Best Air Compressor

Air Compressor 5

Air Compressor Reviews

Air compressors are the ideal way to power your automotive and production tools when you want a quieter environment. Power tools that run from an air compressor are lighter in weight, more powerful, and faster, so there’s no reason not to switch over to pneumatic tools to make your work space a more pleasant and effective place. The high power of air that compressors provide offers significant gains in performance and productivity. When looking to purchase an air compressor, there are a number of factors to keep in mind. First of all, do you want your compressor to be stationary or portable? You will also need to choose between those that are powered by electricity and those that are gas-powered. Performance rating plays a huge role when looking for the right model, so check to see how they’re rated with PSI, SCFM, as well as horsepower. There are also a number of different pump types, such as continuous operation, single stage, two-stage, and oil-lubricated, just to name a few.

Air Compressor Buying Guide

Air Compressor 1

An air compressor is basically a device that is able to convert power (usually from a gasoline engine, diesel engine, or electrical motor) into kinetic energy. It does this by pressurizing and compressing air, which is able to be released in quick bursts when it is commanded to do so.

At the moment, there are a couple of air compressors on the market, which can cause a bit of confusion when it comes to choosing the one that is the best bet. For this reason, we decided to conduct a detailed research to bring you all the basic air compressors that are available in most stores around the globe (read below).

Piston-type compressors basically have tanks that shield compressed air. When the pressure in the tank reaches a certain level, the motor automatically shuts off. When the air begins to deplete from the tank, the pressure diminishes in the inside, and the motor begins to restart to construct the pressure back up. You are able to adjust the pressure settings to your requirements.

Types of Air Compressors

Single-Stage Compressors

Single-stage compressors basically contain one piston that compresses and sends air to the storage tank. This type of compressor is ideal for the majority of home users. This system is usually found on light-duty compressors with an extreme rating that is below 150 pounds of pressure per square inch.

Two-Stage Compressors

The two-stage compressors contain two pistons that compress and send air to the storage tank. The first piston pushes and compresses the air through a check valve to the other piston which compresses the air even more, and then sends it to the storage tank. This type of compressor is ideal for shops or for those individuals who need continuous use of a compressor. This system is normally found on commercial heavy-duty compressors that contain an extreme rating that is above 150 psi.

Portable Air Compressors

On the other hand, portable air compressors are the lightest and smallest compressors that are available on the market. Unlike the other compressors mentioned above, these compressors do not have a storage tank, so they must work continuously to provide air. Portable compressors are able to power small spray guns, caulk guns, glue guns, and are even capable of inflating tires and sport equipment.

The majority of air compressors are rotary screw, rotary vane, or piston type. When it comes to very large applications, centrifugal compressors are very common. Oil-less and oil-lubed are the main types of air compressor pumps. The oil-less system contains a technical development, but it’s more pricey, lasts less than oil-lubed pumps, and it’s louder than oil-lubed pumps. It has been noted that the oil-less systems provide a better quality of air in the long run.

Adiabatic Heating

Due to the adiabatic heating, air compressors require a disposing of waste heat method, which is normally some type of water-cooling or air-cooling method. Compressors are sometimes also cooled by oil utilization.

Usages of Air Compressors

Provides high-pressure clean air to fill gas cylinders

Provides moderate-pressure for school and office pneumatic HVAC control system valves

Provides moderate-pressure clean air to an immersed surface supplied diver

Provides tire filling

Provides a large amount of moderate-pressure air to different types of power pneumatic tools

Produces large amounts of moderate-pressure air for industrial processes that are large in scale


It is extremely important to follow the manufacturer’s safety instruction, maintenance, and operation of your compressor, including the safety gear instructions that come along in each unit’s manual.

Horsepower of Air Compressors

When it comes to the horsepower that a compressor’s motor produces, usually ranges from 1.5 HP-6.5 HP. There are more powerful compressors available, but they are usually used for industrial related applications. Horsepower motors that are higher usually are able to carry a heavy workload and yield greater psi.

Power Supply of Air Compressors

A Gas-powered air compressor is great for places where electricity is unavailable or very limited.

An Electric-powered compressor the very common and can be used in a place that has a ready electrical supply.

Size of Air Compressors

The storage tanks of compressors are rated in gallons. Large tanks are able to compress air at high pressures. The amount of air this type of item provides is always measure in cubic feet per minute. The majority of air tools have exact requirements when it comes to pressure and volume. In order for your items to function properly, all of the requirements must be met.

When you are trying to decide what compressor to purchase, think about the tools you want your compressor to operate. Select a tool that needs the highest CFM at the highest psi, and then add 50 percent to the necessary CFM.

Maintenance of Air Compressors

Compressors that are oil-lubricated will require that you change the oil on them on a regular basis. Make sure that you don’t forget to consult your manual to obtain the specific intervals.

Compressors that are oil-free require much less maintenance than oil-lubricated compressors and have sealed bearings.

Con of Air Compressors

It is safe to state, after mentioning all of the previous details, that air compressors have a handful of pros, but they also contain a thing that might be considered a con to a lot of individuals: its size. Yes, a great percentage of air compressors are very bulky looking. The good thing is that times are changes and tool are being transformed in appearance by manufacturers around the globe; therefore, if you shop around, you’ll be able to find a more compact air compressor that doesn’t take a lot of your space. There are a couple of compact air compressors available on various reputable online sites.

As you can tell, choose an air compressor requires more than simply selecting whichever one of the bunch, as all of them work in different form of ways. They comes with different price tags, which range from affordable to expensive; therefore, it is quite important to really look into how each air compressor that you are interested in functions, so that you can make the best purchasing decision.
