Air Compressor Buyer’s Guide
An air compressor is a machine that converts power into pressurised air and stores it in a tank, ready for controlled release to serve a multitude of purposes.
There are many home and DIY uses for air compressors. If you are a mechanic, DIYer, carpenter or painter then a good air compressor can make life considerably easier and help you complete projects more quickly, more efficiently and to a higher 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 power a variety of tools such as nail guns and wrenches. It can be used to operate paint sprayers providing a professional paint finish to anything from doors to cars. An air compressor can even be used for cleaning and degreasing.
Tools that can be powered with an air compressor include drills, hammers, chisels, sanders, polishers, grinders, impact wrenches, ratchets and brad nailers.
When choosing an air compressor there are some technical specifications that are helpful to understand. You should consider CFM, PSI and tank size. These work together to ensure a steady supply of air is always provided.
CFM stands for Cubic Feet Per Minute. It tells you the amount of air the compressor can deliver per minute, in other words, how fast the air can be supplied. 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, it is important to consider the tools you will be hooking it up to. Different tools require different CFM’s 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 the tools require. For example, if a tool specifies 3 CFM at 90PSI, you should choose a compressor that can deliver at least 4 CFM.
PSI stands for pounds per square inch. This is a measurement of the air pressure delivered by the compressor. Most home air compressors have a minimum PSI of 90, and that is sufficient for the most commonly used air tools. When choosing an air compressor for your jobs ensure you have enough PSI for the task in hand.
A larger tank will allow you to work for longer before the pressure in the tank eventually 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.
Other factors to think about when choosing an air compressor include
Oil-free compressors require little or no maintenance. An oil-lubricated machine will require topping up from time to time. Oil-free machines are fine for light to medium use, but for professional or heavy use 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 longer cable makes it easier to use your compressor in more places.
Some compressors have one outlet, others have two. Two outlets mean that two people can use the machine at the same time, or 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
Air-brushing 3-11 CFM
How do you use an air compressor and how difficult to use is it?
All air compressors are 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. The following guide will explain the general procedures required when using an air compressor. They are quite simple to use once you get the hang of it!
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 goggles when using your compressor for most jobs. In addition, ensure that your work area is clear from obstructions and hazards.
Before using your compressor check that it is in good order. Check the oil level in the compressor is adequate. Make sure the compressor is on a stable, even surface. Ensure that the machine is switched off before connecting it to a power source.
Make sure the drain valve at the bottom of the air tank is closed 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 and somewhere it will not be damaged.
