What Is The Best Air Compressor?
More Detailed Air Compressor Reviews
This Wolf Sioux 50 Litre Air Compressor has a 50-litre tank, provides 116psi (pounds per square inch) pressure and a hefty 9.6 CFM (cubic feet per minute). The compressor also has a 2.5 HP (horsepower) motor. This product wins first place for the best air compressor for the UK market!
This is a powerful machine that can operate most air tools in garages and workshops including, nail guns, paint sprayers and other production machinery. It also inflates tyres with ease. The 50-litre tank means you can keep working for longer periods than with smaller machines.

Air Compressor Buying Guide
The best air compressor is a machine that converts power into pressurised air that is stored in a tank. The compressed air can then be used to inflate tyres or to fuel power tools or spray guns.
There are several home and DIY uses for air compressors. If you are a mechanic, DIYer, carpenter or painter then the best air compressor can make life considerably easier and help you get projects done more quickly and to a high, professional standard. Air powered tools are usually faster, lighter and more powerful than traditional power tools.
An air compressor can be used to inflate tyres on cars, trailers and bikes. It can also power a variety of tools such as nail guns and wrenches. They can also be used to operate paint sprayers to provide a superb even paint finish to everything from doors to cars. You can even use an air compressor for cleaning and degreasing.
The variety of tools that can be powered with an air compressor include brad nailers, chisels, hammers, drills, sanders, polishers, grinders, impact wrenches and ratchets.
When choosing the best air compressor for you there are some technical specifications that it is helpful to understand. Basically, the CFM, PSI and tank size work together to provide a steady supply of air.
CFM stands for Cubic Feet Per Minute and this is probably the most important measurement in choosing an air compressor.
This measurement tells you the amount of air the compressor can deliver per minute, in other words, how fast it can supply air. When combined with the PSI this tells you what you need to know to ensure that the air compressor you choose is capable of the uses you require it for. If a tool uses air more quickly than the compressor can supply it, you’ll have to stop working in order to wait for the compressor to catch up.
When choosing a compressor, consider the tools you will be using with it. Different tools require a different CFM so make sure the compressor can deliver what you need for the tools you choose. It is actually advisable to choose a compressor that can deliver a little more than you need. For example, if you wish to use a tool that requires 3 CFM at 90 psi, I would advise choosing a compressor that can deliver 4.5 CFM.
PSI means pounds per square inch. This is the measurement of the air pressure delivered by the compressor. Most home air compressors have a psi of at least 90 which is sufficient for most air tools you might want to use, including nail guns and sprayers. When choosing the best air compressor for your jobs make sure you have enough psi for the task at hand.
A larger tank will allow you to work for longer before the pressure in the tank drops and the motor kicks in to refill the tank. If the tank is too small, you may have to stop working to allow it to refill. If you need to work for longer than a large tank might be the best air compressor for you.
Other factors to think about when choosing an air compressor include:
Oil-free compressors need no maintenance. An oil lubricated machine will require topping up from time to time. Oil-free machines will probably be fine for light to medium use, however for professional or heavy use uses an oil lubricated compressor may last you longer.
Lightness and portability
Compressors vary in size, weight and portability. If you choose a larger model, ensure it has wheels for easy manoeuvrability. Light models are easy enough to carry around.
A long cable makes it easier to use your compressor in a variety of places.
Some compressors have one outlet, some two. Two outlets obviously mean two people can use the machine at the same time but also that one person can have two tools set up without having to change attachments.
Many compressors come with a range of useful tools and many more air tools can be purchased separately. Just remember to check that the compressor you choose has the capacity to power the tools you wish to use.
What types of air tools can be used with air compressors and how much CFM do they require?
There are a variety of air tools that can be used with an air compressor. The CFM required for the most popular tools are listed below.
Trim nailer 0.9 CFM
Framing nailer 2.2 CFM
Chisel 3-9 CFM
Hammer 3-9 CFM
Drill 3-6 CFM
Angle Grinder 5-8 CFM
Impact Wrench – 3/8″ 3 CFM
Impact Wrench – 1/2″ 4 CFM
Orbital Sander 6-9 CFM
Airbrushing 3-11 CFM
How do you use an air compressor and is it difficult to do?
All air compressors are all slightly different and you should refer to the manufacturer’s instructions to ensure you use yours safely and without causing harm to yourself, the compressor or your tools. However, the following guide will explain the general procedures required when using an air compressor. You will see that they are quite simple to use once you get the hang of what to do.
Firstly, you should get together all your supplies. Make sure you have access to a power source, ensure you have oil if your machine requires it and gather the tools, supplies and safety equipment you need. You should wear safety goggle when using your compressor for most jobs. In addition, ensure that your work area is clear from obstructions and hazards.Check your air compressor
Before using your compressor, you should check that it is in good order. If the compressor requires oil, check the level now. You should make sure the compressor is on a stable, even surface. Always ensure that the machine is switched off before connecting it to a power source.
Make sure the drain valve is closed at the bottom of the air tank and turn it on. Then turn the pressure gauges to the pressure you require.
Check the built-in air gauge and make sure the compressor shuts off automatically when the air pressure reaches the right pressure.
Adjust the air control valve to match the maximum allowed air pressure on the air tool that you will be using.
Connect your air tool to the hose and you are ready to begin work.
Once you have finished work, shut off the pressure gauge and switch off the machine. Open the pressure relief valve to release any air left in the tank. Store your air compressor in a dry place with adequate ventilation where it will not be damaged.
