  • NPT Size: 3/8 Inch
  • Weight: 27.52 Ounces

Review

The PneumaticPlus SAU320-N03G Compressed Air Filter Regulator will provide you an effective pressure control and air filtration. This is why I chose it as the best air compressor regulator filter.

This is not only an air pressure regulator but also a filter that will remove harmful debris as small as 10 microns. There are multiple drain and bowl options for you to match your need.

The SAU320-N03G is compatible with an NPT size of 3/8 inch as I have mentioned in the specifications above. But there are a few more filter regulators you can get from PneumaticPlus that have different specifications.

For example, the SAU420T-N04G-MEP and the SAU420-N04G-MEP are almost the same but the first one has a T-handle. This is the only difference between these two. Both have ½ inch NPT size.

If you want a filter regulator for higher flow and smaller debris size, you can get the SAW400-N04BG. You can get the SAU400A-N04G – Dual Air System if you want to have both 3/8 inch and ½ inch NPT size.

Buying Guide for the Best Air Regulator for Compressor

It is a bit tricky to find the best air compressor filter regulator. But if you follow my instructions you can find the right air regulator for your air compressor. There are a few features you have to keep in mind about that. These are

The NPT Size

This is the size of the inlet and the outlet of the regulator. Both inlet and outer are connected to your compressor. There are some regulators that have universal NPT size and they will fit any air compressor.

On the other hand, some regulators have fixed NPT size for particular air compressors’ NPT. You have to match this size with your air compressor to get the right regulator for your compressor.

Operating Pressure Level

The operating pressure level will let you set the maximum pressure to a particular level. This has to match with your air compressor too.

If the air compressor provides a high pressure that the regulator cannot withstand on the inlet, the regulator will get damaged. So always get a regulator that has a higher operating pressure level than your air compressor.

Type of The Regulator

Some regulators are only for regulating air pressure and some are for filtering the air too. If you only need the regulator you can get the one that has no filter. But if you want a regulator with an air filter, you can also find this in my list above.

Extra Accessories

No matter how well the regulator is built, it will eventually leak a little air. To avoid this, you can use thread sealants. If you want, you can get a set of air regulator and thread sealant. That way you don’t have to buy the sealant separately and you can save some money.

Frequently Asked Questions

Do I need a regulator on my air compressor?

Some air compressors require regulator and some don’t. The ones that require a filter regulator or air pressure regulator usually come with a built-in regulator. But the built-in regulator gets damaged over time. In this situation, you need to get an air pressure regulator separately for your compressor.

How does an air compressor regulator work?

There is a set screw that controls the airflow through the tank. A spring is connected to the screw shaft. The air pressure is set by the pressure of this spring.

There is a diaphragm connected to the spring. When pressure is changed the diaphragm moves. So to keep a steady pressure the regulator simply controls the movement of the diaphragm.

What is regulated pressure on an air compressor?

Regulated pressure is the pressure you set for the airflow through the air compressor. The pressure regulator is used to regulate this pressure. The pressure should always be lower than the maximum pressure your compressor can handle.

What is the purpose of air regulator?

The purpose of an air regulator is to keep the air pressure of your air compressor to a constant level. Some air regulators also have filters to separate water from the air. These are called air filter regulator.

How do you adjust a regulator?

It is really simple and easy to adjust the regulator. After connecting the regulator to your air compressor turn the knob right to increase the pressure level. Turn the knob left to decrease the pressure level. By decreasing or increasing you can set the pressure to your desired level.

My Final Tips

I hope now it will be easier for you to get the best air regulator for compressor. For my final tips, I would like to say that always check the NPT size and pressure level of the regulator and match it with your air compressor before you purchase.

If you want, you can get only the pressure regulator or you can get the air filter regulator. The filter regulator will help you not only to regulate the pressure but also to separate water and debris from the air.

Finally, if you have some other questions regarding the air compressor filter regulator, feel free to ask me in the comment section. Thank you.
