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

If you are getting started user of pneumatic tools/ system, you might have the confusions of air regulator, air flow regulator, and air pressure regulator. What is the difference between them?

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

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

Air regulator, it also can call "air flow valve" or " air regulator valve". Generally speaking, the structure of air regulator valve is simple. It is usually used to control flow and suitable for in the end of air pressure system. Especially connecting to air tools.

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

And the other type is "air pressure regulator", it is usually set on the front end of air pressure system. It can limit the air pressure export. Of course it can be used on 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 of overpressure or less pressure, it all will have an effect.

The structure of air regulator for spray gun 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 line.
