The modern market of paint-spraying equipment is quite diverse, which is a consequence of the presence of different types of devices. Among these, we can note air and airless, which have differences that can make changes in the workflow. The second type is no less effective, and it requires more detailed consideration.
How does it differ from the air one?
Based on the name, you can already understand that airless models do not require such a device as a compressor. It is he who creates the air pressure, which sprays the paint. In the case of an airless tool, the basis of the work is the principle of dispersion, that is, the crushing of the material and its delivery to the surface to be processed.
In addition to this difference, there are others. First of all, we can say about the application of paint itself. It is more effective, since the disadvantage of air models is the waste of material in the air when using paint and varnish materials. This percentage is much lower among airless units, since the working mixture simply has nowhere to disappear, because it gets directly to the surface.
This method has both advantages and disadvantages. The advantages include high efficiency and quality of spraying, which is used in industry and construction. Among the disadvantages, the main one is excessive straightforwardness. Due to too high pressure, the paint is released so quickly that it is better to process simple parts of the usual shape, without any bends and other design features.
And also the setting of the airless tool itself requires more precise adjustment, since the material is applied in a smooth jet of high force. It is impossible not to say about the features of cleaning. This process should be given special attention, because ignoring it reduces the efficiency of the nozzle much faster than with air spray guns.
Listing the differences between these types of sprayers, we can say that airless ones are more used not in everyday life, but in industry, for example, in car dealerships, shipbuilding and other areas.
This field of application is expressed by the versatility of airless spray guns, because they can handle a large number of materials, regardless of their condition.
Because of this, such units are used in the furniture industry, where insufficient wood processing will not be a serious obstacle to painting. This can also include the use of airless spray guns on the railway. It is roughing that makes this type the most versatile, although more demanding to use.
Operating principle and device
The main difference in the design of airless models, as mentioned earlier, is the absence of a compressor. To the spray gun, or rather, its gun, a hose is connected, which feeds the paint through the nozzle. It has a small size, so that the torch has clear borders and applies paint materials as tightly as possible, thereby achieving high efficiency.
It is worth mentioning the presence of a special safety system, the main purpose of which is to protect the user from high pressure of the tool, while not interfering with the operation in any way.
The design also provides for the installation of a filter. It allows you to perform painting actions even in dusty rooms, if you do not have time for cleaning. Of course, it is better to initially work in a suitable place, but there is such a possibility of instant operation without loss of quality.
The paint supply to the nozzle is carried out through an electric motor, which can be connected to different types of drives.
In general, the principle of operation does not differ from the air models, with the exception of these features. Through the actions of the mechanisms, the coloring substances enter the nozzle and are distributed over the surface.
It is important to add that the main paint materials that can be used are alkyd, flame retardant, latex, textured and epoxy mixtures.
Kinds
In total, there are three types of airless spray guns, and each requires special attention to understand the operation and scope of application based on technical features.
Electric
This type of drive is powered from the mains system via a wire. This should be taken into account in order to ensure maximum safety and operability of the tool. Using this type of models, it is always necessary to have a power source nearby, which is best paint sprayer ceiling shown when operating in domestic conditions. If you pay attention to electric spray guns, you can understand that they do not have as much power as the other two types of units.
This is due to the fact that the main advantages and features of operation are convenience and compactness. Optimal characteristics for performing an average volume of painting, small dimensions and weight, easy transportation – all this can be attributed to the main advantages of battery units.
We must not forget that working from electricity has its own peculiarity, since this type of device is forbidden to use in fire-hazardous and too humid places. There may be a short circuit or an oxidized mechanism.
A type of spray gun that runs on the most familiar fuel-gasoline. The main advantage can be called independent operation. You will not need to worry about having a nearby source of electricity. Just fill in the fuel, and use the tool.
Gasoline models have good power, due to which they are most often used in industrial work. High efficiency can be attributed to the pros, but there are also disadvantages.
First of all, this is the exhaust from the fuel. They are harmful to inhale and, most importantly, require special operating conditions. It is very important to take care in advance that the working room is ventilated.
Therefore, gasoline airless models are used in open areas, such as construction sites, where the presence of exhaust does not have serious consequences. Power also affects the transport capacity, which is a disadvantage in combination with considerable dimensions.
Pneumatic
The most efficient type of drive, as it allows you to work with large area materials. The basis of the work is a pneumatic installation designed specifically for industrial scale.
As a rule, this type of spray guns is used in car service stations, car factories, in shipbuilding and other industries where the time to complete the task is very important. Naturally, pneumatic models have the highest price, but if you know how you will use such a unit and can realize its power, then it will pay for itself in a fairly short time.
How to choose?
First of all, decide on the type of device. By evaluating the advantages and disadvantages, as well as the design and operation features, you can choose the appropriate model based on the tasks and scope of work.
Pay attention to the individual parts of the spray gun, for example, the diameter of the nozzle. This characteristic is responsible for ensuring that the spray gun can release as much material as possible.
This increases the consumption of the emulsion, and the work can be done faster. The usual size, which forms a torch diameter of up to 80 cm, is enough to perform a wide range of tasks.
Do not forget about the indicator of the use of the maximum allowable viscosity. It should be 50-80 Din, so that you can use the paint of different consistency and independently adjust its condition by adding the necessary amount of solvent.
Before choosing, it will be useful to learn more about the design, or rather, about the presence of various nozzles on the nozzle, about the handle and its structure. Among the technical characteristics, we can note the importance of the noise level and power, because these two parameters determine the efficiency and convenience of the equipment.
No less important is the selection of equipment from a particular manufacturer. In the modern market, there are a large number of companies that are ready to provide their products to the consumer.
The possibility of a wide choice in this case is crucial, since you can proceed from your budget, specific preferences, and compare the capabilities of the model with your tasks.
Information about good and trusted manufacturers can significantly help with the purchase. You can make a small rating, which will include well-known companies with a good assortment.
Graco is a company that specializes in hand-painted equipment. Among the advantages can be noted a wide range, which is built on the model line.
That is, one unit has several variations, which differ in their characteristics and configuration. This variety allows you to choose a spray gun based on the budget.
Bosch is a well-known company that produces various types of power tools.
A sufficient number of the assortment in the most diverse design allows the consumer to choose equipment of different levels and fields of application. 
Good quality and average price have long been appreciated by customers, so Bosch models are easy to buy in Russia. This also applies to spare parts that can be purchased separately.
Wagner is a German manufacturer that is primarily known for its automated systems that are used in large-scale industry. Wagner pneumatic models are made with the use of modern technologies, which ensures high quality and efficiency of various works. Of course, these systems have a high price, but they are designed for mass and extensive use, which will be able to recoup the cost of equipment in the future.
"Zubr" is a domestic manufacturer of inexpensive equipment, among which there are also units for painting surfaces. The model range of the low and medium price segment, expressed in the optimal ratio of quality and cost, is best suited for domestic use.
Simple operation, reliable design and the possibility of good feedback makes the Bison paint sprayers one of the most preferred for their price. And it is also worth noting the low cost of spare parts and other components, which reduces the cost of operation.
