How to Adjust the Air Compressor Pressure Regulator?

Air compressors can be very useful tools – whether you use them at home or for commercial purposes. But just like with any other unit, you need to make sure that you use it correctly. And in this case, it might mean that you should know how to adjust the air compressor pressure regulator. This way, you’ll ensure that the device works smoothly.

So, how can you adjust the pressure regulator and make sure that the unit works the way you want it to? This article is going to tell you.

What Is an Air Compressor?

How to Adjust the Air Compressor Pressure RegulatorAir compressors are units that have pressurized tanks where they store potential energy. Basically, they can convert power through various means, such as diesel, electric motor, gasoline engine, and many others. As such, a unit like this can store air for a long period and this is going to result in very high pressure – whether we’re talking about a big or small air compressor.

What Is a Pressure Regulator?

Pressure regulators are parts of air compressors, and they are very important components. When you use the air compressor, the pressure regulator is going to increase or decrease the airflow that comes out of the tank. Therefore, they are necessary for proper control.

The pressure regulator is a monitor. This is going to display the amount of pressure it releases. Basically, the monitor is a key part of properly operating the air compressor because the tools you use have a PSI number. So, when it comes to using the right PSI number, the monitor will allow you to set the right number and run the air compressor accordingly. Without this, the device you want to use may not work the way it should.

It’s important to know that some air compressors have more than one pressure regulator, especially when the unit is a large one. Because they are bigger, they may be used for multiple things – so, different regulators are needed in order to operate each particular tool. Keep in mind that each regulator has to be adjusted accordingly.

Why Is It Necessary to Properly Adjust the Pressure Regulator?

You may be wondering why you need to adjust the pressure regulator and why the right pressure is such an important consideration.

Well, it’s all for safety reasons. Without using the right pressure, you may end up pushing your air compressor to the limit. This could be very dangerous as it may harm the unit and it might not work anymore. Especially if it’s an older model we’re talking about, you risk causing it to break if you don’t use the right pressure.

If you operate the air tools according to the minimum pressure set by the manufacturer, you will extend their lifespan. It’s the same for air compressors – if you make the proper adjustments, then the air compressor’s cycle frequency will be reduced, increasing its durability as a result.

Additionally, a pressure regulator may ensure that you’re using less air. Reducing air usage may end up decreasing the energy costs, so you’ll also get to save some money in the meantime.

How to Adjust Your Air Compressor Pressure Regulator?

Adjust Your Air Compressor Pressure RegulatorFirst things first, before you adjust the pressure regulator, you have to check whether you need to calibrate the settings. Make sure to read the manual that comes with the unit before you change the settings. It will give you a more general idea of the compressor and model. Some models have a fixed differential value below the unit’s regulator switch.

If you look near the valve housing, you will find a note that gives you more information on the matter. The guide from the manufacturer should also offer you extra details about the differential value.

Now, here are the steps you should go through to adjust the air compressor pressure regulator:

1. Turn on the Compressor

The first thing you will have to do is connect the air compressor. After doing so, turn on the unit.

2. Make Sure the Tank Is Filled with Air

Now, allow the unit some time to work until the tank is filled with air. Make sure the tank is full of air. You will figure this out due to a sound the unit will make after you turn it on.

3. Look at the PSI

Then, connect your air tool and check out whether the PSI of the tool is higher than the one of the air compressor. If it is, then don’t use it with the compressor. Only use a tool when the PSI requirement is lower than the one of the compressor.

4. Connect the Parts

After ensuring the compatibility, connect the air tool with the air hose, and then the air hose with the compressor.

5. Adjust the Regulator

You can now start adjusting the pressure regulator of the unit after you connected the parts.

6. Find the Knob

There should usually be a knob on the regulator’s right side, but of course, it all depends on the model you own. Some knobs have a locking feature too – you can unlock by pulling it out and lock by pushing it in.

7. Turn the Knob

Next, turn the knob clockwise if you want to increase the pressure or anti-clockwise to decrease it in the compressor.

8. Find the Right Pressure and Lock the Knob

Once you find the right amount of pressure, you have to push in the knob and lock it, and your unit will operate properly.

Final Thoughts

So, whether you have a large or small air compressor, it’s essential to know how to adjust the pressure regulator. This way, your unit will operate properly. Hopefully, this post has given you the information you need.

Jason Parker learned that being a cyclist doesn’t only mean riding – he decided to build his own workshop for maintenance and fixing. Soon enough, he realized that there is no decent workshop without air tools (of various types). Through research, trial, and error, he decided to gather all his knowledge (so far) into these blogs and guides.
