It may be clear that without air Airbrushing source / compressor is not possible. It takes a certain pressure to spray and airbrush any she has its own characteristics and requirements. It is therefore important to choose the right compressor is why I decided to have a nice piece of writing about so you know what you are buying. Your choice for a compressor can only be made if you know which airbrush you want to go and kind of work you want to do.
First, I will mention a few characteristics that affect when choosing an air compressor.
- Bar / PSI
PSI / BAR / CFM
The lcuhtdruk is one of the important points. On most compressors will the pressure indicated by a “Gauge” this is the amount of pressure read. It is often mounted a controller so you can set the pressure.
The pressure word indicated in PSI , and it stands for “pounds per square inch”, and the word indicated by BAR . On the image you can see that the red indicates the amount of PSI and in black the number BAR to read.To spray or airbrush you need a constant flow of air with a certain pressure. Each type of paint spray paint, and she has own amount of pressure CFM (cubice feet per minute) required to function properly. So look at the properties of a compressor What is the net air output and the maximum pressure.
A thinner-based paint / paint requires less pressure than water-based paint.
Thin paint (low visositeit) 10-20 PSI (Golden Airbrush Colors, Schmincke, House of Kolor)
Thick paint (high visositeit) 40-60 PSI (Createx, Auto-Air, dyes)
About varnish and paint later!
There are many experienced and less experienced artists who have no money for proper compressor and build one yourself from an old refrigerator for example. This is not a bad option!But make sure that you have a sound pressure regulator that can deliver a constant pressure.
A compressor with a 75 decibel can make life miserable! Unless this is far away. Choose a compressor with an acceptable decibel. The rule is the fewer decibels more expensive compressor. A noisy compressor of the construction is cheap and fine to use for most airbrushes but makes a lot of noise. It is very silly if you eg mixxen of paint scares you rot because the compressor starts. Whether you’re just busy with the final details and hits your hand away because you are frightened. An important point is that the compressor is silent and I mean a decibel of ± 40 and the types that are not “Pssssss” or click sounds are slightly more expensive. You can also opt for a cheap compressor and money to invest in a soundproof box where you insert the compressor. If you choose this option, please remember that you ensures proper airflow to cool the compressor.
Each type compressor generates water vapor and water! Water can damage your paint and tools.It is therefore recommended to use a filter or to have a water separator. These separators filter the water from the air so you can airbrush or spray carefree. With some compressors a water separator is already assembled and some you will have to buy it separately. you can buy cheap good water separator. Also, there are separators for sale which have a pressure gauge and regulator. The standard moisture separator an inexpensive compressor often does not meet the airbrush / spray requirements!
If you always ask a compressor used buy here if the tank is oiled. If this is the case then you need an oil filter. If you do not then it eventually oil will come through your hose and airbrush and land on your artwork. They finish to the tank to prevent corrosion and to lubricate the tool. An oil filter looks almost the same as in a water separator. Also, there can be obtained, such as double combinations of a moisture and oil filter next to each other.
Example moisture and oil separator.
The endurance of compressors is different. It is therefore advisable for there to look at when purchasing. Some namely have a period of rest / cooling-off period required for half an hour to work after 30 minutes (50%). There are compressors that can run continuously. Most do not even know how long the compressor must rotate and look totally not making the compressor faster piece will go and in some cases can even burn !. It is usually to be found in the properties or user what may be the constant operating pressure. If this is not the case the manufacturer send an email or call it as a compressor you usually buy for a long time.
Some types that you will encounter on the market :
- Piston compressors
- Screw compressors
- portable compressors
- Airbrush compressors
The piston compressors are the workhorses that you’re probably most familiar with. You see them everywhere namely: stores, garages, basements. Often they are quite cheap but also go the most part and repair costs are very expensive! If you want to use a lot of air, it is advisable to look at a different type so that you can enjoy for a long time by air. These types are cooled with oil and are not really suitable to transport. The compressor should not you not tilt too much because of the oil in the reservoir.
Example reciprocating compressor
Screw compressors are often used for industrial purposes and therefore need 380Volt. They are quite expensive but often do not need a rest. A screw compressor has two screw profiles, and these are cooled with water or oil. Some types have an air reservoir. The decibel can vary.
Are often oil-free and therefore need a rest because oil normally ensures the cooling.
There are also portable which have oil-cooled like this type:
Again, you have a lot verschillnde variants. For example, the diaphragm compressor, it is suitable for small work (nail art, model making, face-art, airbrush tattoos) Nozzle great t / m 0.3 mm. The disadvantage of a Diaphragm is that they are prone to condensation in the air hose, this is a natural phenomenon and depends on season and working environment. If you suffer from it use an in-line filter or a water filter under your airbrush. For custom paint, murals, body paint etc is the membrane compressor not the right choice because it often requires a rest period because this type is not cooled with oil. Also, they do not have any storage tank.
Example diaphragm compressor
For larger airbrush work is a whistler silent compressor is a must. They have a tank capacity of at least 1 liter, automatic stop and often have a noise level of ± 40 decibels. Often they have a good moisture separator so you always have clean air. Note that, especially at the cost of the engine is sealed making repairs become impossible! This varies by brand and type and let you inform about it well. Most vendors are beginning fact not!
Example silent airbrush compressor
What is important in a row
- pressure regulator
- moisture separator
- Sufficient air net revenue
- repair options
- Oil Filter (if you oil tank)
- Consider the vision / number of decibels
My advice is to have a battle to buy larger compressor than you actually need think because when you first start airbushen or syringes than you want to fix a few things to try, and if you buy an airbrush in the future that requires more air than the compressor may perhaps not. Or maybe you want a once another try paint better with a syringe hogo pressure of eg 50 to 60 PSI.
Make informed when purchasing an airbrush compressor, it can save you a lot of trouble and money because cheap is a good compressor. Best Air Compressor Guide
