Items on this list have undergone extensive testing and approval by experts. Your task is to consider the following factors:

Oil-lubricated Vs. Oil-free

Air compressors are very fast and generate a lot friction. To control temperature, all compressors require lubrication. Oil-free compressors do not use any oil. Instead, they use special coated parts that reduce friction. They don't need oil filters or top-offs, which is why they are called oil-free. Although there is much debate about which compressor is best, the lower maintenance required by oil-free compressors make them the preferred choice for DIYers. This list includes compressors that are completely oil-free.


Although compressor noise is down significantly over the last few years, not all manufacturers see it as a top priority. It may take some digging to determine the compressor noise level of a particular model. You should look for the decibel rating (dB). Manufacturers often specify compressors with dBA (decibels per ear). This is a rating that's based on an average child’s hearing range. We'll use dB or dBA interchangeably for our purposes.

Performance Rating

Each air compressor comes with an SCM (standard cubic feet per minute) performance rating. The compressor's performance rating is a measure of how much air it can produce. You will need to use this number to determine the power output and compare it to any other pneumatic devices you intend to connect to the compressor. If you plan to use a nailgun with a rating above 4 SCFM, your compressor must be able to deliver that force.


Although the technology of DIY-grade compressors may seem fairly standard, there are many styles.
The most mobile air compressors can be used in a standing (or vertical) position. These compressors are preferred by DIYers who keep their compressors in one place, like a garage or woodshop.
The wheelbarrow compressor is mobile and can be used horizontally, much like a wheelbarrow. Pros who have to move a powerful compressor across a jobsite will find these products appealing.
The hot dog compressors are cylindrical, horizontal tanks that have been mounted on wheels. However, they don't look like a wheelbarrow.
The pancake compressors are smaller and have fewer wheels. These are great for carrying in a house or perched on the roof.

Hose Couplers

An air supply line connects compressors to tools. A coupler connects the hose to the tank. This coupler is often a quick-connect or quick-release coupler. It allows the hose easy access to either the compressor or the coupler. Some compressors only come with one coupler while others may have multiple. This won't be a problem if you only intend to use one tool. If you use multiple tools often, it is worth having them both connected to your compressor.

Tank Size

Because the compressed air that is left over will need to be stored in the tank, its size is important. The air can quickly run out in small tanks, which makes it difficult to work properly.


Two types of compressors are available: portable and stationary. The stationary compressor is larger, and can be used in a single location such as a workshop. These compressors are typically larger and can be outfitted with multiple nozzles that allow the compressor to power multiple tools simultaneously.
Because they are portable, air compressors can be used in a variety of applications and are more popular for residential usage. This makes them a great choice for your home's painting, roofing and decking projects. You can even use an air compressor to run a nail gun. It will greatly increase productivity than having to hold a hammer every day.


For continuous usage, high-horsepower compressors can be heavy and bulky. Low-power compressors may be lighter and easier to transport from one site to another or between projects. It is important to weigh the portability of the model against its power requirement.
Two to four large compressors might have wheels that are attached to a frame made of metal. This allows them to be lifted into and out vehicles before being wheeled to their destination. You can find home air compressors in a variety of shapes, including a pancake or hot dog shape, as well as a wheelbarrow with handles, travel-ready cords, and air hoses.
A portable compressor connects to the car's electrical supply, and provides emergency tire inflating. Portable air compressors are the smallest and most portable.


Airflow and pressure are the two main performance indicators for compressors. The standard unit of measurement for airflow is in cubic feet per minute (SCFM), and the pressure in pounds per sq inch (psi). Depending on the task at hand, which one you choose is most important will depend on your chosen method. For example, to inflate tires you need steady airflow and not too much pressure. To fire a nail gun it takes a brief burst with high pressure air. The most common DIY compressors can handle between 100 to 200 PSI. SCFM values will range from 2 to 3 for smaller compressors, to up to 7-10 for larger compressors. Look through your tools and determine the SCFM/psi required. Then, find a compressor capable of exceeding them by between 10-30 percent. The compressor manufacturer should list the SCFM at the correct PSI.

Power Source

Electric compressors are the most common, but they can also be powered with either electricity or gas. The electric compressors are more quiet, require less maintenance and can be used indoors. They are ideal for spraying paint with pneumatics. The fumes from burning gases can cause respiratory problems and could pose a danger to your health and safety. For tasks such as repairing the deck or building a fence, you can use powerful gas compressors outdoors.


What Size Air Compressor Do I Need?

There are many factors that go into deciding the size compressor you need. The way your pneumatic tools work will also play a role in determining the size of the compressor you need. A tool that operates continuously (such as a grinder or sander) requires a bigger tank than one that works only for short bursts.

What Projects Require A Home Air Compressor?

An air compressor at home is versatile and can be used for numerous projects. An air compressor can power a small nailer to replace door frames or baseboards quickly. You could pair the compressor with a cutting tool for cutting through steel sheets in automotive maintenance and duct repair.
These amazing tools can be used with frame nailers and sprayers as well as pneumatic drills. These tools can be combined with an air wrench to add torque to bolts or nuts that are stuck. You can run any tool you want with compressed air as long you have the right size of the compressor.

How Do I Determine What Pressure I Need?

Your tools will determine the pressure that you require. You can find the recommended pressures in your manual and make sure you choose an air compressor that is capable of handling your particular tool to meet your highest pressure requirements.

What Is A Portable Air Compressor?

Because it is portable, an air compressor can be used on construction sites or in the house. The compressor is used to draw air into the device, compress the air and store it. It can also be used to fill tires, blow out dust, and operate pneumatic power tools.

What Is ‘instrument Quality’ Air?

Compressed air that is not instrument quality does not contain moisture. This can cause damage to the control units or actuators in tools and other monitoring devices that use compressed air. Instrument quality air is typically compressed at 20-25 PSI.

How Do Air Compressors Work?

Although different compressors may have different ways of accomplishing the same goal, they all work in the same way. They draw outside air into a chamber and then compress it to increase the air pressure. Attach your pneumatically-powered tool to the compressor. The compressed air flows through the hose fitting and through the hose into the tool. You can do this by turning on your garden hose and closing the opening with your finger. The water pressure will increase due to the compressed water within the hose.

What’s The Best Use For Compressed Air?

It's great to have compressed air. You can save a lot on gas by using compressed air. An air compressor is also useful for cleaning up sawdust. However, I have found it to be the best way to get the crumbs from my car's nooks.

Do I Need A 50 Litre Tank?

It all depends on your purpose for using the air compressor. The largest tank is best if you plan to use your compressor to turn all of your power tools into pneumatic ones. You can save money by using smaller, more portable compressed air to inflate your tyres.

What Is A Good Air Compressor For My Car?

You will typically need an 12V compressor to power your car's cigarette lighter adapter. These air compressors are not suitable for use in an auto. They draw power from 120V outlets. While they can fill or wash car tires, or even help with car washing, the compressors won't be able to fix flat tires when you are away.

What Accessories Can I Fit To My Air Compressor?

There are many accessories and tools that you can buy for your air tool kit. You can get a lot of air tools and accessories, including paint sprayers and nail guns. But you also have the option to use air power tools such as drills and sanders and angle grinders.

What Oil Should I Use For An Air Compressor?

Motor oil should never be used with air compressor oils. You should instead purchase synthetic oil for your air compressor that does not contain the common detergents found in motor oils.
