Is A 20 Gallon Air Compressor Big Enough?

The 20 gallon air compressor provides more power than it usually is needed for a home garage. It also provides the reliability and efficiency that professionals would expect.

For use in pneumatic (air powered tool) equipment such as sandblasting, nail weapons, impact wrenches, and LVHP sprayers, this size of air compressor takes ambient air and exerts pressure under it.

They are also used in building construction, automobile factory, and workshops. They come in many shapes and sizes, and for your intended needs, it is important to get the right size.

It is also convenient to say “bigger is not big enough” when buying an air compressor. And some of the 60 and 80 gallon air compressors do not provide the required air for high-volume works such as car painting or grinder operation.

There is a need for a big air compressor without constantly waiting to charge/ refill to execute the job.

The choice of air compressor is greatly depending on the type of instrument that you plan to use with it. According to some completing bloggers, a 20 gallon air compressor is big enough to power a vehicle spray gun tool. While some other bloggers believe the same 20 gallon air compressors are not big enough to power impact wrench.

This is true if you low volume high pressure (LVHP) are used for paint sprayer head. LVHP sprayers work slower than bigger cousins. Although, they will get the work done but not as fast as might want.

A 20 gallon air compressor is big enough to execute ranges of the task but It is advisable to go for a bigger gallon air compressor if you are purchasing it for car painting tasks.

As mentioned above 20 gallon air compressor is the smallest size you can use with most compressors, and most of these air tools will still perform excellently. Although, the use of impact wrenches up to 1/2 inch with this size of air compressor might be a little difficult but it works with it. Also, the ratchet can run with a 20 gallon air compressor and 2 to 3 framing nailers can be used at once with this size. This will gives many operators to works at the same time.

So, a 20 gallon air tool is one of the best choices to purchase for the home automotive workshop. Typically, it has not only the horsepower you need but also spare air, that will allows you to perform higher volume tasks, such as die-grinder or cutting equipment.

It can also be used for small-scale painting projects, such as a side panel or a new hood. To paint an entire car without hours of practice, the 20 gallon is not big enough, as it is constantly drained to prevent water from entering the system. Such long delays make it difficult to achieve a smooth finish. This is an important job for you, so a bigger gallon air compressor is worth buying in this situation.

Is A 20-Gallon Air Compressor Suitable For Business Use?

Yes,

For industrial and commercial use, a 20 gallon is excellent. There are no regular starts and stops to allow the tank to be filled, thanks to the rate of air generated. And most time unplanned breaks are doing working activities.

A 20 gallon air compressor will be ideal for those that need a compressor that is more suitable for industrial use. This is because it can generate much higher air pressure than all smaller air compressors and it is a perfect tool for continuous working, without often stopping and starting, which is common to smaller air compressors. This makes a 20 gallon air tool suitable for industrial, business, and even stand-alone use.

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:

PSI

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

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.
