Whether car painting is just a hobby or you do it as your profession, there’s always going to be one common issue that you may face-air compressors.
If you don’t own the proper air compressor for painting cars, then you can’t do it correctly or as efficiently. If you plan to operate more than one sprayer at a time, it’s important to take that into consideration when shopping for an air compressor.
The best air compressor for painting cars will offer consistent airflow and air pressure. As you may already know, pneumatic tools require a specific CFM and PSI to properly operate.
The CFM is how much airflow comes from the compressor and the PSI is how much pressure the compressor can handle. These two paired together to determine whether or not your pneumatic tool can operate to its full extent.
It’s recommended that you choose an air compressor that has a 3-5 HP motor with a CFM delivery between 4-6.5 CFM at 90 PSI. The compressor may have a lower HP and still deliver the recommended CFM.
Based on our testing, The California Air Tools 20020 air compressor is the best air compressor for car painting, because it meets the criteria above. It produces 5.30 CFM @ 90 PSI, which means you can get more out of it at 40 PSI. Additionally, it’s ultra-quiet and durable.

Unfortunately, we could not locate the exact Decibel rating of this machine, but user reviews boast of it being quieter than other comparable compressors.
Frequently Asked Questions
In this section, we will cover some of the most common and even uncommon questions that you may have regarding your air compressor choice.
Do Air Compressors Have A Power Rating?
An air compressor’s power rating is horsepower. Most non-industrial air compressors have a horsepower rating of between 1.5-6.5. However, some larger stationary air compressors can have a horsepower rating of up to 15.
It is important to know that gas-powered and electric air compressors have different horsepower ratings.
If you have an electric air compressor that is 5 HP, a gas or diesel-powered compressor would have to be at least 10 HP to do the same amount of work as the electric compressor.
Are Electric Air Compressors Better Than Gas-Powered Air Compressors?
Both types of compressors have their advantages. Gas-powered air compressors use gas to make power. These are great because you don’t need to utilize electricity to operate it as you would with an electric compressor.
Additionally, gas-powered compressors don’t have an automatic mechanism that powers up or shuts it down. Rather, they have a pilot unloader valve. This valve opens and closes depending on the pressure level within the tank. Essentially, this means that they will run continuously, which is ideal for when you need constant pressure.
The downfall to gas compressors is that they’re noisy and can’t be used indoors due to toxic fumes that may be emitted. This is where electric compressors beat gas compressors. They are generally quiet and can be used indoors.
Each type of compressor has its advantages, it’s just a matter of what you need the compressor for and where you’re going to be using it.
What Size Air Compressor Is Best For Air Tools?
When looking at air compressors for your pneumatic tools, you need to look at the CFM requirements. This stands for Cubic Feet Per Minute. You should look at the most powerful air tool that you plan to use and then compare it to the CFM output on the compressor.
If you plan to use more than one air tool at a time, combine the CFM ratings and to determine the power of the compressor. Once you have determined how much CFM your air tools are going to need, you will then have a better idea of how powerful your compressor should be.
How Do I Make Sure My Tank Is Safe?
A huge concern for homeowners using a compressor is whether or not their tank is safe. You can perform what’s called a “hydrostatic test” on the tank. This method pressurizes your tank well above normal pressure and it measures how much expansion there is when the tank is pressurized.
Metal will stretch a certain amount before it fails and the test and the test will show a reduced wall thickness. If the tank expands too much, this means that it’s weakened and you will need a new tank.
Why Is It Called “Airless” When It Uses Compressed Air?
Airless sprayers work by pumping paint from a gun at high pressures up to 3,000 PSI. The pain is pushed through a hose and out of a small hole at the tip of the gun.
The paint is drawn directly from a paint bucket or can. The paint compression system within the sprayer doesn’t come in contact with the paint and isn’t involved in the misting of the paint.
Do I Absolutely Have To Drain My Compressor After Each Use?
If your compressor uses a cast iron, steel, rolled steel, etc. cylinder, then yes, you do need to drain the compressor. The reason is that it helps ensure the lifespan of the seals, valves, and walls and keeps them from corroding. Additionally, your lines won’t fill with condensed air
If the compressor isn’t drained, water will pool at the bottom of the tank cylinder. It will eventually fail due to corroded seals and the water will eventually turn into oxidizing acid.
What Are The Top Air Compressor Brands?
Everybody has their own opinion as to what the top brands are. In our opinion and from what we have researched, we have found that California Air Tools, DeWalt, Craftsman, Stark, and Industrial Air are the top air compressor brands.
What Are The Different Types of Air Compressors?
There are three main types of air compressors which include reciprocating, rotary screw, and rotary centrifugal.
- Reciprocating: this is a positive displacement machine. It boosts air pressure by decreasing the volume. A reciprocating compressor can be used in both home and industrial settings. They also have low installation costs, are able to produce high pressure, and they’re easy to operate.
- Rotary Screw: Rotary screw compressors are also positive displacement units. They are one of the most popular choices when it comes to manufacturing industries. Each one has a 100% duty cycle and can operate 24/7.
- Rotary Centrifugal: These compressors don’t have cylinders, pistons, or valves. They have main bearings that need to be monitored. They can be single-stage or multi-stage units. They work by relying on energy transfer from the impeller to the air.
We hope that this guide helped you pick the right air compressor for your spray painting needs. As we mentioned before, the Industrial Air Compressor was our top pick due to its quietness and versatility.
Choosing an air compressor can be a daunting task if you don’t know what to look for, but it is our hope that our FAQ section assists with any questions you may have had.
It’s important to remember that you can’t just look at how many HP or gallons can be stored in the tank. You have to look at the specifications of your air tools and compare them to the ratings of the compressor you’re considering.
