How to Select the Best Air Compressor for Painting? (Buying Guide)

Before you finalize which air compressor you are getting for painting cars, there are a few things to consider to make sure the unit you get is worth spending every penny on. Undoubtedly, the tank capacity and size aren’t the only things that determine how good a compressor unit is.

As the unit you are about to get is primarily for painting purposes, you need to make sure that the device can easily deliver a steady stream of paint. Be sure to check for the following aspects when you select an air compressor.

Air Pressure

All the air compressor units mention PSI (pounds per square inch) value. It determines how much air force the pressure tank can deliver. Compared to HVLP paint sprayers, airless paint sprayers require more PSI.

Therefore, if you primarily use an airless sprayer, make sure the compressor unit is able to provide a decent PSI for painting cars.

However, if you mostly use HVLP sprayers, a compressor with low PSI will do the painting quite easily.

In most cases, people also use the compressor unit to power up other air tools as well. If you are about to do the same and pre-planned to use the air pressure for a secondary tool, be sure to check the PSI requirements of that tool.

It will make sure you will be able to do multiple tasks using the same compressor without compromising much regarding the performance. Most higher capacity air compressors will be more than enough for such tasks. If you are to buy a lower capacity budget-friendly unit, make sure you select the right one for your needs.

CFM – Cubic Feet Per Minute

This particular term indicates the amount of air a compressor unit delivers at a certain pressure. The numbers and figures might seem overwhelming to you. But, you need to give importance to this aspect to get the right equipment needed for the paint job.

Compared to other air tools, paint sprayers run continuously. Thus, they need relatively higher CFM ratings than other tools to be able to paint efficiently.

Make sure the CFM rating of the compressor unit meets the required CFM of the sprayer tool. Otherwise, your car will end up having paint flowing unevenly, or the paint will be splattered out of the nozzle when you press to spray on a car.

Again, an expensive and larger compressor unit will have a higher CFM rating. But, if you are settling for a small or medium unit, make sure the CFM rating is 30-32% higher in the compressor to paint effectively. Also, for using other air tools, be sure to consider their required ratings as well.

Tank Capacity

You need to pick an air compressor of the right tank size to be able to get consistent air pressure power to paint vehicles effectively. Compared to other light-duty air tools, painting sprayers deal with more demanding jobs. Thus, a smaller capacity compressor will not get a strong ground for the paintwork.

Professionals and experts recommend getting atleast 50-gallon air compressor for spray painting cars or higher to efficiently handle the task, especially if painting cars is something that you do regularly. Even if the larger tanks are a bit more expensive you you will save a lot of time, head ache and money in the long run as a good air compressor for spray painting cars as mentioned above can last up to 50 years.

Portability

First, you need to determine whether you will move the compressor unit or not.

Smaller air compressors are very easy to lift and move from place to place. As these come with a smaller capacity, it’s not your concern.

Larger capacity compressor units come with wheels or no wheels to serve specific purposes. Units with wheels are easier to move from one place to another. So, if you need to move the compressor frequently, be sure to get one that comes with wheels for easy mobility.

If you have fixed a place for a compressor in your garage or workshop, and there is no need to move the unit, you don’t need a wheeled compressor. These come with huge capacity, which is too difficult to move even on wheels. Therefore, larger units are for setting on a specific place or location.

Noise

As it’s about compressor machines, more or less all the air compressors produce noise. However, if noise is an issue that you cannot compromise with, be sure to get an air compressor that produces 70 dBA noise or less. It will keep the work environment a lot quieter.

If you want an air compressor for your home garage, a low noise unit will make sure the neighbors aren’t annoyed by the sound.

Oil or Oil-free

The pump or motor of air compressor units requires lubrication more or less. Oil-free units come pre-lubricated, and you don’t need to lubricate externally any further, thus, less hassle for maintenance.

Even though maintenance is a concern for pumps that require oil, these last much longer than oil-free ones, oil-based compressors are far less prone to wear and tear, which isn’t the case with oil-free units.

Installing Air Compressor Kit with a Spray Gun

Whether you plan to DIY paint your car or you are a professional, achieving a perfect finish is what matters. Even though you get the most expensive and powerful air compressor, if the entire setup isn’t good, most probably, the paint job will end up leaving ‘orange peel’ effects on the car.

Requirements

You will need an air compressor, filter or regulator, air hose, regulator, and obviously, the spray gun. Here I suggest using an HVLP spray gun.

Check the Compressor Unit

First, make sure the compressor unit can deliver the required PSI and CFM by spray gun. If you manage to set up the entire system, there will be no pressure drop or volume loss and imperfect coverage.

Get the Right Air Hose

The next step is to get an air hose of the right diameter and size. Pressure also drops if the hose is too long. Similarly, less air pressure is delivered if the hose is narrow.

Consider using a hose more than ¼ inch with an ID for your spray gun. As HVLP spray guns require larger volumes of air pressure, make sure you get one with more than 5/16 inch diameter. 8.5mm diameter hose can be a standard one to choose from.

Now, you need to make sure the air hose is of appropriate length. Get an air hose of 10m long. A longer hose will lose pressure, and a smaller hose can provide more air pressure than what is required.

Quick Connectors

If you attach the air hose to the gun, and there is no need to remove it frequently, it would be better not to use any quick disconnect fittings. Not using one will not affect the finish, but using unnecessary connectors can cause the pressure to drop.

But if your work requires you to use fittings, be sure to use less restrictive ones. The female portion of the connector should not be too small.

Get a Good Quality High Flow Regulator

Then, you will need an air regulator to make sure the air pressure is constant and smooth. Here again, don’t use a too restrictive regulator as it can cause an excessive pressure drop. Get a wall-mounted regulator; it delivers constant air pressure to the spray gun and minimizes unwanted pressure drops.

Connect the Gun and Start Spraying

Once you are done with the rest of the setups, attach the spray gun to the regulator, and give your car a nice-looking brand new look.

Operating and Maintaining Air Compressor for Painting Projects

A man painting a car

When you are all set for the paint job, know that there are two techniques to follow. Depending on your compressor configuration, specs, and your setup, you need to determine which one to go with.

Requirements

You will require 1 gallon of primer or base coat, 3 gallons of topcoat, and 2 to 3 gallons of clear coat. This is for a small or midsize vehicle. For a larger vehicle, get 1.5 gallons of primer, 4 gallons of topcoat, 3 to 4 gallons of clear coat.

Stripping or Sanding

First, you need to sand out the older clear top and base coats using a sander. For corners and crevices, you will need to use your hand for a better result. Sand the entire surface as smoothly and evenly as you can.

When it’s done, use a clean rag and paint thinner to wipe dust. Then let the thinner evaporate before proceeding further.

Priming

Mix the primer and thinners according to the instructed ratio. Now, mask off surfaces you don’t want to paint. Hold the paint gun six inches away from the car panel and spray in a sweeping side-to-side motion. Only hold the trigger when you move the gun.

The best is to do it from the roof down. Make sure you apply thin and even coats. You will need to give 2 to 3 coats to cover the panels. It takes about 10 minutes to apply. The primer will take 20 to 60 minutes to cure between coats. You need to smooth the powdery finish of the primer using 2000-grit wet and dry sandpaper.

Now, use a dampened rag and thinner to wipe down the cured surface. Don’t use too much thinner, or it will strip out the primer.

Painting

Here comes the main part. Mix your paint and thinner, maintaining the instructed ratios. Apply the same spraying technique as you did for primer. It will require 3 to 4 coats to finish. Be sure to let the coats dry in between them.

Before proceeding to the final coat, remove powdery effects using 2000 grit wet and dry sandpaper. Wipe off the residue using a clean rag. You need to do the same after applying the clear-coat lacquer as well.

Remove the masking tape before the clear coat dries. Then, let the coat cure according to the instructed time. Once it dries, see if there is any imperfection. Suppose you find any, sand off the area using 2000 grit sandpaper and respray following the same processes.

Technique to Follow for Smaller Compressor Tank

If you have a small air compressor tank, you need to frequently drain water to be able to avoid the condensation issue. Consider draining water from the tank after every 2 passes. Draining water from a smaller tank takes only a few minutes, this patience will buy you satisfactory results and even finish.

Consider using a dry cloth or dryer to wipe out all the water from the tank.

Frequently Asked Questions

What size air compressor do I need for painting cars?

The recommended size of an air compressor for painting cars using a sprayer is 50 gallons. As the spraying gun requires more PSI and CFM, smaller compressor units don’t meet the requirements.

However, 30 gallons or fewer compressor units can do the task if PSI and CFM requirements of the gun meet the compressor’s specs.

Can you paint a car with a 30-gallon air compressor?

Using a 30 gallon or less air compressor to paint cars is quite difficult if the PSI and CFM have a lower rating. A smaller tank will struggle to paint the entire car at once.

However, if you can adjust a few things and counter the pressure drop, only then it’s possible to paint even with lower PSI and CFM ratings. I have mentioned one technique to follow for smaller compressor units in the previous section.

How many CFM do you need to paint a car?

To be able to get a smooth and evenly finished paint job on your car panel, you will need an air compressor with 12 CFM, at least. It will ensure a steady output to make sure the pressure doesn’t drop and ruin the paintwork.

What PSI should I use to paint a car?

An HVLP (high volume, low pressure) sprayer gun can handle paint jobs on cars using 10 to 15 PSI without much hassle. There is no need for higher PSI to be able to do so. CFM is something that is more important and needs to be higher than PSI for painting.

Can you spray paint with a pancake compressor?

Most pancake compressor units have 6 to 7 gallons of tank capacity and come with much lower PSI and CFM. Thus, it would be tough to get a good paint job using a pancake compressor as far as painting is concerned.

How many layers of clear coat should I apply?

Applying 3 to 4 layers of clear coat will be more than enough when it’s about painting cars. You need to let each of these coats dry before attempting another layer. It takes roughly an hour to cure properly, including applying time.

Conclusion

In the end, if you ask me to recommend the best air compressor for painting cars, I would recommend you to go with the 2340L5-V 5hp 60 gallons Two-Stage Compressor. This particular compressor unit has a huge 60-gallon capacity with higher PSI. Also, the PSI and CFM ratings are more than enough for doing professional paint jobs.

If you are to buy a professional-grade air compressor for an automotive repair shop, this industrial-grade compressor will bring great value for your money.
