Buying Guide

Even if you already have an idea about the best air compressors, it is still important that you know a bit about its features. This buying guide can help you make the right decision when looking for an air compressor.

1. Size

When it comes to size, we are not talking about the actual size of the product. This is about the storage tank of the air compressor. If you are getting a small model, 4 to 6 gallons would do the trick. The smaller tank is already useful for various projects like airbrushing and more.

If you need something for tires, you will need a larger tank with a higher pressure. They are often used for automotive work as well as various remodeling projects.

2. Display

For the display, you want something that would provide you all the details that you need when operating the air compressor. You need to look for a model with a digital gauge because it will allow you to program the air compressor. It means that it would as soon as the pressure that you set is reached.

3. PSI Levels

For the PSI levels, you would want to get something with higher PSI, especially if the engine has the high horsepower. Higher horsepower will be able to create more air pressure and it can be measured in PSI.

Higher PSI would mean that the compressor can store much more air in your tank, which would allow you to use the air tools longer. You don’t want to buy something that would run out of air after a couple of uses, especially if you are going to use it for tire inflation.

4. Auto Shut-Off Feature

This is one of the most important features that you need to look for when it comes to air compressors. You need to look for a model with an auto shut-off feature. How does it work?

You need to preset a pressure level that you want and once the limit is reached, the device will automatically shut down. This is a very important feature so make sure that you search for this when buying.

At the end of the day, searching for an air compressor will depend on how you plan to use it. You have to remember that these portable air compressors cannot be used for heavy-duty work.
