And today I’ll be shedding light on of their kind “the best 20 gallon air compressors”. Now, these beasts are a combination of higher raw power, rock-hard durability, jaw-dropping performance, and portable size for ease of movement.
They are specially built for serious people like you and us. Those who have to do some serious heavy-duty work and they don’t hesitate to use power-hungry tools to make your work epic and you as a professional.
Here we have written down a 20-gallon air compressor buying guide. It’ll help you compare and short-list the right compressor according to your needs, tools, and job as well.
Best 20 Gallon Air Compressor [Year] [Buying Guide]
Certain factors 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 the 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 that 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.
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. This ultimately results in time-saving and makes your work faster.
Space And Portability
Mobility of the compressor within the 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 the material used in the vital parts of the product. Enhanced durability means a longer lifespan, and 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 needing less maintenance, being cost-free, and being easy to clean. While oiled compressor has the advantages of being noise-free, having longer pump life, and can handle heavy-duty jobs.
