Or, what is the best air compressor for paint sprayer?) resolved. Here in this guide, I’m going to talk about all the nitty-gritty of air compressors. So, let’s dive in.

What is Air Compressor and How It Works?

From inflating tires, kiddie pools to unclogging the sink at your home, an air compressor can come in handy anytime. But if we talk only about professional requirements, then we must say an air compressor is a truly essential tool for regular mechanical work.

Whether you are looking to power a paint spray, a nail gun, or drive some pneumatic devices, an air compressor is a tool you need on all these occasions. If you have ever got confused thinking about how does an air compressor work, let us explain it to you here!

An air compressor forces air inside a container by pressurizing it. Now when needed, the air is forced out of the tank through an opening while maintaining the pressure. You can think of it as similar to an open balloon; now, in the case of an air compressor, you can control the air pressure and use the energy.

Air compressors come with an engine that converts electrical energy into kinetic energy. Just like a combustion engine, air compressors use a crankshaft, valve, piston, and a connecting rod along with the head; the pressurized air powers various tools like paint sprayers, sanders, and wrenches.

Depending on the working principle, there are various types of air compressors available in the market. Mainly there are two methods that air compressors use to achieve air compression. One is known as positive displacement, and the other method is dynamic displacement.

So, these are the basics of how does an air compressor work. Now before moving forward to find out what size air compressor is needed for spray painting a car or what is the best air compressor for automotive painting, let’s first check out what is an air compressor used for in automotive work.

What is an Air Compressor Used for in a Car?

If you are an avid automotive DIYer, then an air compressor is one of the essential tools that you should have in your garage. Starting from pressure washing to spray painting, an air compressor can come in handy on many occasions.

Are you still wondering, what all can you do with an air compressor? Here we have listed a few basic applications that an air compressor has for your car. Let’s have a look:

Spray Painting

This is one of the most crucial reasons why you need an air compressor. If your car requires a little touching up paint with a spray gun, then a top-rated air compressor for spray painting cars is what you need.

Seal off the area you are going to paint so that the things nearby remain protected from the paint. You must mask off the windows and other parts of your car on which you don’t want to get paint. Try to use a respirator for your own safety.

Then set the compressor with the right pressure so that it can draw the paint out of the gun. You can test-spray on cardboard before the paint actually comes out in a fine mist.

Pressure Washing

You can attach your air compressor with a high-pressure water spray gun and use it as a pressure washer. To use an air compressor with your pressure washer firstly:

  • Turn on the air compressor and allow it to build the required pressure.
  • Connect one end of your garden hose to a faucet that is outside of your garage.
  • Once you are done with that, connect the other end of the hose with the water line connection available on your pressure washer attachment.
  • Plug the air hose directly for the air compressor in the airline connector.
  • As you are done, your air compressor will surely make your pressure washing hurdle simpler. Moreover, you can use your air compressor and a water spray gun to pressure wash your car.

Inflating Tires

You can use your air compressor to inflate the flat tires of your car. It’s a simple step by step process that you need to follow to inflate the tires. Firstly, learn about the optimum pressure for your vehicle’s tire. Now, if you were driving the car before this, make sure you offer enough time to cool down the tires.

Once the tire you want to inflate cools down, adjust the valve and after that:

  • Turn the air compressor on.
  • Attach the air hose with the compressor.
  • Make sure you attach the quick coupler at the end. The fastener available will help to push air in the valve stem.
  • Keep a tab on the air pressure monitoring gauge.
  • Once the pressure reaches the required PSI disconnect the hose. Now put the nozzle back on the tire valve.

Air Blow Gun

Air blow gun is extremely useful when it comes to cleaning your car’s interior. The car’s interior is one of the most complicated places when it comes to dusting. You can use your air compressor by connecting an Air blow gun with it and use the tool to dry clean the car interior.

Air Sanders

Air sanders are essential when it comes to painting your car. You can achieve that polished and shiny finish only if you proceed with your sanding job properly before applying the actual paint. However, if you have got an air compressor that can operate at a pressure of around 90PSI, you can easily connect it with an air orbital sander.

Now you know exactly what is an air compressor used for in automotive work after checking out the large array of applications it has. Here, let’s take a moment to concentrate on the main purpose of this article (What size air compressor is needed for spray painting cars?). So, let’s scroll through and learn about the recommended air compressor size for spray painting.

What is a Good Size Air Compressor for Spray Painting Cars?

While setting up a home automotive shop, some of the most common questions that come up in our mind are “What size air compressor do I need for spray painting a car?” or “What is the minimum size air compressor for painting a car?”.

Are you having a similar short of a query? Well, here in this section, we are going to discuss specifically about the air compressor sizes and air compressor requirements for spray painting.

To get optimal performance while spray painting your car or truck, you need to get an air compressor with a tank capacity of around 50 to 60 gallons with a 3HP to 6HP compressor. Ensure that it produces enough CFM, which can run your spray gun. You should ensure that your air compressor for the paint sprayer has a CFM ranging from 14 CFM to 18 CFM at 90PSI.

Air compressors with a smaller tank may be able to get your job done. But if you talk about professional-quality finishing for your paint job, a small tank may not work that good. A small air compressor does not have enough air volume to paint your entire car. Hence, your spray gun will struggle, so the air compressor. As a result, there will be uneven paint spitting, and ultimately an uneven paint will not look good on your car.

Apart from that, if you have a smaller air compressor tank, you might have issues with the condensation of the paint. A smaller tank will get warm inside and form moisture for constantly being up and running.

If you don’t have space for a full-size air compressor to store inside your garage, you may consider checking out a turbine-style paint gun kit. These self-contained spray gun kits come with in-built air compressors but don’t have an air reservoir with them. And you can easily store them right under your workbench.

Also, if you compare an air compressor and a turbine-style paint gun kit, both the tools fall under a similar price range. Hence, the equipment will cost you as much as the air compressor costs. However, apart from spray painting, an air compressor has a handful of applications. You can use it to run several power tools. Therefore, if we talk about value for the money, then an air compressor is always a better option.

Important Things to Consider When Buying an Air Compressor:

If you are new in the automotive painting field, it won’t be super easy to choose the right air compressor you need to spray paint your vehicles. There are many factors that you must have to pay attention while choosing the best air compressor for spray painting cars or pickup trucks.

What air compressor do I need for spray painting? If this is your question, then you should know that from the air compressor sizes to its CFM, PSI ratings and lastly, the HP rating are the things that you will have to check out while buying an air compressor.

Are you wondering what is an air compressor CFM, or PSI or HP? Well, here I have got answers to all your queries. Please have a look at this list of considerations on how to choose an air compressor for spray painting cars and learn about all the crucial factors. Let’s check out:

What Size Air Compressor is Needed for Spray Painting?

Your air compressor size has a crucial role to play when it comes to spray painting your car. Don’t go with an air compressor that has a tank too small. Smaller tanks result in uneven paint flow. So, consider buying an air compressor that has a tank with a capacity of at least 30 gallon.

Anything smaller than a 30 gallon air compressor will contradict the paint flow. Alongside that, you have to stop your work more frequently, resulting in your painting job taking a much longer time.

If you have a coupe or sedan and are thinking of DIY spray painting, consider getting an air compressor with a capacity of around 30 to 60 gallons. If you are looking to paint an SUV or a van, then you need to get an air compressor that has a capacity of around 60 to 80 gallons.

Are you looking to buy an air compressor with an optimal capacity that allows you to spray paint different vehicles? Then I will suggest going for an air compressor with a tank size of 60 gallons or more.

What CFM is Required for Spray Painting Cars?

The CFM indicates the amount of air an air compressor can provide at a specific pressure. The abbreviation CFM stands for cubic feet per minute. It would be best if you bought an air compressor with the right CFM to spray paint your car. Generally, paint guns require a higher CFM rating to operate compared to other air tools. If you already have a spray gun, you may know that it can operate from 3 to 12 CFM.

Now coming to the question; how much CFM do I need for spray painting?

If you have ever tried spray painting before, you may be aware of the fact that the CFM output of the air compressor is essential to get optimal performance. Most of the paint guns require a lot of air to operate. Therefore, you need to select your air compressor depending on the automotive paint gun you are going to use for spray painting.

The air compressor needs to have a higher CFM than your paint gun. I will suggest you choose an air compressor with a CFM value between 14 CFM to 18 CFM based on my experience.

How Much PSI Do You Need to Paint a Car?

Apart from the size and CFM, it’s important to take PSI into consideration when it’s about buying an air compressor for spray painting. So, if you are looking for an answer to how much air pressure do you need to paint a car, here we have got the answer for you.

PSI is the unit to measure the pressure rating of your air compressor. It’s a myth that you need to crank the air pressure really high to get an even coat while spray painting your car. In fact, if you are at the beginner stage, you should try your hands on a relatively high volume and low-pressure spray painter that does not require higher PSI to run.

As far as my personal experience is concerned, I use around 10 to 15 PSI when I’m working on the base coat of my vehicle. I will suggest you go for that PSI range as well since this has always worked for me.

On the contrary, you should increase the PSI a bit when painting the clear coat. So, when working on the clear coat, keep the PSI rating around 20 to 25 PSI to ensure an even result.

How Much Horsepower Does Your Air Compressor Have?

Horsepower (HP) measures the amount of work the air compressor can do for you. The horsepower rating of your air compressor is crucial to know what exactly your air compressor can do and how well it can perform. For example, a compressor with a 5HP motor can’t perform even close to what a 10HP motor compressor can do for you.

Generally, the air compressors we use for spray painting come with a horsepower rating of between 1.5HP to 6.5HP. If you are looking to use an air compressor that operates from standard electric power outlets, you should look for a machine that has a 2HP or a lesser power motor.

The horsepower ratings change depending on the type of air compressor you are using. To do the same job with gas or diesel-powered air compressor that a 5HP electric air compressor can do, your gas-powered compressor needs to have a 10HP motor.

The reason behind this lack of efficiency is simple to understand. A compressor engine that runs on gas or diesel generates the power through combustion inside the engine, whereas an electric motor draws the power from a completely external source.
