Best 20 Gallon Air Compressor [2021 Ultimate Buying Guide]

There are certain factors that play a very important role in the efficient working of your tool. So, the below points will clear the fog in your mind about what to look for in a desired best 20 gallon air compressor.

Cubic Feet per Minute (CFM)

It is a measure of how fast and how much air is supplied by the compressor to the pneumatic tool. Thus higher CFM results in a higher volume of air output at maximum speed.

The reason I consider CFM as the 1st important factor is because a huge range of tools demands a large amount of air at an astonishing speed to work precisely.


The noise level plays an important factor especially using the product indoors. The noise level also depends on the type of pump and its design in a compressor.

For hassle-free working, you should use a quiet air compressor with a tolerable range. Another way is to apply tips to make your air compressor quieter.

In this way, you’ll avoid getting to the bad side of the neighbors and also have a peaceful shop just for your dear customers.

Tank Size

The tank or gallon size determines the volume of gas enclosed in the cylinder for a longer period of operation.

The higher capacity means extended tool working time and less frequent refilling. Thus, ultimately results in time-saving and makes your work faster.

Space & Portability

Mobility of the compressor with-in site and from site to site is essential to the job. Thus a smaller footprint and lower weight along with the wheels make the equipment perfectly portable.


Durability may depend on the design and the quality of material used in the vital parts of the product. Enhanced durability means a longer life-span, frequent use with accurate, consistent, and tough performance.

Oiled Vs Oil-Less

If I were to talk about oiled vs oil-less compressors both have their benefits and flaws depending on the usage and requirements.

Oil-free has the advantages of maintenance less, cost-free, and easy to clean. While oiled compressor has advantages of the noise-free, longer life of pump at tough jobs.


Despite all benefits and advantages, the budget factor still retains its importance. Thus before pressing the big buy button compare the benefits and cost of the compressor. The final satisfied selection will be made only when both factors get balanced.
