What To Look For When Buying An Air Compressor?

An air compressor is a device that includes mechanical systems and machines. It is used to increase the pressure and temperature of the air stream by reducing its volume. Compressed air is a type of energy that creates pressure and is used for human activities.

And if you are in need of a good air compressor, then follow our article today about what to look for when buying an air compressor! All the information given will make you stunned!

But, have you known what an air compressor is used for?


Manufacturing Industry

Air compressors are used in pneumatic lifting equipment for cargo handling. They make it easier for humans to transport goods of hundreds of tons.

They are also used for cutting and welding, which provide enough power and energy to cut through hard objects.


Compressed air creates kinetic energy to transport concrete or it is used in combination with drilling tools to drill holes and walls.

Environmental Protection

It can control the effluent flow and the oxidation of the sewage tank to increase the amount of oxygen in the water, and thus change the quality of water.

Besides, compressed air can create energy sources that are used in the manufacturing of generators in wind power plants or in promoting the combustion of incinerators.

Maintenance of Cars, Motorcycles, and Bicycles

This is the most obvious example as you can encounter it in daily life. Air compressors can be used to clean dust, dry after washing or inflate the tires.

Mining Industry

Can be seen as ventilation, compressed air has a very strong momentum that can operate gas-powered equipment to probe the depth.


Few would expect that air compressors are important in medicine. To be more specific, it is used to disinfect. Also, many medical devices like blood analyzers, dental milling machines, autoclaves, etc. need air compressors to operate.

What To Look For When Buying An Air Compressor?

As stated above, air compressors come in many types with different uses. Thus, to pick the right one for you, here are some factors you need to take into consideration before making any purchase.

Types of Air Compressors

This factor depends largely on your intended use. Some small tasks like installing PCV valves or tune-ups that you can do at home require few or no tools combining with the air compressor.

In the meantime, such hard jobs as removing tough bolts or rusty components may need some tools equipped with to do it easier.

Likewise, if it is for industrial use, a powerful air compressor is better than a light-duty portable one, which is usually used for inflating tires or blowing leaves or dirt.

Tank Size

Obviously, this is considered based on the heaviness of your duty. To be more specific, the smaller tank size is movable and portable, allowing you to apply it with rubber wheels to make it easier to move around. This is completely suitable for those whose works require a lot of moving but little power.

In contrast, a bigger tank size is harder to move around but is able to facilitate multiple air tools at the same time for a longer time.

Pounds per Square Inch (PSI)

This unit of pressure shows how powerful the compressed air is.

This is an important factor as too high PSI can damage your tools, but too low PSI means your tools are not provided with enough power to operate.

Cubic Feet per Minute (CFM)

It is this factor that determines the flow rate of the compressor or the amount of free air produced at a given level of pressure.

Hence, the air compressors with higher CFM rate can provide more air and operate more tools at once.


Air compressors are applied in a variety of industries and have become a useful device. Thus, choosing the right air compressor for your job is not an easy task as it depends on many different factors. Hopefully, our article on what to look for when buying an air compressor today will help you pick your perfect one.
