Best 20 Gallon Air Compressor Buying Guide

Low Noise Level

Being that the noise level of your air compressor is an important factor in your purchase, you should definitely check for this.

Different air compressors have different noise levels depending on the model and design, and so you should check for the decibel rating. If there is none, you can try testing the machine and be sure that you are satisfied with the output.

Power

The motor power of your air compressor is also important as it determines just how useful your air compressor would be. The tank motor stores air in the tank and this process can be time-consuming since the tank capacity is large.

With a powerful motor, however, this process is less time-consuming and can fill the tank much faster. You may also want to read our articles about Best Quiet Air Compressor 2021 and Best Most Quiet 30 Gallon Air Compressor

Cubic Feet Per Minute (CFM)

CFM is short for Cubic Feet Per Minute. It’s a measure of the amount of air the air compressor gives out in a minute. This measure is important as different pneumatic tools have different CFM requirements. And so depending on the CFM requirement of your tool, choose the CFM rating of your air compressor accordingly.

The CFM of air compressors isn’t a constant as it differs at different PSI levels. CFM is higher when the PSI is low, and vice versa. When purchasing an air compressor for your tools, it’s wise that you go for one that gives 20% more airflow than what the tool requires.

Size

The tank size you go for depends on the task you intend to use it for and the tools you intend to power up. 20-gallon tanks are not large-capacity tanks, and so are best for running low load air tools.

These are your best choices if you intend to do small jobs around the house. For more serious jobs, bigger tanks are recommended.

Max Air Pressure

The maximum air pressure rating tells you the amount of pressure your air compressor can handle inside the tank. It’s important as different tools have different pressure requirements and can only function well if the pressure that is supplied to them is what they need.

PSI (Pounds per Square Inch) is the unit for measuring maximum pressure. It’s different for different models and the advantage of having a machine with high PSI is that it can power up multiple tools simultaneously.

Source of Power

They are two types of air compressors based on the power source;

Gas Powered Compressors

Gas-powered air compressors aren’t attached to a cord and are the best options for those who need a portable machine. They are useful in places with no electricity, making them flexible. Their downside however is the emission of fumes, making them bad for indoor use.

Electric Air Compressors

Electric-powered air compressors can be used indoors as well as outdoors, but they require an electrical outlet. They are quieter than the gas-powered types of air compressors and are also usually  less expensive. They are however limited to areas with electricity and are not suitable for heavy-duty jobs.

Oil-Free or Oil Filling

Oil-free air compressors have Teflon coating in the inner compartments. This allows them last for as long as 2000 hours of use. they are cheaper, easy to maintain, and weigh less.

Oiled compressors are however less noisy than oil-free air compressors. And so they are the best to be used in residential areas to avoid causing so much disturbance to your neighbors.

Oiled air compressors can also withstand pressure from heavy-duty usage. Note that oiled compressors are not as easy to maintain.

So when making a choice, note that oil-free air compressors are the best option for you if you require something lightweight with less maintenance.

Oiled compressors on the other hand are the best for you if you would be working for long time as they are more durable and quieter.
