What is the difference between air flow regulator and air pressure regulator?

Air Flow Regulators vs. Air Pressure Regulators: Choosing the Right One

If you are getting started using pneumatic tools/systems, you might be confused about air regulators, air flow regulators, and air pressure regulators. What is the difference between them?

Say an air flow regulator controls airflow, and an air pressure regulator can limit the pressure export.

Collectively called "air regulator." It has differences depending on the structure and environment. Please refer to the following description of the difference and application.

Air regulators can also be called "airflow valves" or " air regulator valves." Generally speaking, the structure of the air regulator valve is simple. It is usually used to control flow and is suitable for the end of the air pressure system. It is especially connected to air tools.

If you want to adjust the flow/ air pressure, you can only change it when using it. When stopping use, the number is the value of the air compressor source, not precisely using value. This always makes people misunderstand. The user will think the regulator is damaged. The air regulator valve isn't broken. When using, the correct value is the number, and it's time you can adjust the pressure flow. We need to notice that when the source of air pressure changes, the value of the regulator will change. It's suitable for the fixed air pressure source.

The other type is the "air pressure regulator," which is usually set on the front end of the air pressure system. It can limit the air pressure export. Of course, it can be used at the end of the system. But it will be a little heavier. But it can provide stable pressure. It can help the spraying user control the paint result more conveniently. Despite overpressure or less pressure, it all will have an effect.

The structure of the air regulator for spray guns is a diaphragm structure. Changing air pressure sources can stabilize export pressure and won't be affected. It's suitable for pressure or the head, such as a relay station shunt. To ensure the air pressure is the same on each air inline.

It's important to note that adjustments to airflow or pressure regulators should be made while the system is in use. When the system is inactive, the regulator will reflect the source air pressure value, not the actual working value. This can often lead to misunderstandings, with users thinking the regulator is malfunctioning when it is not. Always make adjustments while the air is flowing to ensure accurate readings.

Choosing the Right Air Regulator

Selecting the best air regulator depends on your specific needs and applications. Whether you need an air pressure regulator for stable output or an air flow regulator for controlling volume, choosing a product that fits your requirements and budget is important. For spray painting, a diaphragm-structured air pressure regulator is recommended for its ability to stabilize output pressure despite changes in source pressure.
