Published Categorized as Reviews No Comments on 10 Best Air Compressors For Autopainting

Painting a car isn’t as easy as painting a wall or a piece of wood. Of course, you can’t exactly swipe acrylic paint over a car with a paintbrush, nor can you simply use spray paint from a can.

Autopainting (the term for painting a car or vehicle) requires a lot more than a spray paint can or paintbrush.

Luckily for you, we’ve got you covered. We have found the 10 best air compressors for autopainting for avid DIYers and expert auto body repairers alike.

We’ve also compiled a useful buyer’s guide to help you understand the type of air compressor you should buy.

Buyer’s Guide

What To Consider When Looking For An Air Compressor For Autopainting

The way air compressors work is by pressurizing air to produce a steady, even stream of paint to paint a car.

Air compressors are also used for small DIY projects and crafts, as well as pumping tires due to the amount of pressurized air they produce.

Here are the key factors to consider when looking for an air compressor for autopainting.

Tank Size

The size of the tank will determine the type of project an air compressor is suitable for. For a car, opt for the largest tanks with a capacity over 10 gallons. Smaller tanks are better suited for painting details and accents on a car.

Air Pressure

The air pressure (measured in PSI – pounds per square inch) indicates the strength of the air compressor in terms of airflow.

Keep in mind that airless paint sprayers require air compressors with higher PSI figures that HVLP paint sprayers, which require air compressors with a low PSI.


If you work in a large garage or workshop, or if you’re likely to need to move your air compressor from one location to another, you must consider the portability of the product.

Luckily, most air compressors come with handles and wheels, which makes it far easier to pull a heavy air compressor around.

Some industrial air compressors can weigh hundreds of pounds, which can lead to injury and damage to the unit if mishandled incorrectly.


The CFM (cubic feet per minute) figure indicates how much product the air compressor can produce depending on the airflow pressure.

Paint sprayers require high CFM levels to ensure they produce an even amount of paint to a surface.

So, if the compressor’s CFM levels are lower than the paint sprayer allows, then the paint will come out patchy and uneven.

Problems With Air Compressors

Air compressors come with several common problems which need to be addressed. Here are some of the problems with air compressors and how to fix them!


If you’re experiencing problems with low-pressure air, it’s most likely due to the length of the hose. Longer hoses will reduce the pressure of the airflow, so the best cure is to shorten the length of your hose.

However, if you have a large air compressor with a high PSI and you’re still experiencing low-pressure problems, there might be an issue with leaking connectors or the regulator.


If you see bubbles coming out of the paint sprayer, this indicates a problem with the CFM (cubic feet per minute).

The CFM figure shows how much product can be delivered depending on the pressure. Bubbles indicate a leakage, which can be identified and fixed by yourself. This leakage usually comes from the regulator or connectors.

Uneven Finish

Air compressors are meant to produce a high pressurized air flow to provide an even finish of paint, so when the finish is uneven, this can be down to three issues (not with the air compressor!).

Either you are new to using an air compressor for autopainting, you didn’t prep the surface properly, or your technique isn’t right.

It all comes down to practice. You need to clean the surface vigorously to ensure there are no textures on the car that will create weird blotches and patches.


Dripping usually occurs when there is trapped water in the line. Air compressors should come with a moisture trap to prevent water traps, so ensure that this is dry.

Dripping isn’t a bad thing, and can be cured by simply wiping the moisture trap dry with a cloth. This usually occurs in humid areas.

Frequently Asked Questions

What size air compressor do I need to paint a car?

The general rule of thumb with an air compressor for painting a car is to opt for the largest figures when it comes to capacity, CFM, and air pressure.

50-gallon tanks are probably the ideal size for painting a car, but a 20-gallon tank will also suffice for smaller cars.

High CFM ratings will ensure that the paint will cover the car evenly, so we recommend two-stage compressors with a CFM figure of around 20.

As for the air pressure, look for a minimum PSI rating of 90 PSI. The horsepower will indicate how powerful the motor is, so always go for the top figures of this.

How many CFM do I need for auto painting?

Air compressors require a higher CFM figure than other air tools to ensure an even finish. A small CFM figure will result in splattering and patches on the surface of the vehicle.

We recommend looking for an air compressor with a CFM figure of around 20, as well as a paint sprayer that will accommodate this.

Can you paint a car with a 20 gallon air compressor?

While the recommended capacity of an air compressor tank for painting a car is around 50 gallons, a 20-gallon air compressor can also paint a car. These tanks are better suited for smaller cars, but they will suffice for large cars, too.

The only issue is that 20-gallon tanks will probably need re-filling for larger cars.

Can you paint a car with a 6 gallon air compressor?

It’s possible to paint a car with any size air compressor, but a 6-gallon air compressor will simply need frequent re-filling. However, a 6-gallon air compressor is ideal for painting details and accents.

So, if you’re just wanting to paint the door of the car, then a 6-gallon air compressor will be the ideal size!
