Types of spray guns: how to choose the right
Types of spray guns differ in their structure and work rules. They are also divided according to their power, there is a high-pressure spray gun, which is intended for large volumes of work. But you can make a spray gun from a spray can yourself, but you won’t do a lot of work.
It is about the main types of spray guns that we will talk today. Also, videos and photos will be presented to your attention that will help you make the right choice.

Airbrushes by type
These products are presented in retail chains. But in principle, they can also be made with their own hands, only components will need to be purchased anyway. There are some details that you simply cannot do. Consider what types of spray guns are.
And first of all:
High pressure spray gun | The industrial spray gun basically has exactly high pressure:

Low pressure spray gun | This type has advantages:
But there are also disadvantages:

What are manual spray guns intended for?
This is the cheapest airbrush, but its use is limited. In order to use water-based emulsion paint, as well as water-lime and water-chalk composition, the manual version is used. This airbrush is also intended for putty.
- It is cost-effective to use for a small amount of work, that is, for home use. To paint a huge area with the help of such an apparatus will definitely not succeed.
- It should be noted that a manual airbrush is also suitable for spraying shrubs and plants in the garden, and also for spraying cleaning solutions, disinfectants and fire retardants.
Attention: Observance of safety measures during the work with a spray gun is required, irrespective of the type of the carried out work.
What are the principles of choosing a manual spray gun
If you need to buy a hand-held sprayer, which is also of high quality, you should consider certain points, such as:
- For comfortable work, a lighter device with a suitable center of gravity is more acceptable;
- The spray nozzle of the apparatus must be multi-dimensional and have different nozzle diameters;
- For the main metal parts of the product requires significant wear resistance, as well as the possession of anti-corrosion properties.
Attention: It is false that any airbrush can create an impeccable coating quality. In fact, this issue is directly related to the nozzles, as well as to the diameter, needles, and considerable importance is given to the quality of the metal used to manufacture the product. Every detail in the spray gun is important.
Accordingly, when making a choice, you should pay attention to the tool, which is produced by well-known manufacturers. This is especially important if you have to work using expensive materials. The fee for a high-quality device is, of course, higher, but this is justified by the quality of work and a long service life.
Electric spray gun and how to choose it best
Modern electric spray guns have two technological features. You can become the owner of pneumatic or non-pneumatic. What is the difference between the two?
The first type is equipped with a small compressor that pumps air into a container containing paint. In the second type, the paint is pumped to the nozzle without mixing with air.
- In order for the quality of painting to be high, it is better to prefer models of the airbrush, which have a microcompressor built in. It will blow air and break the paint to a state of dust, which creates an even distribution over the surface. But for uncompressed models this is not typical. In them, the paint is broken to the state of small particles due to the pressure of the paint itself, which is created by the piston pump, and the design of the nozzle.
- Regarding visual inspection, the following can be said. Before purchasing a manual spray gun, you should find out what material it is made of. Manufacturers often use plastic for this purpose. Of course, such a device will not last long, since plastic parts do not last long and some solvents types of paints have a negative effect on them. The metal part in this embodiment should be at least a nozzle.
- The material for the manufacture of the spray gun is related to the type of paint with which it is permissible to work. The plastic model is perfect for use in a spray gun with water-based paint. However, in all respects the advantage will be with the universal device.
- In this regard, if the monetary issue is not acute, then the purchase of a universal spray gun will be a priority. High costs pay off with both quality of work and convenience. The instruction, which is attached to the spray gun, sets out in detail its purpose.
- In this option, you can also purchase a portable airbrush. Also, these models suggest a spray gun on the battery. So you can win in size.
Attention: When buying, you can not pay much attention to the power of the electric spray gun, because it is calculated for a specific design.
Pneumatic spray gun
Pneumatic spray gun - a device whose functioning occurs under the influence of compressible air, and its package includes a receiver and compressor. By means of a hose, the spray nozzle, that is, a gun with a paint tank, is combined with the compressor.
When connected to the mains, air is injected and the paint is broken into small particles. Then their exit follows a stream through a nozzle of the device.
The device of pneumatic spray guns allows a person to make a free choice of compressor and gun.
Devices are divided into three types, and they, in turn, differ in performance:
HP | They are devices with high working pressure (up to 6 bar) and low air consumption. Processing large areas is most effective for this type of spray gun. |
Hvlp | Represent a design with high technology. At the same time, there is an increase of up to 65% of carrying onto the treated surface of paints and varnishes. |
LVLP | This type of spray gun in terms of economy is the most profitable. Almost 80% of it transfers material. |
Caution: For all types of pneumatic devices, there are several ways to place the ink tank. It can occupy an upper or lower position, and it can also be with a forced supply of material that is transferred.
Manufacturers of spray guns have a range of nozzles for changing, varying in diameter, which are applied to materials with different grain sizes and viscosities.The price of such a kit is relatively large and for the most part specialists use it, since a professional approach is needed for work. The image displays the smallest set required to paint the car.
First of all, we need a spray gun, and then the following:
- Hose;
- Compressor;
- Oil and water separator;
- Adapter.
Consider what relates to the advantages and disadvantages of pneumatic spray guns
Advantages will be as follows:
- Painting is carried out with high quality;
- There are no restrictions in use either in the domestic plan or in the enterprise;
- Accessories can be selected independently;
- Performing a large amount of work in a short time is possible due to power and productivity;
- Absolutely all kinds of paints can be used.
The disadvantages are as follows:
- The weight of the device and its dimensions;
- Assembly must be carried out using a collapsible mechanism.
Differences between pneumatic spray gun and electric
For the sake of objectivity, it is worth noting that few of them have in common. They differ in principle of operation and in device. Pneumatic is a compressed air gun.
Of course, in order for it to work, a compressor with a receiver is required. The spray nozzle with a gun and a container is connected via a hose to a compressor, which is essentially a spray gun.
- Electricity is supplied to the compressor, with the help of which air is pumped and then enters the structure. The paint is broken from the supply of air under pressure into very small particles and is pushed through nozzles. All this forms a torch, as it is called.
- Decent money needs to be paid for the “compressor-airbrush” kit, in addition, so that it is correctly selected. On this basis, he finds for the most part professional use.
- The atomizer from electricity, or rather, with an electric motor, does not create compressed air and paint is sprayed only under the pressure that the built-in pump creates. Of course, the grinding of paint materials does not sufficiently occur, since there is no air flow.
- The quality of the coating made by this device will be inferior to the results that will be carried out even by inexpensive pneumatic analogues. However, this tool is compact in use, it is simple to maintain, it does not require additional equipment and means for air purification, and also the price is small. A household craftsman receives a serious relief of life if you have to carry out painting work at some periods.
Attention: According to most experts, electric paint sprayers are just household ones.
It will be important to note that there are such electric spray guns to which minicompressors are attached. Most likely, they are an intermediate option. They create a spray using compressed air. There is a clear relationship between the compressor and the productivity of the gun, which is placed in a separate casing.
- A special high-pressure hose (factory-made) creates a connection. If you pick up a pistol of such a "spaced apart" spray gun, then it is significantly lighter in comparison with a simple monoblock electric model and, moreover, there is no electric motor.
- The quality of painting using such an instance can be compared with traditional pneumatics. That's just the cost is far from cheap, starting with 500 conventional units. Great care is needed not to fall for the tricks of those who promote low-grade counterparts via television, far from being comparable in quality to a professional tool.
Before purchasing, you should devote enough time to study the description of the required tool.It’s not difficult to get an airbrush today, their price is different, the main thing is to take exactly what you need.
