How to Pick a Good 20-Gallon Air Compressor?

Whatever the size of your tank is, there are some critical aspects that you should take into consideration when you’re picking an air compressor. And here are the most important ones:


The pressure that an air compressor is capable of is measured in PSI (Pressure per Square Inch), and this number will let you know with what air tools you can work.
And the higher the number, the stronger the pressure will be and consequently the heavier-duty jobs you’ll be able to tackle.
But generally, the most important thing is to match the pressure of your compressor to the specific air tools you want to run. Otherwise, your tools won’t run as efficiently.

Oil-lubricated vs. Oil-free

Oil-free air compressors generally have low running costs because they spare you the need to buy oil. They’re also easier to handle as they don’t require as much maintenance.
However, they’re not as powerful as oil-lubricated ones and not nearly as durable.


Noise levels are important because you don’t want to get a headache every time you operate your tool.
A tool with 80 dB or less would be good enough to provide you with solid performance without causing too much commotion.

Easy Tank Drain

Draining your compressor’s tank is an essential part of extending its lifespan and durability. So the easier it is to do it, the more you’ll properly maintain your unit, and therefore, the longer it will last.

How to Drain a 20-Gallon Air Compressor?

1. Switch off your compressor and unplug it from the power source.
2. Eliminate the internal pressure by pulling the tank’s safety valve to release all the pressurized air inside.
3. Locate the tank’s drain valve. Typically, you’ll find it at the bottom of the tank.
4. Open the drain valve and make sure you get all the moisture out.

How Long Can a Tank of a 20 Gallon Air Compressor Last?

Generally, air compressors have a long life. So from an average unit, you should get around 40,000 to 60,000 hours of work.
It depends on how frequently you use your unit, but it can last anywhere from 20 to 30 years.

Final Thoughts

Still not sure which of these is the best 20 gallon air compressor? Think of the tools you want to power with your compressor and what projects you want to tackle.
I’d recommend the DeWalt DXCMPA1982054 for the ideal combination of power, reliability, and portability. Although it’s not the most affordable, it provides you with a fantastic return on investment.
For a more affordable choice, you can go for the Campbell Hausfeld DC200000 as it’s powerful, has high pressure levels, and is very compact.
But for the best budget-friendly option that still offers portability and a lightweight and compact design, you should go for the WEN 2202.
