad as it may be, a pretty low rate of failure compared to the major brands.)

What is compressor paint gun?
A compressor paint gun is an air-pressurized spray gun that uses compressed air, mixed up with liquid paint in the chamber to generate paint spray for painting a certain portion. You can use the nozzle that comes with the paint gun to adjust the width of the paint radius.
Spray paint compressor function
In a spray paint compressor, there are 3 parts: a nozzle, air compressor and a paint basin. You take your desired paint in the paint basin. Based on the use, you can use any kind of thinner, like Acetone to make the paint lighter. After pressing the trigger of the spray gun, the paint will mix up with the compressed air, coming from the air compressor and paint will come out from the nozzle as a fine spray. Based on use and the object that needs to be painted, the nozzle can be adjusted, like full cone, hollow cone or flat stream.
How to Setup Your Air Compressor Kit with a Spray Gun?
Step #1 :
Unpack your spray gun and clean the oil. This oil is for avoiding any corrosion that is used for its protection for packaging. Then next, take the air nozzle, remove it and flush thinner into it. Flush it until it is clean.
Step #2 :
To clean the cup, take warm soapy water and fill it to the halfway. Fasten the warm water to the gun and shake well for cleaning the cup and the syphoned tube.
Step #3 :
Clean the spray gun with thinner or alcohol to clean any remaining junk.
Step #4 :
Take the tank based on your demanded size and clean it with thinner. Dry it up and then add the paint.
Step #5 :
You need to connect your air compressors hose with the spray gun. Take the male air hose coupling, connect it with the spray guns air connector, and adjust the air pressure with respect to the hose length. Pull on the ring on the safety pressure-relief valve of the tank to make sure it operates freely. Close the air supply valve after that and tighten the tank lid clamps.
Step #6 :
Open the main air supply and observe the regulator air gauge. If it shows any pressure, then reduce the pressures to zero.
How to Paint a Car Using an Air Compressor?
