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

If you are getting started user of pneumatic tools/systems, you might have confusion about air regulators, air flow regulators, and air pressure regulators. What is the difference between them?


Simply say air flow regulator controls air flow, and an air pressure regulator can limit the pressure export.

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

Air regulators also can call "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. Especially connecting to air tools.


If you want to adjust the flow/ air pressure, you only can adjust it when using. When stopping use, the number is the value of the air compressor source not exactly using value. This always makes people misunderstand. The user will think the regulator is damaged. In fact, the air regulator valve isn't broken. The correct value is the number when using, and it's time you can adjust the pressure flow. 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.

And 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 the service of 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. It can stable export pressure and won't be affected by changing sources of air pressure. It's suitable for pressure shunt or the source, such as relay station shunt. To ensure the pressure is the same on each air inline.
