Best 20 Gallon Air Compressors review guide Of 2020 – An air compressor is a must-have in the garage or workshop if you like doing things yourself instead of hiring someone to do it for you. And for home use, the perfect size most prefer is the 20-gallon variety. If you think about it, there are multiple reasons for doing so. 20-gallon air compressors are versatile, portable, and most of all affordable.

A 20-gallon air compressor can come in handy for a plethora of uses. Whether it’s powering that nail gun or just inflating the kiddie pool. It can become challenging for the layperson to make the right choice, as the trouble is, there is a large variety of these products out there in the market. But don’t worry, we’re going to make sure that doesn’t happen to you.

Today we’ve gone ahead and reviewed some of the best 20-gallon air compressors in the market that you can buy, in our Best 20 Gallon Air Compressors Review Guide For 2022-2023.

Buyers’ Guide for Best 20-Gallon Air Compressors:

You need to have an idea about the different facets that need to be considered while evaluating the performance of air compressors, to make the right decision. And to help you do just that, we’ve included this comprehensive buyers’ guide that’s meant to help you out.

You’ll be ready to choose the air compressor that can fulfill all essential needs, once you’ve gone through all the finer points of this guide. Let’s get to it then.

The Motor:

The most crucial part of the device is your compressor motor, and rightly so. It is the motor that is responsible for compressing air into the tank and also refilling it. So you can realize that it’s the motor that undergoes the greatest amount of use in a compressor.

As a result, you need to look for units that have a powerful and high-quality compressor. This is essential to ensure that you don’t end up spending too much time and money on repair work and maintenance. For best results, settle with a motor that connects to the compressor via a belt. And make sure of any lubrication requirements of the motor.

PSI And CFM:

These are two very important metrics to look after when you’re choosing the right air compressor. PSI and CFM are the numbers that define the power and speed of your compressor.

PSI stands for Pounds-Per-Square-Inch, and CFM denotes Cubic-Feet-per-Minute. CFM is essentially the rate at which air is pumped out of the compressor. Naturally, the higher the CFM, the faster the tank will be depleted.

PSI, on the other hand, represents the amount of force per unit area that the compressor can deliver. Naturally, CFM and PSI are inversely related to each other: the more air that you let out, the lesser will be the pressure of the device and vice-versa.

You can find PSI and CFM readings on the manufacturers’ website or the packaging for each model. Many units even have the metrics printed against the air-tank.

Tank Capacity:

When it comes to air compressors, the most noticeable aspect is the tank. In our guide, we’ve focused on 20-gallon models, but there can be compressors with lesser or greater capacity.

Understandably compressors that have a larger tank will be able to hold a more significant amount of air. This allows them to work for more extended periods without the need for refilling. Plus, they are also able to maintain their peak PSI for more extended periods.

So if you are going to use the compressor with a tool that requires a large amount of power, then go for one with a large tank. However, for low-powered applications, a smaller tank will suffice.

Oil-Free Or Lubricated:

When going through compressor listings, you’re bound to notice that some air-compressors are oil-free while others are oil-lubricated. Both types have their advantages and disadvantages, and which one you go with depends on your needs and preferences.

Oil-free compressors are generally cheaper to maintain. They don’t need periodic oil replacements and are also better for the environment.

But don’t think that means oil-lubricated ones are out for the count! Oil-lubricated compressors undergo less frictional wear-and-tear and hence last longer than oil-free compressors.

Noise Levels:

Let’s face it: air compressors are not meant to be quiet pieces of equipment. They are designed to operate under industrial conditions; hence noise dampening may not be considered necessary.

Nevertheless, if you’re looking for quieter compressors, then you won’t be disappointed. In general, electric motors are designed to be quieter than ones that run on gas. On the flip side, gas motors are more powerful.

How to Use a Compressor: Just the Pro Tips:

• Make sure your compressor has the PSI and SCFM to keep up with the tools you’re using
• Avoid gas with ethanol or use a stabilizer
• Add more hose instead of extension cords for greater reach
• Run the compressor with the drains open for 30 minutes to break in the motor
• Check the air filter frequently and replace when it gets too much build up
• Drain the tank at the end of the day to release moisture build-up
• Check the tank expiration date to avoid bursting
• Check the duty cycle and make sure it matches your applications
