To find the most suited 20-gallon air compressor for your needs, you need to consider some points or features. These points will help give a better understanding of what kind of work you want to do with the air compressor and the type of machine you need in order to achieve it.
Firstly let us look at the different types of air compressor out there:
This one is the best choice for light work. It has a cylinder that pumps the pressured air into the tanks has a 120 psi.
This kind of air compressor is best for heavy-duty. These have 2 cylinders and 90 psi. The tanks handle up to 175 psi.
The air tank capacity is an important point that should be looked into. You need to choose this capacity, depending on the load or level of work you are attempting. Smaller tanks are suitable for light work, while a frequent user will need a larger air tank.
A 20-gallon air compressor should be able to hold more compressed air, but how long the air will last in the tank is mainly decided by the pneumatic tools.
CFM stands for Cubic feet per meter. Every model of air compressor has a CFM rating. This rating is very important in judging the quality of the compressor. The CFM rating defines the amount of air that will come out of the air compressor. And the pressure is higher when the PSI is lower and vice versa.
The air pressure is measured by PSI. And the PSI of the air compressor is very important as it defines the amount of pressure it can handle. Especially if you are someone who needs a high-pressure air compressor, this is something that you should definitely consider to avoid any inconvenience.
The motor has the role of keeping the air in the tanks. If the tank is very big in size, filling it up with high air pressure can be a lengthy process. This will slow down your work. However, if the power of the motor is high, then it can quickly refill the tank, making it ready to use within seconds.
The duty cycle of the compressor defines the amount of time it runs over a 10 min duration. A below-average compressor has a 50% duty cycle, which means it runs for 5 minutes out of 10 minutes. And a good quality compressor has at least a 75% to 100% duty cycle.
They usually have two types of power supply:
These are the best option if portability is an issue. You can use them anywhere without any source of electricity. Therefore, you do not need to worry about finding an electricity supply if you have to travel for work.
However, it can be dangerous to use where there is less ventilation as they can emit fumes that are harmful to your health.
These models are less suitable for industrial work as they require an electric outlet to be present nearby to function. Due to being run on electricity, the portability of these models is an issue.
However, they do not make any noise at all and are quite cheap as well. So if you're looking for the best 20-gallon air compressor for the money, an electric compressor will be the way to go.
A 20 gallon air compressors require much more power compared to other portable air compressors as they have much bigger motors. Most of the models require a minimum of 120v of power.
In order for it to function properly, you will need a 20A circuit. If the circuit requirement is not met, then the fluctuation of the power supply can cause a short circuit. This fluctuation can also shorten the lifetime of the motor.
The feature of the air compressor is a very crucial one. There are two types in the market oiled and oil-free. The oil-free one is quite new in the market. Teflon is used instead of oil to count the inner part. It slowly wears off with usage and eventually stops working.
And the oil-less models are ideal for light work. These models are usually popular for low price, being lighter, and having a low maintenance cost. At the same time, the oiled models are for industrial use and are made for heavy-duty. They don't make noise and are more durable and cool.
A 20-gallon air compressor is a very useful tool that will help you do a lot of hard tasks with ease. It can be a bit difficult to learn how to use it. Setting up the line and meaning of the gauges is not so easy to do, but once you get the hang of it, it'll take you just a few minutes to set this thing up.
This can be a complementary tool with other air tools, such as a nail gun. If you are someone who has to work with nails guns, then an air compressor can help you out a lot.
No need to spend on expensive battery-operated nail guns. Instead, you can use pneumatic nail guns with an air compressor.
Mostly people prefer it as it is because of the lightweight factor. This makes it easy to handle, and it can be used for a longer period of time. Air pressure lasts longer than the charged battery.
You can also make your own spray gun with it. Painting can be much easier and fun with an air compressor. It will be very cost-efficient and will give a professional touch to your work as well.
Air compressors have a lot of industrial use. The 20-gallon allows it to store a lot of compressed air; therefore, it can run for a long time without stopping. This means it is also efficient to work with.
If you are a DIY enthusiast, then you will love this tool. Usually, people who do their own repairs struggle with removing bolts from tight space or if it has rusted. But if you use an air ratchet tool with an air compressor, this work can be done within minutes.
Apart from these, an air compressor can be used with many other tools. You can use it for cleaning stuff or use it as a leaf blower. The air pressure is much more long-lasting. Therefore using tools with an air compressor will last longer than battery-operated tools.
To conclude, the 20-gallon air compressor is a brilliant tool that you need to get! The best part about this tool is that you can use it for multiple purposes. So this means you will have one tool but can do multiple tasks. This is money spent wisely!
If you're still confused about any aspects of an air compressor, here are a few commonly asked questions that we have answered for you.
The size of the air tank obviously matters as it determines the amount of air that can be stored and also the pressure it can take. If the air tank is small, then it means the motor has to work more, putting a lot more pressure on the motor. Constant refilling will also take time. Therefore, for industrial use, make sure to get a large air tank.
It is ideal for industrial use. Unlike smaller air compressors, it won't stop and slow the process of work. The 20 gallon air compressor can produce a lot of air pressure as well. If you're a DIY enthusiast, you can also use it on smaller painting or nailing projects.
It is more ideal for inflating tires. This machine is simply not made for running an impact wrench. However, an impact wrench of 1/2 inch can be run with a tool like this. 3/4th and even bigger can be run, but you need to get the full power of the 20 gallon air compressors.
Depending on the maintenance, 1 gallon of the compressed air will last approximately a year in the tank. So accordingly, a 20 gallon tank will last 20 years. But obviously, it has to be properly maintained. Make sure it does not rust and to drain the tanks once in a while.
The tanks do not specifically have an expiry date, but they do go off after a while. That is why the tanks should be maintained and monitored as often as possible. If the tanks are not properly maintained, then it will form rusts. Therefore, the tanks should be drained to keep it dry, which increases the tank's lifetime.
We hope the article has provided useful information and helped you get enough knowledge to help you make the decision to choose the best 20 gallon air compressor.
