Applications of Air Compressors in Airbrush.
Air compressor for airbrush working principle
When the compressed air generated by the air compressor is ejected through the air cap at the front of the airbrush, a low-pressure area lower than the atmospheric pressure is generated in front of the paint nozzle connected to it.
The pressure difference generated at the airbrush mouth will suck the paint out of the paint tank, and under the action of the high-speed injection of compressed air, it will be atomized into particles and sprayed on the surface of the object.

Compressed air pressure regulator
Air compressor produces pressurized air, the pressure of the compressed air depends on the size of the air compressor and the setting of the pressure regulator. Different coatings or paints have different densities and viscosities.
In order to perfectly spray each coating, you need to know how to adjust air compressor pressure regulator and the appropriate spraying pressure of the coating. For example, thin coatings are suitable for spraying with a pressure of 10-20PSI, and thick coatings are suitable for spraying with a pressure of 40-60PSI.
Water filter
Ambient air inevitably contains a lot of water vapor, unless it’s in the world’s driest desert, and compressed air contains more water vapor. Any water can cause great damage to the paint film just sprayed on. It will ruin the painting work.
Therefore, airbrush compressors are equipped with precision water filters to remove water vapor that may damage the paint. If possible, it is recommended to choose an airbrush compressor with air dryer or air receiver.
Air tanks
Air tanks, also called air receivers, are devices that temporarily store compressed air, but they are not limited to this. They are also a good helper for cooling and drying compressed air. Air tanks can also make compressed air smoother, reduce airflow pulses, protect pneumatic tools, reduce downtime, etc. For long-term use or busy working environments, airbrush compressors with air tanks are a good solution.

How to choose the right air compressor for airbrush?
There are several critical things need to know before choosing the right air compressor for airbrush.
Oil vs oil-free air compressor: In the high-quality spraying industry, impure gases often result in inferior coatings, while oil-free compressed air helps ensure paint adhesion, avoids bubbling, eliminates obstacles in paint adhesion, and makes the coating more uniform and smooth, thereby improving the beauty and durability of the spray paint.
Therefore, oil-free air compressors are the first choice. However, if it can be ensured that the compressed air produced by the oil-lubricated air compressor has been fully filtered to remove the oil or the remaining oil particles cannot affect the spray paint, the oil-lubricated air compressor will be a more economical solution.
Air compressor size chart: PSI (pounds per square inch) and CFM (cubic feet per minute) are two important parameters that determine whether the airbrush can work properly. Before choosing the right air compressor for airbrush, first need to determine how many airbrushes need to be driven. The airbrush compressor can drive multiple airbrushes at the same time as long as the air flow and air pressure generated are sufficient. If you only need to work for one airbrush, you only need to meet its maximum working pressure and air flow.
Air compressor duty cycle: Some air compressors cannot run for a long time. Due to design reasons or heat dissipation reasons, they will accumulate a lot of heat during work and cannot dissipate heat in time, so they need to stop for a period of time to allow the machine to cool to normal working temperature. This period of time is called the duty cycle of the air compressor. For example, a 50% duty cycle means that the air compressor needs to stop and rest for 30 minutes after working for half an hour in an hour, while a 100% duty cycle means that the air compressor can work continuously!
Air compressor noise: Although air compressor noise does not directly affect the quality and progress of painting work, it has a great impact on the staff. Excessive noise can make people depressed and irritable, which in turn affects the quality of work. If you have a low tolerance for noise or need to work at home, a low-noise compressor is a more comfortable choice.
Types of air compressor for airbrush
Reciprocating piston compressor
Reciprocating piston air compressors compress air by reciprocating pistons in cylinders. They can be single-stage or multi-stage, with the difference being the number of cylinders. Piston air compressors may be common items in the corner of the garage, hardware store, or home basement.
The advantages are affordable prices and higher power for the same size, so it can be made in a smaller size mini airbrush compressor; the disadvantages are higher operating costs and pulses in the airflow that may affect the quality of the paint.
Diaphragm compressor
Diaphragm compressors use a curved diaphragm that moves back and forth in a closed chamber to achieve compression. This design is a change from the concept of a reciprocating piston. The movement of the connecting rod under the diaphragm causes the bending, and only a short stroke is required to achieve a similar effect to a reciprocating compressor. The disadvantage is also the lack of stable airflow, but this can be solved by configuring an air receiver.
Portable air compressor
For situations where the work location is not fixed or is far from the available power grid, an oil-free portable compressor can be selected. These compressors are usually equipped with trailers or tires, and may be powered by batteries or fossil fuels such as diesel, which can be moved at will and work freely in any location.
Oil-free air compressors
There are many types of oil-free air compressors, including oil-free screw compressors such as oil-free water-lubricated screw compressors and oil-free dry screw compressors, rotary vane compressors such as oil-free centrifugal compressors, and oil-free scroll compressors, which are famous for their quietness.
These oil-free air compressors have their own characteristics, but one thing they have in common is that they are relatively expensive to purchase and are suitable for applications that require higher work quality.
Clean Air 100% Oil-Free: Oil-free type compressors can supply clean air.
Kotech compressor product quality fully reflects the most modern technology, its design and manufacturing processes are executed in accordance with the requirements of ISO9001 standard.

Industrial air compressors
If you need to use an airbrush with a larger nozzle or higher pressure, you need an industrial compressor that can produce more air flow and higher air pressure. The disadvantage of an industrial air compressor is that it is noisy because it has to work harder to compress more air.

Whether in the fields of construction, automobile manufacturing, furniture making, etc., airbrushes play an important role.
However, airbrushes need pressurized air to work. Therefore, the choice of air source for airbrushes is very important.
If the air compressor is unqualified and the compressed air supply is insufficient, the airbrush will not be able to perform its performance. Kotech is a professional airbrush compressor manufacturer with more than ten years of experience.
Choosing us, you will get market-leading technology, guaranteed air quality, and our professional care maintenance agreements and performance services.
