WHAT AIRBRUSH COMPRESSOR TO BUY?
What airbrush compressor to buy?Here is a summary .
Nowadays, you can find airbrush compressors of many types, but to know exactly which one is right for you, you have to ask yourself how long you will be working continuously.
To do so, look at these two points that we highlight so that you can leave doubts:
- The bigger the surface to work with the most powerful airbrush has to be your airbrush compressor.
– Compressor size ratio by aerographic discipline:
- Nails = Micro
- Temporary Tattoo = Micro
- Facial Makeup = Micro
- Modeling = Medium
- Helmets = Medium
- RC = Medium
- Pastry = Medium
- Illustration = Medium
- Textile = Medium
- Automotive = Large
- Body Paint = Large
- How more pieces in a row you want to work with the most powerful airbrush has to be your airbrush compressor. EXAMPLE: A temporary tattoo can be painted with a small micro airbrush compressor but if you want to make tattoos to the whole class of a school you will need a large-sized compressor.
- Interesting data on airbrush compressors
- Air boiler: The air boilers serve to charge air before starting to airbrush and feed directly from there, they are like a reserve of air that will provide the air flow without cuts or drops of flow. They serve so that the engine can rest and do not overheat so much, although in practice, the boilers of the airbrush compressors are so small that the air load is almost constant.
- Air flow regulation: Most compressors have a pressure gauge through which to adjust the air pressure, for an airbrush you have to regulate it at 2 -2.5 bar pressure. If you do not have a conventional manometer, you will probably have a thread that will allow you to increase or decrease the air flow.
- Maintenance: Oil-free airbrush compressors (almost all) do not need any maintenance other than controlling their temperature. If you see that it is hot let it rest a few minutes. As they do not carry oil they do not dissipate the heat so effectively and therefore tend to present greater warming than those that do work with oil. They are also much cheaper.
- Power: It is the brute force that has a compressor at the time of supplying air flow. The more Cv your airbrush compressor has, the more airflow you can supply and the more relaxed you will be at the time of non-intensive airbrushing jobs. Large-sized compressors can supply air even for 2 airbrushes at a time.
- Air consumption of an airbrush (it will depend on its nozzle / needle passage) = 10L / Min approximately
- Air flow of the MICRO Compressors = 10-15 L / Min
- Air flow of Compressors MEDIUM = 15-25 L / Min
- Air flow of BIG Compressors = 25-40 L / Min
TYPES OF COMPRESSORS FOR AIRBRUSHING
There are many different makes and models of compressors, and knowing for sure which one to choose in the face of a great variety and price is not an easy task.
For me to assist you in choosing the best equipment for you to perform your paintings and have no problems I will present below some models that I think important you know and who knows does not meet your type of work.
PORTABLE COMPRESSOR FOR AIRBRUSHING
If you intend to airbrush A4 sheets, plastimodelism, make-up or even paint sculptures, this type of compressor may be an option that you should take into account.
In addition to too small allowing you to have more space in your workplace it has a pressure between 15 ~ 25 psi which can be very little if you need to do a very large job.
According to the manufacturer the compressor can work at a constant pressure of 35 psi however due to being much above what the compressor can work, this pressure can suffer much according to the execution.
The air flow being 10.5 liters per minute is a good choice if you want to do airbrushing and small objects that do not require constant painting.
The great advantage of this model is that when it reaches 25 psi the compressor automatically shuts off the cooling drive, all because it does not have an air storage system.
So the compressor stays at a safe temperature so there is no overheating.
For a slightly larger work, I do not recommend this type of compressor because it does not have a very large flow of air and can run the risk of damage to the equipment.
MINI COMPRESSOR FOR AIRBRUSHING
If you are looking to airbrush on bikes and even on cars here is one option that you should take into consideration.
This equipment, besides being very resistant, has a very practical size, while being one of the portable compressors you will see in this article.
This compressor is currently widely used in airbrushing and can also be used for other purposes such as:
- Realization of Plastimodelism;
- Realization of Paintings in Sculptures;
- Realization of Cake Customization;
- And much more.
For this compressor model because it does not have a very powerful motor being 1 / 6HP and with a working pressure rotating around 30 to 40 psi, you will not be able to use a paint gun, but its strength allows you to work for hours without stopping with an airbrush.
So if you want to make paintings on canvas this compressor will suit you very well as long as you use an airbrush to perform your painting, so you will be able to extract the maximum of the compressor to carry out your work without running the risk of damage to the equipment.
But this compressor I would no longer recommend for a wall painting that would require a large amount of paint to be sprayed onto the surface unless you use it to do just a few details.
MOTO COMPRESSOR FOR AIRBRUSHING
To perform an automotive painting we do not always need huge compressors that contain a large air storage, there are some specifications that we have to take into account when choosing a good compressor that I will explain below.
What you need to understand is that with the wide variety of equipment we have on the market there are compressors known as motorbike compressor that can perform a painting in a car quietly.
The name bike compressor is due to its constant noise whenever it is triggered, many artists do not indicate it due to its constant noise that can bother sometimes.
Apart from this detail, we can use a small compressor to perform a quiet automotive paint job. In particular, I currently use a model like this to perform my gear on the airbrush.
Motorcycle compressors are widely used by artists who perform wall work due to ease of handling and also the power they can get to use with a paint gun.
But if you are wondering if there is a compressor like this small and quiet, yes there is however the big difference is its value that may be double the price compared to the motorcycle compressor.
This detail will depend on the type of work you will perform and especially on the power you will need to perform your paintings, the power will explain in more detail below.
DIRECT AIR COMPRESSOR
There is another type of compressor very similar to the first models that I mentioned but with a different purpose that are known as typhoon.
This compressor model are of a larger size, as the models compressor motor compressors direct air work very well with paint guns but for airbrushing there is a small problem that you should take into consideration.
These compressors do not have a pressure regulator like the previous models presented, due to their high air flow you will have difficulties working on airbrushing where precision is more important and needs to be constantly controlled.
There is the possibility of adjusting the regulator, however the investment value would already be a higher value and if you compare in the market you would already have other options that will give you a product ready to use.
This compressor model is very similar to motorcycle compressors because it allows you to work with paint spray guns, but the pistols that work very well are the direct air guns that I will address in other content.
Now let’s understand how you do to know which motorcycle is right for you, so keep reading this content and find out now.
HOW TO KNOW WHICH COMPRESSOR IS IDEAL FOR ME?
In order to find out which compressor we will need to make our paintings, whether in the airbrush or even in the painting of a car, there are some factors that we will need to analyze in order to know what it will be necessary to buy.
For our first analysis we will need to think of some details being:
- What will be the use of the Compressor;
- What value do we have to make the investment?
The type of use to be made with the compressor will significantly influence the value of the compressor to be purchased, for example.
If I only perform airbrushing where I will use an airbrush that releases a fraction of air compared to a spray gun, I will not need such a powerful compressor.
The equipment that you will use with the compressor will significantly influence the model and power of your compressor.
If you need a powerful compressor however you do not have enough money to carry out the investment you will have to do a good analysis to know which compressor to use to perform certain work.
With these two very clear information we will need to analyze some technical aspects to make such a choice.
For this we will need the following information:
- How many PCM or Cubic feet per Minute will be needed;
- Reservoir capacity;
- How many PSI or Pounds per Inch Square Gauge will be required;
Let us better understand about why PCM is important at the time you perform the purchase of your compressor as the other aspects that are relative to your work.
How many cubic feet per minute will it take?
Whenever we are going to search for a new compressor we need to understand how many PCM this compressor can generate us, allowing us to perform the accounts to perform our jobs easily.
This is very important because it is the filling of our compressor, so if our compressor does a slow filling it can cause us not to use that much desired pistol.
Every manufacturer informs about the production of air that the compressor performs, but this measure is not 100%, is something more theoretical than technical.
Because these compressors are for lighter work, to fill the storage causes that in this part has a loss of air generated, and from one manufacturer to another this value can change.
What I advise is that you put a 35% loss on the value informed by the manufacturer that when performing your accounts with the equipment that you will use, so you can buy the correct equipment for your type of work.
For you to understand I will give you a very simple and practical example.
Imagine that you will need to use a hvlp paint spray gun with the 1.4 mm nozzle where it needs 10 PCM to perform very well.
As an example imagine that I go to use in a compressor that has 8.3 PCM, do you know what that means?
That will not be possible, the compressor produces much less air than I’ll need it without counting the loss we have in the process.
Causing at the time of painting the pressure of my gun lower interfering in the painting completely.
Not to mention that the compressor will not stop filling and may even damage due to the engine constantly working.
To work with this pistol will require a compressor with 10 PCM minimum to be able to use this pistol without losing quality at the time of painting.
This is a simple example of how you get the idea of what to take into account when it comes to calculating, so it gets easier and you do not make a bad investment.
IS THE RESERVOIR CAPACITY IMPORTANT?
The capacity of the reservoir can, as it can not be a deciding factor when you choose a compressor.
If you plan to use a compressor in a workshop, storage is already a decisive factor when it comes to making the investment.
In airbrushing generally 25 Liters is enough for you to perform optimum jobs and be able to use a pistol to carry out the varnishing of your works.
The main factor is the type of equipment you will be using, if you are going to use equipment that requires constant airflow, I recommend that you look for compressors with a greater amount of storage.
Now if you will only use a paint spray gun and an airbrush, 25 liters will suffice and will meet your needs.
But this detail is at your discretion to choose based on the equipment that you will use.
PSI INFLUENCE IN THE CHOICE OF MY COMPRESSOR?
Unlike the capacity of the compressor that does not have as much influence in choosing the PSI yes will have a certain influence, however everything will depend on the equipment that you will need.
To assist in your decision imagine that you will use a sander with your compressor, which usually consumes 90 lbs / PSI.
If you have a compressor that produces at most 80 PSI, you would have a problem due to the amount of pressure required that your compressor would not deliver.
As a result of you having to make a new investment in other equipment to meet this need, of course this is a fictional example that I give you to understand how important it is for everything on paper.
Now you understand that to realize the investment in a compressor you first need to know what you are really going to do with it so it is easier to perform all these calculations.
Besides the thousands of marks that exist my goal here is to present the technical part that few people comment on when it comes to helping what is good and what is bad.
Notice how very good a compressor is and what a bad compressor is.
