Which is the best spray gun to choose. How to choose a spray gun for painting a car in a garage? What is a spray gun

The principle of operation of a spray gun of any model consists in creating an aerosol from liquid paint and applying it to the surface. In coloring devices there is a nozzle (spray head with a nozzle, nozzle), a trigger, control valves for supplying paint and air. Some models are equipped with a pressure gauge to adjust the pressure.

Allows you to quickly and evenly apply the dye to complex surfaces - embossed, openwork, large area... Thanks to the thin layer of paint, material consumption and drying time are reduced.

How to choose a spray gun

Manufacturers produce pistols that differ:

• by power;
• method of management;
• the volume of the fluid tank.

Power

Low-power ones are suitable for home use. They are cheap, have a low paint supply power in the range of 0.2-0.5 kW. Consumption is about 0.5 kg / hour. This is sufficient for amateur use. For professional use, choose powerful models up to 1200 kW. These tools work faster, are heavier, and are made of metal.

The speed of drawing paint from the tank fits into the passport of the spray gun. At the exit, this figure is about 35% lower.

Control method

Manufacturers produce sprayers of two main types: electric and. The first type works by means of a piston driven by a current, the second - due to low pressure.

Each species has different:

• power;
• the material from which the body is made;
• the volume of the container for paint.

Container for coloring composition

The volume of the liquid reservoir is selected depending on the work performed. A large tank is needed to whitewash the ceiling, but it will become a hindrance for working with small parts. Plastic containers are light and transparent. The operator can see the amount of paint in the canister. But plastic is easily damaged by mechanical and chemical stress. After work, the tank is washed with solvents or acetone. Frequent exposure to the reagent has a bad effect on the surface of the plastic, and over time it becomes unusable.

Metal tanks are more resistant to damage of various kinds, they are washed chemical means without fear. Such containers are more durable. But they are heavy and opaque.

There are models with an upper and lower colorant container on sale. In the overhead position, the paint flows into the gun by gravity. At the bottom, it falls into the spray gun under the influence of the pressure created during the operation of the tool.

Floor and hand sprayers

Both types of spray guns are available as floor-standing and hand-held. Floor standing models are equipped with a large paint tank. For convenient movement, manufacturers install wheels and carrying handles on the body.

Subtleties of choice

When choosing a spray gun, pay attention to the material of the body and working elements. The body is made of special impact-resistant plastic or metal. The working parts in the spray gun must be metal. For the main nodes use:

• brass;
• stainless steel;
• aluminum.

For electrical models, the power source is important. Sprayers operate from a regular 220 V mains or from a battery. In the second option, the battery should work for at least 1 hour without recharging.

The diameter of the nozzle depends on the job being done. There are several nozzles included with the spray gun. They spray paint in different particle sizes and diameters. Some models are equipped with a filter to retain solid fragments. This protects the nozzle from clogging, which extends tool life.

Technical data of spray guns

1. Performance and generated pressure... These indicators affect the speed of work and its quality.
2. Nozzle diameter and number of replacement nozzles included. The more nozzles you add, the more options you have for using the gun.
3. Weight and vibration level. The lower these indicators for the manual model, the longer and more productive the operator works. For a floor sprayer, these indicators are secondary.
4. Additional options. Adjustment of pressure and spray method allows the sprayer to be used with maximum effect.
5. Brand. How better known manufacturer, the more you have to pay for the tool.

Best Electric Spray Gun

Electric sprayers consist of:

• engine (power plant);
• hulls;
• pump;
• liquid tank;
• several attachments of various configurations.

The difference between electric guns and pneumatic models is the feeding coloring material without air. The ejection of the composition occurs due to the translational movement of the piston. An electromagnetic cushion moves the piston forward and a front spring returns it to its original position. At the same time, a slight vacuum is created in the body, and the paint is drawn from the tank into the working container. On the reverse movement, the piston squeezes the paint, and it is ejected under pressure from the housing in an atomized form.

Pistols work with compounds of different densities. The passport indicates the type of paint for this model. In order not to damage the tool, you cannot use it for other types of dye.

Electrical consoles are air and airless. The first one distributes the composition in an even layer, but creates a cloud of paint around the operator. When using such models, large losses of material occur, and enhanced protection of the eyes and respiratory tract of the worker is required. The second type of electric gun works at a distance from the object. It has little paint loss, no cloud of suspended dye.

The quality of the tool is influenced by the correct choice of nozzle and working pressure. At high pressure, the dye layer will be uneven and material consumption will increase.

Manufacturers have created an intermediate model - an electric spray gun with a compressor. It creates the required low pressure and the quality of the staining is improved.

When choosing an electric spray gun, pay attention to automatic shutdown in case of overloads.

Specifications

• voltage - 220 V;
• tank volume - 0.5-2.2 liters;
• nozzle diameter 1.2-1.7 mm;
• working pressure - 150-200 atm;
• power up to 625 W;
• weight without coloring composition - 1.4-2.5 kg.

pros

• small size;
• cheap;
• mobile;
• easy to store and maintain;
• lungs;
• do not require special training for work;
• constant pressure does not require adjustment;
• large tank capacity;
• high speed of application of the composition;
• high quality staining;
• use material sparingly.

The ease of use and affordability of the electric spray gun makes it suitable for use without special training. The tool is universal and is used for painting cars, spraying liquid formulations on plants, applying disinfectants and detergents. It is used for applying primers, enamels, drying oils, varnishes, paints.

Minuses

• low power;
• vibrate during operation;
• create a lot of noise;
• the place of work is limited by the length of the cord;
• you cannot grind the coloring composition to a very fine state, since there is no pressure;
• when the container for liquid is in the upper position, there is a possibility of the composition leaking onto the body, which leads to a breakdown of the instrument.

Domestic models have shown themselves well in work Bison(reliability), Caliber(staining quality). German pistol earned positive reviews Bosch(functional), for rare use, purchase a model TM BORT.

Best pneumatic spray gun

The pneumatic spray gun operates on compressed air. A compressor is required for painting and auxiliary equipment... The gun is connected to the compressor using a hose through which compressed air is supplied to the tool. It sprays the liquid to the state of an aerosol, it is fed into the nozzle, through the nozzle it enters the outside and is sprayed onto the surface. Some models are equipped with a pressure regulator that allows you to select the density and particle size.

There are 3 options for pneumatic spray guns on the market.

1. HP. They work together with a unit that creates a pressure of 3-7 atm. In this case, the paint layer can be applied unevenly, there is a large loss of the coloring composition during the process (50%). It is used in areas where it is important to quickly apply paint to the surface: ceilings, walls, production facilities, building facades, fences.
2. HVLP. Instrument with high air volume / low pressure combination. A spray gun of this category is not sensitive to the power of the compressor, it works at a pressure in the range of 2-4.5 atm. The tool creates a "soft" torch. It qualitatively applies the composition to the work surface, economically consumes raw materials. It is used for high-quality paint application on embossed and small parts.
3. LVLP. Literal translation of the name of the pistol "compressed air / low pressure". Works with a compressor that creates a pressure of up to 1.5 atm. This is a professional tool that provides high-quality and fast application of the composition. Material loss is up to 5%. Used to work with expensive paints.

Professional and household spray guns brought surface painting to new level... After applying the composition with a spray gun, there are no streaks, the layer is even, and the consumption of material is reduced. Expensive tools (airless) are more productive, but they are better for rent.

A spray gun or spray bottle is one of the most important tools you need to paint a car. Its peculiarity is to spray the dye with an airborne method using compressed air pressure. On the modern market there is a wide variety of such tools, and many find it difficult to decide on the choice of a suitable option. How to choose a spray gun for painting a car among the models presented in stores, and what characteristics should you pay attention to?

Sprayers for paint, as they are known, were invented at the very beginning of the last century. But now there are many designs of these devices. Different types of paint sprayers are caused by different methods of working with them. Despite the external resemblance to pneumatic spray guns, spray guns are seriously different - they have a different structure of air heads, as well as different designs of channels for air supply.

The peculiarities of each specific type of sprayer significantly affect the comfort during operation, as well as when carrying out painting work.

How often will the spray gun be used in the work? If you need it to paint one car or several, then for such volumes there is no need to purchase an expensive professional device. But at the same time, you still need a gun for painting, which will be able to cope well with its tasks. For such purposes, suitable inexpensive devices type HVLP with the required characteristics.

In order to choose a tool, you should also determine the tasks that you will have to solve. There are sprayers where different systems spraying. To make the right choice, you should get acquainted with the theory and understand the whole variety of tools and their characteristics. This is the only way to make the right and competent choice.

Any device is suitable for painting a car, but the higher the quality of the device, the better the final result of the coating will be. For beginners, experts recommend purchasing the most budgetary, but high-quality solution, and then, when experience is gained, you can buy a more professional spray gun.

How many nozzles should you have?

Experts recommend having multiple nozzles for different tasks and for working with different materials. There are models designed only for varnish or only for paint, for primer. If funds allow, it is worth purchasing a spray gun for each material and for each task. In this case, you do not have to solve the problem of getting paint into the varnish, which was sprayed shortly before it.

Naturally, you should not buy three devices - there are specialists who use one gun, the nozzle is 1.6, and any materials are applied with this tool. However, it will take a long time to clean the gun.

Compressor

The atomizer is recommended to be selected according to the characteristics of the compressor. It is possible in another way - after purchasing a pistol, choose a compressor for it. The compressor must deliver the required volume under pressure at all times during the operation with the spray gun.

The main rule that affects the choice of a spray gun for painting a car is that the compressor must produce a volume of 1.5 times more than is required for normal work gun under pressure.

If the compressor capacity is insufficient, good atomization will not work. The compressor must deliver characteristics above the required pressure, but the amount of air must be sufficient.

Hoses and fittings are equally important for a quality result. If a ¼ ”hose is used, then the air flow will be abnormal. Find a hose that is 3/8 in. ID.

The hose must be equipped with fittings and couplings capable of passing a fast air flow.

How to choose a nozzle

The spray nozzle is dimensioned. LKM flows through this hole, and a needle is inserted into this hole, which allows you to regulate the flow of paint. The needle moves back and forth with the trigger. When the trigger is fully lowered, the needle is spring-loaded and the nozzle orifice is sealed. Different nozzles are used for materials with different viscosities:

• 1.2 is the ideal size for local painting work;
• 1.3-1.6 - suitable for applying a base or varnish (also suitable for working with water-based paints);
• 1.4-1.7 is the ideal size for varnish and acrylic;
• 1.6-2.2 - for priming;
• 2.5-3.0 - for working with liquid putty.

These are some general recommendations that, in principle, can be ignored. Professional painters choose one size and use it perfectly with different materials. For priming, you need a larger size, otherwise you will have to dilute the primer more liquid.

When using acrylic primer, its filling property is very important. If diluted to a more fluid consistency, then this capacity will drop.

Working with water-borne paints

When working with water-soluble paints, it is best to use a separate tool. Replacing water-based paints with solvent-based materials may cause the ink to spray in flakes due to the ink curdling. It is also important that the spray guns do not corrode.

Spray systems

To understand what is the difference between different types of pistols, you need to consider the device and principle of operation.... So, the compressed air enters the device, through another channel the dye is supplied from the barrel. As the paint passes through the air cap, the air will split the paint and form a torch. The pressure determines the type of spray gun.

There are several types of sprayers:

• HP - for high pressure;
• HVLP - high volume at low pressure;
• LVPL - Low Volume at Low Pressure;
• HTE - High Efficiency.

In the video: which pistol to choose - HP. HVLP. LVPL.

HP system

This system is considered obsolete today. Pistols of this type have long been used for painting cars in workshops. Their work requires a pressure of 3-4 atm. At the time of spraying, the pressure should be about the same.

These nebulizers also require a small amount of air. Select a compressor for them of medium or low performance. The torch is wide, allowing you to evenly apply paintwork. The main disadvantage is the low transfer coefficient of paintwork materials to the painted surface.

These tools create fog during the spraying process that does not hit the surface. So, only 30-45% of the paint sprayed with this spray gets to the surface, the rest will settle in other places.

HVPL system

These tools are widely used today and are used by most professional painters. The HVPL spray gun requires a high volume of air and the spraying process is carried out at low pressures. To operate the pistol, you need from 2.5 to 3 atm. The spraying process is carried out at a pressure not exceeding 1 atm. At the expense of low pressure when spraying paint, almost all of it will settle on the surface to be treated.

Such spray guns have shown themselves excellently when working with metallic and mother-of-pearl paints. Among the disadvantages are the need for a powerful compressor and hose with an increased diameter, as well as the need to work from a distance.

LVLP system

A spray gun of such a plan removes the disadvantages of the sprayers discussed above. Different manufacturers different designations are used for this system. The task of these devices is to combine low air consumption with a high percentage of paint transfer to the surface.

The pistols of this system operate at a pressure of 1.6 to 2 atm. Spray paint is carried out at a pressure of 0.7-1.2 atm. The device consumes less air compared to HVLP models. This makes it possible to significantly reduce the power and performance of the compressor. The percentage of transfer of paintwork materials to the surface is more than 70%.

Electric paint guns

Along with pneumatic equipment, there is also an electric spray gun. Its advantage is that there is no need for a compressor for this system. A turbine is used instead. Professional auto painters do not use an electric spray gun due to its shortcomings.

It is stated that during the work there is a large consumption of paint. The nozzles included in the kit are too large to paint a car. Even if you know how to paint correctly, you will not be able to get a high-quality result. It is difficult to adjust the pressure to the right, so the paint comes out differently. The result is shagreen and other defects.

An electric spray gun is applicable if you need to paint a car when the quality of painting is not important. If quality is needed, then there must be a pneumatic tool.

Which spray gun is better depends on many factors. For experienced masters - professional Italian, for beginners - also Italian, but simpler. However, when painting with pneumatic equipment, the result will be many times better.

Conclusion

If painting will be frequent, then it is important to purchase a premium segment device. So, Ivata models are recommended. It is also possible to purchase HVLP models with a 1..4 mm nozzle. It is well suited for applying any paintwork materials.

The second option is to buy something inexpensive, but of high quality and at the same time universal. It is suitable for training, and then, with the accumulated experience, you can purchase a more serious model. And don't forget the compressor.

If you are already puzzled with the choice of a spray gun, you need to give you credit. Indeed, despite its increasing popularity, many painting professionals still use a roller, which entails an increase in duration and a decrease in quality compared to the work performed by a spray gun. However, not every professional is able to navigate the variety provided. Without studying in detail the characteristics and capabilities of the tool, you can throw money down the drain and not get desired result... Before comparing spray guns, let's figure out how the device works and what are its main functions.

What is a spray gun

A spray gun is, saying in simple words, paint sprayer. All spray guns consist of a pistol, a container for the solution and a device with which paint is pumped out of the container and pushed out of the nozzle of the gun. Thus, the sprayed paint lays down in small droplets in a uniform layer on the surface. Spray guns are not only easy to use, but, if used correctly, are able to provide a smooth, evenly painted surface of large volumes in a short time. And the high cost will pay off thanks to the tool life.

There are two main groups of spray guns according to the method of pumping and ejecting paintwork materials:

• Air or pneumatic;
• Airless - electric and rechargeable.

The design and operation of both types is significantly different.

Body painting with pneumatic spray

Electric spray painting

Pneumatic

Such a spray gun works due to the compressed air forced by the compressor. The gun is connected with a hose to the compressor, which, in turn, is connected to electricity. Pressurized air converts the paint into tiny particles and expels it from the gun nozzle. These tools handle both large surfaces and small details. The quality of painting significantly exceeds the quality of other methods, due to which they are widely used when painting cars.

Air spray gun design

The main disadvantages of these spray guns are fogging and significant loss of paintwork materials at the exit (up to 55%).

Considering that you immediately purchase a gun and a compressor, the cost of the tool is undoubtedly higher. You also need to keep in mind that the compressor must necessarily match the characteristics of the gun, otherwise there is a risk of damaging the equipment. This fact further complicates the choice of the buyer. But in return the buyer gets a powerful professional device.

All commercially available air guns are classified into basic types:

• HP - high pressure technology;
• LVLP - low pressure technology, small volume;
• HVLP - High Volume Low Pressure Technology.

They differ in the values ​​of pressure in the air chamber of the pistol and the air consumed from the compressor.

HP is a simplified technology. It is used in inexpensive pistols. The bottom line is that high level pressure allows you to consume relatively little air. This provides fast painting, but not the most the best quality... The disadvantages of this technology are strong particle swirling and fogging. Accordingly, we have uneconomical consumption of paint. The percentage of its transfer to the surface is 45-50%.

A distinctive feature of LVLP technology is the highest quality spraying, low air consumption, and a significant reduction in fogging. The percentage of paint transfer in some manufacturers reaches 90%. However, the operating speed is low due to the low pressure. These sprayers belong to the highest price category.

The HVLP is an upgraded HP spray gun. Air enters the gun at high pressure and paint is sprayed at low overpressure compressed air. Insignificant fogging and small losses of paintwork materials are inherent. The transfer rate of the painting material is 65%. The quality of the application is better. Their need for air is less than that of HP pistols, but higher than that of the LVLP. These pistols have earned the title of "super economical". They are used more often than others in car painting.

Electrical

These spray guns are powered by a built-in piston pump motor that pumps paint into the nozzle. Of course, the quality of painting with an electric spray is inferior to a pneumatic one, since paint particles are much larger due to the lack of compressed air. But you will get an inexpensive device that does not require special maintenance and additional purchases with the exception of material. These spray guns work from a 220V network. Suitable for small surfaces and are considered domestic.

Airless spray gun design

Electric spray guns are: floor-standing for professionals or hand-held for household purposes. The floor-standing ones have a large installation with a tank and a motor separate from the pistol.

Most convenient in living conditions work with a spray bottle with a transparent tank. This allows you to monitor paint consumption.

Comparison Chart of Electric and Pneumatic Spray Guns

How to easily decide on the choice of a good model? Compare your goals and requirements for spray guns with the characteristics that the manufacturer offers us. To do this, let us consider in more detail the parameters of the instrument, which are important to pay attention to when buying it.

Purpose of work and purpose

In order to choose a successful instrument model, first of all, determine the purpose for which you decided to buy.

For repairs in an apartment or house every 5 years, the cost of purchasing pneumatic equipment with a compressor is not comparable to the result. Even if in the future you plan to periodically tint something, it is better to purchase a standard electric spray gun.

For garage paintwork, whether you are an amateur or a professional, contact the manufacturers of pneumatic spray guns. In painting parts, quality is the main indicator of clean work. Inexpensive pneumatic devices, but certainly a proven brand, cope with all stages of preparatory and finishing better than others. Painting speed will depend on many factors: torch size, outlet pressure, your skill.

Viscosity of formulations

Electric spray guns are more capricious in relation to paints and varnishes. The DIN viscosity index, indicated in the passport of any spray gun, must not be lower than the viscosity of your composition. Therefore, builders often resort to diluting paint with water. But thick compositions and putty to apply with such devices, most likely, will not work.

Pneumatic spray guns are capable of working with more viscous formulations. However, even here it all depends on the type of gun, the size of the needle and the pressure. With high-pressure spray guns, the outgoing jet primer, paint, varnish or other viscous materials lay on the surface in an ideal layer, without drips, streaks and layering. As for low pressure tools, if it is easy to pick up LVLP for thick paint, then it will not have enough pressure for putty.

Availability of adjustments

When choosing a spray gun, electric or pneumatic, be sure to check for adjustments... With their help, you can customize your apparatus for the surface to be painted and the specific composition, changing the pressure, limiting the needle travel, which is responsible for the paint supply, the shape and size of the torch.

Also pay attention to the package of the tool. It is best if the kit includes replaceable nozzles with different diameters, a pressure gauge, and hoses of different lengths.

Tank location

When choosing a sprayer, the location of the composition reservoir is important. It all depends on the distance and location of the surface for finishing. For example, when performing work with a device with a bottom location of the tank, it is recommended to keep it strictly vertical to inject paint. However, the vertical arrangement of the tank is inconvenient for painting ceilings.

Tool mobility

Do you ever happen to spray paint away from electricity? You decide. For this case, we propose to get acquainted with the airless battery spray gun.

What is its advantage? Of course, in mobility. But there are also a number of disadvantages:

• Tool weight due to the presence of a battery;
• Low power;
• Limited working time;
• A drop in pressure with a discharged battery and, as a result, poor-quality paint.

Therefore, even if you are going to perform extremely small household tasks, and the mobility of the tool is not in the first place, we advise you to purchase a spray gun from the category of household, working from an outlet.

Performance and power

Finally, when choosing an atomizer, the first thing a customer looks at is performance and power. And here you need a cold calculation.

When buying a pneumatic device, it is recommended to first purchase a gun, and then select a compressor for its characteristics. Based on the performance of the gun, ie the air consumed, select a compressor with a “margin”. If the compressor is selected incorrectly, then the pressure drops too quickly or the motor runs to its limit, as a result of which it may overheat, shutdown and early wear of the piston group.

When comparing tools, it is also worth paying attention to the fact that in the passport the company indicates the productivity at the entrance. Air compression losses occur depending on the model. Therefore, the actual output capacity is 65–70% of the indicated one.

The average power of the compressors is 1.2–1.8 kW, which is sufficient for the operation of the entire unit. The volume of the receiver for most types of work is sufficient within 24–50 liters.

With airless spray guns, things are easier. The manufacturer has provided for and balanced the characteristics of the pistol and the motor with the pump. Focusing on the price and performance, you can choose the best device for yourself. But keep in mind: the more power and performance, the better the device will cope with thick compositions.

Experts advise adjusting the gun for each composition and material and checking it on a separate surface. The optimal choice of a needle is 1.3–1.4 mm.

Summing up the choice of a spray gun, we present you the most popular proven brands of manufacturers that are in demand among professionals and amateurs.

• Bosch. Bosch manufactures low-cost and compact electric spray guns for home use. The most famous models: PFS55, PFS65. The pump and motor of the smaller models are designed in-line. Bosch spray guns are used for surface treatment of walls and ceilings, for painting small parts. The average productivity is 0.11 l / min. The tools are easy to use and maintain. The main disadvantage of these spray guns is the restriction on the use of certain types of paintwork materials, such as: alkaline, latex, dispersion paints and other difficult to spray compositions. Therefore, prices for spray guns start at 4000 rubles.
• Wagner. German air-type spray guns Wagner make good competition for Bosh. Models costing from 5000 r. (Wagner W550) are suitable only for liquid paints, productivity is 0.13 l / min. More expensive sprayers costing from 12,000 rubles. (Wagner W665) You can also apply thick formulations, including water-dispersion paints, which cannot but please the painter.
