Powering pneumatic tools with an air compressor is one of the many applications of the machine.
The question is how can you successfully run different air tools with a single air compressor?
The answer lies in a feature called a pressure regulator.
This component will let you make adjustments to airflow pressure to deliver the correct quantity to the tool.
The difference between the pressure value your tool requires and the quantity fed by your air compressor will damage both.
In the following article, we have discussed in detail how you can adjust the air compressor pressure regulator accurately. Dig in to find out.

What is a Pressure Regulator?
The name is self-explanatory. A pressure regulator is a component of an air compressor responsible for regulating the unit’s pressure. The lever or knob helps you control the airflow’s quantity, allowing you to increase or decrease it as per requirement.
A pressure regulator also comes with a pressure gauge to help you monitor the pressure.
Large air compressors come with multiple regulators. You can adjust pressure with one of the many regulators available to enable the air compressor to serve a specific purpose.
Keep a close watch on an arrow indicator to avoid dropping or increasing the pressure too much. Both the extremes are damaging.
How to Adjust Air Compressor Pressure Regulator
First, install the air compressor and connect it with an air hose and the required tool. Give the manual a thorough read to get accustomed to the model and design of the air compressor. This will help you understand the settings better.
Once everything is in place, then comes the pressure adjustment part. You can execute the task without any hassle by following the steps listed below.
-
Turn On the Air Compressor
Plug the cord of the unit into a nearby power source to turn on the compressor. Make sure the power switch of the unit sits on “Off” before plug-in. Flip the switch to “On” position to start the air compressor.
-
Fill the Tank
Now, wait for a while to let the tank fill to its maximum capacity. The process won’t take long. Usually, it doesn’t take more than around 5 minutes to fill the tank to 125 – 135 psi.
The compressor will make hissing noises when the tank gets filled.
-
Check the PSI of the Targeted Tool
Next comes the PSI of the desired pneumatic tool. You need to check the PSI of the targeted tool to know whether it is compatible with the air compressor or not. If the tool requires a PSI value higher than your compressor’s limit, you will have to switch to a stronger unit.
On the other hand, you can proceed with the task if the selected air tools have lower PSI requirements. This action is called checking the tool’s psi compatibility.
Note: Most air-powered tools fall between 70 to 90 psi range. So, an air compressor between 135 -150 psi will serve you well.
-
Connect the Tool and Hose
Once the psi compatibility of the tool is up to the mark, connect the tool with the air hose. After that connect the hose to the air compressor.
-
Adjust the Pressure Regulator
Ding! Ding! It’s time to adjust the pressure regulator. Locate the regulator knob or screw first. Other than a few exceptions, most air compressors have this screw attached to the right side of the regulator. The knob may or may not have a locking mechanism, depending on the model of the compressor.
Pull the lever outward to unlock it. Pushing it inward will lock it back.
Turn the lever clockwise to increase the pressure. Closely watch the indicator and regulator gauge to monitor the increasing pressure level.
Similarly, twist the knob anti-clockwise to drop the pressure level. When the arrow reaches your targeted pressure value, push the knob to lock it.
Tip: Ensure your air compressor is set at least 20 percent above the PSI rating of the chosen air tool. This will ensure steady airflow, retain efficiency and prevent pressure drop.
Why Is Pressure Adjustment Necessary?
Pressure adjustment is necessary for the safety of your air compressor, pneumatic tools as well as project. Each pneumatic tool requires a specific PSI value to operate that is different from other air tools.
Without the correct pressure output, you might permanently damage the air tool and cut short the life of your air compressor. An inaccurate pressure level also bars the air compressor and the pneumatic tool from performing efficiently. This will also ruin your project.
Conversely, adjusting the pressure will allow the air compressor and your air tool to work in harmony, which will give you the best possible outcome. Plus, it will also reduce air consumption and save energy during each application.
Conclusion
A pressure regulator is a key component of an air compressor as it controls the airflow pressure. By altering the pressure output accurately, you safeguard the life of your tools, air compressor and job at hand. We hope the information shared in the article above will help you control the amount of air pressure output to correspond with the tool and application. Make sure you know the psi rating of the tool to know how much pressure you need to increase or decrease to achieve compatibility.
