Air compressors today are very useful tools. At home, they can be used to inflate a ball, bicycle or even car tires. While in the industry they can be used to drive other tools. In this guide, we will teach you how to choose a suitable air compressor for either domestic or industrial use, as well as the differences between each one.
Air compressor for spray painting cars
California Air Compressor is the best spray painting cars. There are many kinds of car paint spray on the market but the California Air Tools Compressor is the best sprayer.
What size air compressor do you need to paint a car?
There are many size air compressor in the market. Sixty gallons size air compressor you need to paint a car. It’s good enough to paint a car. Of course, they are slightly larger compressors. But it is possible to find portable compressors or even vertical design models that take up little space. So if you work in a workshop you can store it in almost any space.
Can you paint a car with a small compressor?
Yes, you can paint a car with a small compressor!
What is a good size air compressor for spray painting?
Fifty gallons is a good size air compressor for spray painting. 1 Horsepower motor is good enough with paint sprayers rated for Six CPM and 30–40 PSI.
For remodeling, repair, or assembly work that requires the use of pneumatic tools, a compressor of higher power and that generates more airflow is necessary. Typically, a 3 horsepower compressor, 50 Liter tank, and 42 CFM airflow is sufficient to power pneumatic tools.
What is an air compressor?
This is a tool that is capable of generating energy by compressing air. In other words, it is a machine capable of using mechanical energy to convert it into pneumatic energy. This is achieved by air at very high pressure and then transferred to the tool to be operated by means of a hose.
Technical characteristics of an air compressor
Not all people know how to choose an air compressor, but the truth is very simple once you know the most important characteristics of each of them. This will allow you to choose the one that best suits the use you want to give it. For each type of work, the air compressor must meet some values or it will not be able to work.
The pressure at which the compressor works is measured in pounds * square inches, PSI or bars (1 BAR = 14.5 PSI). Most equipment does not need a pressure greater than 6 bar to function.
Tank or airflow capacity
By far this is the main feature that you should keep in mind. Because depending on the work you are going to do, you need certain airflow and pressure . Why? Simply because the tools that you are going to operate with the compressor may need up to 6.6 liters per minute. For example, paint guns and some drills.
But you should also take into account that if you will use several tools at the same time, it is necessary to add each output volume and add 25% of the total. This is done to encompass the transmission of pressure through the hose. For example, you need a compressor that can power a 350 l / min @ 90 PSI drill, a 350 l / min @ 90 PSI sander, and a 150 l / min @ 90 PSI blowgun. So your compressor should generate at least 812.5 l / min @ 90PSI. In this case, a 7.5 HP one would suffice.
This is also very important to consider. The power of a compressor can vary between 1 and 6 horsepower. Low HP compressors are used for simple, household things like inflating mattresses or tires. While the compressors with more horsepower are for industrial use.
To better understand this issue, more horsepower (HP or CV) generates more pressure. For example, for home use, a compressor with 1 HP is more than enough. But if you will carry out works that require between 350 or 400 liters of output, to choose a suitable air compressor this must be 2 HP. And if you want a compressor that generates at least 1000 liters per minute, the best is a 5 HP compressor.
Compressors can operate in two ways, electric or gasoline. For the first option, the compressor is normally connected to a power outlet or a battery. While gasoline compressors are an alternative if you work outdoors and there is no electricity supply nearby.
What are air compressors used for?
Air compressors can have many uses for both home and professional use. For example, they can be used to cut materials, drill holes, break rocks, screw, drill, sand, staple, rivet, etc. While at home they can be used to varnish, paint, clean, inflate car tires, inflate balls or mattresses, etc.
How to choose a paint air compressor
When choosing a suitable air compressor for paint jobs, you can go for a 2–horsepower, a 34–CFM, and at least a 24–liter air storage tank. Keep in mind that you must surely paint in various parts of the home, so it is best to buy a compressor that is transportable.
For more professional uses we should go to 3 CV. Although we should always look at the specifications of our painting tools.
How to choose an air compressor to inflate
If you want a compressor for things as basic as inflating balls, mattresses or tires. A 1 HP and 13 l / min will be enough to inflate almost anything.
These compressors are generally so small that they have the advantage of being portable. So you can usually take them in the car and they can be connected to the base of the cigar lighter.

How to choose an air compressor for cleaning
A compressor of 1 or a maximum of 2 horsepower will be perfect for this task. It is normal to use air compressors to maintain equipment such as computers since it allows the removal of residues from components without damaging them.
Of course, the airpower must be regulated so that it is sufficient to remove the residue but without mistreating the components.
