Regulators & Filters

The Key to Precision Painting

Regulators and filters are essential accessories in an airbrush system, installed between the compressor and the airbrush. Their purpose is to ensure a clean and stable airflow, which directly impacts the quality of your paint job. Without them, airbrushing can be frustrating, and the results far from what you expect. In this category, you'll find devices that help you avoid common problems like water "spitting" or unstable pressure, which can ruin hours of work on your model.

What is a Pressure Regulator For?

A regulator, often equipped with a pressure gauge, allows you to precisely set and maintain a constant working air pressure. Compressors generate higher and often unstable pressure that is not suitable for direct use in painting. With a regulator, you can adjust the pressure for a specific task—lower values (e.g., below 1 bar / 15 PSI) are ideal for painting fine lines and details, while higher pressures are better for applying primer or varnish to larger surfaces. Stable pressure is the foundation for repeatable and predictable results, regardless of the type of paint used.

Air Filters – Why Are They So Important?

The second essential component is the filter, also known as a water trap or a water/oil separator. During air compression in the compressor's tank, water vapor naturally condenses, and sometimes oil particles can also be present. If these contaminants get into the airbrush, they will be sprayed out along with the paint onto your work surface, causing unsightly specks and runs. The filter effectively traps water and oil, ensuring that only clean, dry air reaches your model. Many regulator models feature an integrated filter, providing a convenient and compact solution for every modeler.
