Best Gas Air Compressor [Buying Guide 2021]

Let’s begin our journey with the crucial factors associated with gas compressors. Although they are technical terms with technical details, we’ll simplify them for non-techy guys. You will not need any engineering mumbo-jumbo dictionary to get them. Here we go …


CFM that is short for the Cubic Feet per Meter delivers the quantity of air in cubic feet to the air tool in one minute. It is a prime factor to consider whether your compressor is powered by electricity or gas.

The higher CFM rating provides a better running of the tools. It also enhances the ability to drive heavy tools and more than one tool at once.


PSI that is short for Pressure per Square Inch delivers the amount of pressure acted on an area of one meter. The tough jobs are PSI hungry, so they eat more PSI usually more than 100. For the junior tasks, 40 or 90 PSI can perform the job well.

The important thing you need to know is that you have to provide the pressure according to your tool capacity. Excess pressure supply can damage the air tool or result in its malfunctioning.

Tank Capacity

The tank is the reservoir of the gas or a gasholder. The tank capacity specifies how much content of the gas you retain at any time. With the larger container, you can have a greater amount of air for your pneumatic tools.

Also, it provides more backup for bigger tasks. You can keep doing the job without pauses for refilling. Yet, the larger size gallon also increases the overall cost of the product.

An interesting thing is that the tank size and portability have an inverse relationship with each other. It means that a larger tank size will reduce the portability factor. Smaller the footprint, the easier to carry the unit within the worksite or transport to other job locations.

You might consider the tank capacity according to your nature of the job and on-budget capacity. Here are some of the examples; 20 Gallons, 30 Gallons, 60 Gallons, or finally the Beastly 80 Gallon Air Compressors.


Almost all the gas powered air compressors have the noise factor to some extent. Therefore, they are mostly used in outdoor jobs. Although their loudness level lies within an acceptable range some of you may have to compromise this factor.

Stages, Single or Double

The number of stages determines how many times the piston of the pump compresses the air. Their double stage pumping will result in greater and better compression than the single stage.

Double stage compressors are efficient and deliver high CFM to the air tools. They are more versatile and can be used for more variety of tasks.

The single-stage buddies are the junior ones and are generally used in the smaller tasks where lower CFM is enough to run the tool.

But definitely, the single-stage compressors are more economical than the two-stage units. Cost or CFM, the choice is yours.

Oil vs Oil-Free

Oil vs oil-free air compressor, there are arguments for and against both of them. The tough jobs and durability demand a lubricated pump.

The oil-lubricated air compressors are machine-friendly as they extend the product life by reducing the friction between the mobile parts. Yet they require regular maintenance and replenishment which is an additional burden on your pocket.

While the oil-free air compressors are customer-friendly in terms of no additional cost or cleaning. But they have a relatively lower life span and less wear and tear of the components.

Price and Warranty

The pricing factor may vary a lot on our product list. This is because we are primarily highlighting the pas-powered feature. While the variation in the price is mainly due to a larger tank and accordingly the engine and pump specs.

Warranty! A bonus for the customer! If there is a warranty package offered, one may compromise the higher cost. There will be ecstasy for you when the product is available at an economical cost with an attractive warranty.
