One of the most crucial parts of buying an air compressor is determining the right size compressor for your task. Not everyone buys an air compressor for the same purpose. Anyone who is buying an air compressor for painting purposes should know about what size air compressor for painting. If you’re one of them, then this post is for you!
We already discussed how an air compressor is important to make any painting job effortless. Easy application, smooth finishing & most importantly, long lasting persistence make this our favorite way of painting. Applying paint through air compressor sprayer is pretty common these days. Starting from painting a wall to paint on a canvas, this method is everywhere!
What Size Air Compressor For Painting
As we mentioned, there are actually many types of painting tasks you can do by using an air compressor. The paint type, the application process & the surface area are definitely not the same for all the tasks.
For example, you do not need to buy a full size air compressor for painting on art canvases. We have to use an air gun for such cases. These air guns do not need much high air volume or air pressure. So you do not have to spend that much while you can still do the job by buying the smaller air compressor for painting.
On the other hand, a full size air compressor is essential in case of heavy painting tasks. For example, industrial painting or even car painting requires a high end air compressor for continuous works. You will need the same for wall painting too!

Anyways, an air compressor should have specific air pressure & volume specification to meet your purpose. That is why we are breaking all the painting tasks down into several categories in order to help you make the most specific choice.
So let’s dig in—
Airbrush Air Compressor
An airbrush air compressor or airbrush compressor is one of the most important parts of an airbrush kit. This kit is necessary for precise painting like body painting or miniature sculpture painting. An airbrush compressor is pretty smaller than any other air compressors.
Usually, an airbrush compressor needs to have a range of 30-35 PSI air pressure with 0.5-1 CFM air volume for efficient operation. Otherwise, the airbrush gun will not run as per expectation. You can use a higher range air compressor to use an airbrush gun. But a smaller size compressor gives you more ease and comfort to move with the machine.
Although, your air compressor might need more air pressure & volume range depending on the task. Some particular airbrush painting jobs require more pressure and air volume to make the process efficient. Like for t-shirt painting or fabric painting, you will definitely need more PSI. As per our recommendation, you should set your compressor at 50-65 PSI for effective painting.
Air Compressor For Paint Sprayer
For any type of professional painting, a paint sprayer is what you use. Besides, you will surely need a good quality paint sprayer for large DIY projects like painting walls or your own car! Either way, you’ll need a high capacity air compressor.
To operate a paint sprayer, you will definitely need a higher tank capacity. As a rule of thumb, we would definitely recommend buying an air compressor with a minimum capacity of 30 gallons. To get a continuous shift, there’s no exception to that.
Unlike tank capacity, your air compressor doesn’t need much air pressure and air volume to operate a paint sprayer. You can work smoothly with an air compressor with an air pressure range as low as 1 CFM at 45 PSI. Although we would recommend to set your air compressor at 2 CFM at 90 PSI for the best output. Try to buy an air compressor with more horsepower engine, so that your machine gets a long-lasting lifetime.
