Whether you’re an artist or a DIY enthusiast, airbrush painting can be an extremely rewarding and creative hobby as long as you have the right air compressor to power it. One of the most important elements is getting the correct size air compressor for airbrush in order to achieve optimal results.


But how do you know what size air compressor for airbrush best suits your painting needs? In this article, we will be discussing everything to find the right size air compressor for your airbrush. From learning exactly what requirements must be met all the way up to purchasing tips that could save time and money. So let’s get started!

What Size Air Compressor For Airbrush

What Size Air Compressor For Airbrush



For an airbrush, you’ll need an air compressor with a CFM rating of at least 4-6 and a PSI rating around 10-45. HP should be 1, and the tank size should be around 6 gallons or higher.

What Is An Airbrush?

An airbrush is a small, handheld air tool that uses compressed air to atomize paint and spray it onto a surface. It is powered by an external source of pressurized air (an air compressor) which provides the force needed to spray the paint. Airbrush painting allows you to create fine details like miniature painting, or large scale art with ease and precision.


Types of Airbrushes:

There are two types of airbrushes available on the market:


1- Single-Action Airbrush

2- Double-Action Airbrush


1- Single-Action Airbrush:

Single-action airbrushes are the most basic type, consisting of a simple trigger that allows you to control the flow of paint. They are great for beginners and can be used for various projects such as stenciling, shading and coloring details.


2- Double-Action Airbrush:

Double-action airbrushes offer more control than a single-action brush. The trigger on a double-action airbrush has two functions: pulling the trigger back controls the amount of paint released, while pushing down adjusts the airflow. This allows for more precise and detailed work such as creating gradient effects and fine lines.


7 Important Factors to Consider When Selecting an Air Compressor for Airbrush:

Factors to Consider When Selecting an Air Compressor for Airbrush


When selecting an air compressor for airbrush, there are several important factors to consider:


1. PSI Rate:

The pressure at which the air is expelled from the compressor is measured in pounds per square inch (PSI). A higher PSI will allow you to spray finer details and create more intricate designs.


2. Horsepower:

Horsepower (HP) is a measure of the compressor’s power and determines how quickly it can deliver air. A higher HP rating will allow you to spray faster and with more control.


3. Tank Size:

The size of the tank on your compressor determines how much air is stored and released when spraying. Smaller tanks are better suited for detailed work, while larger tanks provide more consistent airflow for large scale projects.


4. CFM Air Output:

Cubic feet per minute (CFM) measures the amount of air that passes through the compressor per minute. A higher CFM rating means more air delivered at any given time, making it easier to cover large surfaces quickly.


5. Flow Meter:

Some compressors feature an adjustable flow meter which allows you to control the amount of air that is released for precise results.


6. Duty Cycle:

The duty cycle rating tells you how long a compressor can run before it needs to be shut off and cooled down. Make sure to select a compressor with an adequate duty cycle for your projects.


7. Portability:

If you plan on taking your compressor from job to job, portability should be an important factor in your decision. Choose a model that is lightweight and easy to transport.


Factors in Detail:

Now let’s discuss these 7 factors one by one in detail.


PSI Requirement for Airbrush:

The PSI required to run an airbrush is usually between 10 and 45 PSI, depending on the type being used. Single-action airbrushes typically require lower pressure than double-action models, while gravity feed models need less pressure than siphon feed ones. Always check your airbrush manual for the exact requirements before selecting an air compressor.


CFM Requirement for Airbrush:

Cubic feet per minute (CFM) measures the amount of air passing through the compressor each minute and is also important when selecting an air compressor for airbrush. A higher CFM rating will allow you to cover more surface in less time, while a lower rating is better suited for detailed work. As a general rule of thumb, 1-3 CFM is best for single-action airbrushes and 4-6 CFM for double-action models.


Horsepower Requirement for Airbrush:

The horsepower (HP) of the motor will determine how quickly it can deliver air and should match the PSI requirements of your model. For example, if you are using a single-action brush that requires 15 PSI then you will want to look for a 1/8 HP or higher rated motor.


For double-action brushes, you will need a higher HP rating to deliver the required pressure. For example, a 0.3mm tip that needs 45 PSI would require at least 1/3 HP motor.


Tank Size Requirement for Airbrush:

The tank size of an air compressor is important because it determines how much air can be stored and released. Smaller tanks are best suited for detailed projects such as painting fine lines or shading, while larger tanks provide more consistent airflow for larger scale projects.


It’s important to select a tank size that meets your needs without being too large. Overly large tanks can increase the cost of the compressor and create unnecessary wear on the motor due to lower PSI levels.


Flow Meter Requirement for Airbrush:

A flow meter allows you to adjust the amount of air that is released when spraying, making it easier to achieve precise results on detailed projects. Most compressors come with adjustable flow meters or preset settings that can be adjusted accordingly.


Duty Cycle Requirement for Airbrush:

The duty cycle rating determines how long your compressor can run before needing to be shut off and cooled down. Compressors with high duty cycles are better suited for prolonged use, while those with lower ratings should only be used for short painting sessions.


Portability Requirement for Airbrush:

If you plan on taking your compressor from job to job, portability is an important factor to consider when selecting one. Choose a model that is lightweight and easy to transport without sacrificing power and performance.


Can I Use Small Air Compressor For Using Airbrush?

Yes you can, as long as the air compressor meets all of the requirements discussed above. But remember, bigger isn’t always better when it comes to airbrush compressors. Make sure to select a model that is ideally suited for your project needs without being overly large and costly. With the right size air compressor for airbrush and a little practice, you will soon be creating beautiful works of art with ease!
