To get that near-perfect finishing on your spray painting project, you must choose the right equipment from among the numerous options out there. Read on to find out all you need to know about the air compressor products and choose one that is right for you. In this article, you will find out what an air compressor is, how an air compressor for spray painting works, the best air compressor products you can choose from, and more.

How does an air compressor for spray painting work?

An air compressor uses a motor for filling a steel tank with air. When more and more air gets pumped into the air tank, the air gets pushed together and compresses.

The pressure chamber inside the machine builds up. A larger tank allows more air and thus the compressor can manage more pressure. When you use this compressed air, you pump it out through its air hose and provide air pressure to the tools you are using.

When you use the air compressor to spray paint, the air is driven through the air hose and in your spray gun. This creates an airflow drawing paint in its path using low pressure. This becomes a spray paint and enables you to spray paint your surface, completing your paintwork.

When the air compressor stops working, you can turn it on again and build up the air pressure to power your tool.

What to look for in an air compressor for spray painting

When you set out to buy an air compressor for spray painting, you must look out for a few specific details. You have to consider some important measurements for spray painting, CFM or cubic feet per minute, weight, pressure, style, and tank size.

You do not require a lot of pressure for your painting process, however, you do need to ensure that you have a sufficiently high PSI that can ensure consistent delivery. A thirty-gallon air compressor would be appropriate for small projects such as spray painting your furniture.

If you plan to paint your car, a thirty-gallon air compressor will work for you to apply spray paint on one panel. You will then have to wait while the compressor recharges. You cannot spray paint several car panels in one go.  

There is a large variety of air compressors and they are not all the same. Based on whether you are working on your DIY paint jobs, a large project, or a professional paint project, you will have to make different choices.

  • Pressure

Two main kinds of spray guns use compressed air. These are commonly known as HVLP and LVLP. As evident by their names, neither needs high pressure to function.

An HVLP (high volume low pressure) spray gun atomizes the paint coating by using low air-cap pressure at high volumes of air. This generally uses a pressure range of about a fourth or less of what is used in conventional techniques. The reduced velocity of the sprayed paint makes it less probable that it will bounce back.

The softer spray of the HVLP method delivers a softer spray and this reduces wastage of your material. This method does require higher air volume in comparison to conventional sprayers for which you need a bigger air compressor.

An LVLP (low volume low pressure) spray gun is more suited for single-stage enamels, clear coats, and vehicle painting. This is because of the finely atomized spray that is super soft. An LVLP is excellent for details as it paints at a slower speed than an HVLP.

  • CFM rating

The CFM is the most important element to consider while selecting your air compressor. The cubic feet per minute or CFM rating is based on the air volume that the air compressor provides at the given PSI.

Your compressor’s CFM rating must be higher than the CFM requirements of the air spray gun. If this is not there you risk a drop in pressure and volume, both of which can lead to imperfect coverage. 

While the CFM works as a direct function of the air pressure quantity that the air compressor provides, it does not tell us about the air compressor’s run time. This can vary significantly. The run time is however correlated directly to the air compressor’s capacity.

  • Weight

The weight of an air compressor determines how portable it is. If your painting project is very big, you will have to move around with your spray gun. In this situation, you may find it difficult to move the heavy air compressor around from one location to another.

On the upside, a larger air compressor may be a good option as its run time will be longer. Because this is a personal consideration, you can consider your options before you make a decision.

  • Style

Air compressors are available in several different styles; pontoon compressors, pancake compressors, hot dog compressors, and others. Look at all the various options as they will decide various aspects of the product and influence your choice.

  • Tank size

Lastly, the tank size is quite important for spray painting. This is because for the spray gun to operate efficiently, it needs continuous airflow instead of an intermittent supply as provided by pneumatic tools. Therefore, the air compressor must have sufficient storage to keep the spray gun operating smoothly. 

What are the different types of air compressors for spray painting?

There are several different kinds of air compressors. The three most popular ones are pontoon compressors, pancake compressors, and hot dog compressors.

  • Pancake air compressors

Pancake air compressors get their name based on their shape. They have a steel tank that has a round, flat shape. Pancake air compressors are perfect for painting projects, nailers, airbrushing, and other smaller projects.

They are really great due to their stability, lightweight, and relatively smaller size. Pancake air compressors are not very strong thus they are not very suitable for high-volume projects.

  • Hot dog air compressors

Hot dog air compressors are also named after their shape. They have a somewhat bigger tank size and can work for bigger projects and larger paint jobs in comparison to the pancake air compressors.

On the upside, they have a longer run time and give higher max psi. However, because of their larger size, the hotdog air compressors are not as stable, lightweight, or portable.

  • Pontoon compressors

Pontoon compressors resemble a pontoon boat. They have a combination system with a series of several hot dog compressors.  

These workhorse air tools provide much higher max psi in comparison to the other kinds of air compressors. The high tank capacity means that they can handle large and lengthy paint projects and provide air pressure for a range of power tools.

While they can manage quite large air volumes, they are not very portable. You cannot haul them around your job site like the other models. They are not suitable for DIY projects.

Choosing the right air compressor for spray painting

Spray painting is an exciting, yet challenging project. You need to ensure that you do everything correctly so that your final coat has the perfect finishing you can be proud of. While choosing the air compressor is an important decision, it is not something you should worry about.

We will discuss several options and you will surely find the best air compressor to meet your needs for your painting project. There are options such as high-capacity air compressors, tanks with longer run times, oil-free compressors, and more. There is one that is right for everyone.

You will not have to worry about the air pressure when you use any of the air compressors on our list. These are all good products, and you just have to choose one based on what you want. If you want to start off with a small project, go with a simple pancake air compressor.
