That’s typically the range I personally work in, Along with many others in the airbrush community.īut that’s not to say that, that PSI range is going to work for you. That being said, If I had to state a commonly used PSI range for that would work best for the majority of airbrush artists out there, then I would say:Ī good starting PSI range for most utilizing an airbrush is somewhere in the neighborhood of 15 PSI – 45 PSI. That is, in order to achieve an optimal spray pattern.īut the big takeaway here is that the consistency of the material to which you choose to spray through your airbrush is likely going to have the largest impact on the pressure required for you.

Meaning, the thicker the paint, the greater the air pressure you will require, and the thinner the paint, the less pressure you will require. This is because paint viscosity, and air pressure both feed off one another. Rather, the question should be phrased something more along the lines of: “What PSI should I be using based on the thickness of my paint, and the object being painted?”. You see, asking: “What PSI to use for an airbrush?” is only half of the overall question to which many should be asking. Simply speaking, required air pressure for an airbrush is not a specific set amount, commonly it depends heavily on multiple factors such as the airbrush type your using, the viscosity of the material to which you intend on spraying through the airbrush, the surface to which you intend on painting, and so forth… (More on these impacting factors later) But knowing the proper PSI to use is likely going to be different from one user to the next. When it comes to using an airbrush, air pressure (PSI) has a large part to play in the overall workings behind the airbrush.
