Pressure In An Air Compressor | Air Compressor


Back in the day, you’d typically see air compressors only in the workshops and home garages of the most devoted DIYers and mechanics. They were tools reserved for the professional craftsman.

Nowadays, however, with the surfeit of smaller, newer-generation air compressors, everybody can take advantage of the benefits that these useful tools bring.

While air compressors are primarily used to power pneumatic tools for a multitude of applications, there is so much more you can do with them. Our best pick for use in different applications is the Porter-Cable C2002, but don’t take our word for it willy-nilly.

Pneumatic tools make your DIY projects easy, and air compressors allow you to take advantage of their considerable power. Plus, air compressors really aren’t rocket science to put together and operate. Simply plug in the hose, the electrical cord, and keep an eye on the pressure gauges to ensure you are getting the right amount of pressure in your pneumatic tool. Voila! You’re basically ready to take on the world one DIY project at a time.

If you’re switching around tools in the middle of a project, be sure to adjust the pressure and release the valve once you’re done to ensure that you remain safe.

Simple enough, right?

Now, we’ll take a closer look at the nitty-gritty of things. Particularly at how to effectively load and unload pressure in your chosen air compressor – be it a big with 60 gallon or with a small tank.

If you want to take advantage of the benefits of using pneumatic tools, it’s important to find out how much pressure is required for you to use your tools in a safe and effective manner. You can find this information on your pneumatic tool – do check for engravings, stickers, or signs on the tool’s handles, or check the manual to be absolutely sure.

It’s important to take note of the maximum PSI levels of your tools to make sure they function as expected. Also, each pneumatic tool does have its own specific PSI; thus, it would be important to remember to adjust your PSI as you work with different tools.


Air compressors possess regulator knobs you can turn to ensure you are using your pneumatic tool at its recommended PSI – increase it and decrease it as necessary to match your tool. This is simply and easily done by turning the air control valve in a counterclockwise or clockwise direction until the gauge from your air compressor has the right PSI reading. Then, once pressurized air is flowing through the hose, you can use your pneumatic tool. Your air compressor will automatically refill itself with pressurized air as you use your tool.

That said, let’s take a look at how the pressure in air compressors are actually loaded and unloaded.


A great majority of air compressors are powered by induction motors for reasons of being more efficient.

The most common loading and unloading principles for air compressors (and other displacement compressors for that matter) are to produce air (load) and to not produce air (unload).

Every time air is needed, a signal is sent to a valve that triggers the compressor’s inlet to fully open up.

This solenoid valve is either completely opened, this way “loaded”, or completely closed, or “unloaded”. There is no middle ground, so to speak, when it comes to this principle.

On the other hand, smaller air compressors employ a traditional control principle, which uses a switch to adjust pressure located in the pressurized air system with two values available for selection. There exists a value for minimal pressure – that is, “loaded”, and another for maximum pressure, or in this case, “unloaded”. The said air compressor will work with the values in between the limits that are set depending on the air requirement.

If air requirements are minimal, the air compressor will go into a state of time-limited idling (typically set beforehand), until it stops completely. The compressor will not restart until the pressure has decreased to the minimum value it has earlier been set to.
