Spray gun selection. Which spray gun to choose: electric or pneumatic? Electric spray gun: which one to choose - manual or floor

To begin with, let's deal with the accepted designations of spray types - they directly indicate the characteristic features of the spray gun.

The simplest systems are spray guns HP (High Pressure). They are demanding on pressure and compressor performance, their working pressure in the air cap is higher than other types. Due to this, the paint breaks up into small drops, gives a powerful torch, but also “passes” it strongly. Therefore, for these types of spray guns, the material consumption is the largest; when working, one should not forget about a respirator and an exhaust hood. The surrounding area should be protected from pollination. But, for example, if you need a good breakdown of varnish, then having an HP pistol in stock will not hurt. A more interesting option for work - RP (Reduced Pressure). In fact, this is the same classic design, but it works softer, there is less experience.

Spray guns HVLP (High Volume, Low Pressure) operate at low pressure in the air cap, so that the torch is soft and does not hit far, and the paint consumption is economical. On the other hand, it is already more difficult to make a “mirror” on a varnish with them. That is, for example, when painting with “metallic”, it is more convenient to put the base with an HVLP spray gun, and for varnish, take the “good old” HP. Please note that the torch of such sprayers is “short”, and, for example, it is inconvenient for them to pour over the roof of a car.

What then does it mean LVLP? Based on the interpretation of Low Volume, Low Pressure, such spray guns not only operate at reduced pressure, but the material is also fed in a small amount. A good option for small areas that are better to work from a short distance. For example, when painting a forged grating, more productive spray guns will either immediately sag, or too much paint will “fly away” into free space. However, in any case, it is not the gun that paints, but the hand - a certain skill is always needed.

Electric spray guns- a specific thing. They are convenient primarily for large areas without special quality requirements. For example, to paint walls with water-based paint using a pneumatic spray gun, you will need such a compressor that not everyone will drag it into an apartment. But an electric spray gun, with which only a completely undemanding person can paint a car, will help out here. Due to the low air pressure at the inlet, they have minimal dust, indoors this is important. But the performance will allow you not to spend a lot of time on work.

An airbrush or spray gun is one of the most important tools that is needed for painting a car. Its peculiarity is the spraying of the dye in an airborne way by means of compressed air pressure. There are a wide variety of such tools on the market today, and it is difficult for many to decide on the choice of the appropriate option. How to choose an airbrush for painting a car among the models presented in stores, and what characteristics should you pay attention to?

Spray guns for paint, such 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 due to different methods of working with them. With external resemblance to pneumatic sprayers, spray guns are seriously different - they have a different structure of air heads, as well as different designs of air supply channels.

The features of each particular type of sprayer significantly affect the comfort during operation, as well as during painting work.

How often will the spray gun be used? 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 painting gun that can do its job well. For such purposes, inexpensive HVLP devices with the necessary characteristics are suitable.

To choose a tool, you should also determine the tasks that will have to be solved. There are atomizers with different spray systems. 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 atomizers should you have?

Experts recommend having several 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 an airbrush for each material and for each task. In this case, you do not have to solve problems with 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 spray gun.

Compressor

It is recommended to choose a spray gun according to the characteristics of the compressor. It is possible in another way - after acquiring a gun, choose a compressor for it. The compressor must deliver the required volume under pressure at all times while using 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 1.5 times more than is required for the normal operation of the gun at pressure.

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

No less important for a quality result are hoses and fittings. If a ¼ inch hose is used, then the air passage will be abnormal. Find a hose that has a 3/8 inch 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 has a certain size. Paint 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 through the trigger. When the trigger is fully lowered, the needle is pressed against the spring and the nozzle opening is hermetically sealed. Different nozzles are used for materials with different viscosities:

1.2 - the ideal size for local painting work;
1.3-1.6 - suitable for applying a base or varnish (also suitable for working with water-soluble paints);
1.4-1.7 - 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, which, in principle, can be ignored. Professional painters choose one size and use it well with different materials. For priming, you need a larger size, otherwise you will have to dilute the primer more fluidly.

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

Working with water-based paints

When working with water-soluble coatings, it is best to use a separate tool. Replacing water-based paints with solvent-based materials may cause the colorant to flake due to cured paint. It is also important that the spray guns do not corrode.

Spray systems

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

There are several types of atomizers:

HP - for high pressure;
HVLP - high volume at low pressure;
LVPL - low volume at low pressure;
HTE - high efficiency.

On the video: which gun to choose - HP. HVLP. LVPL.

HP system

This system is now considered obsolete. Pistols of this type have long been used for painting cars in workshops. For their operation, a pressure of 3-4 atm is required. At the time of spraying, the pressure should be about the same.

These sprayers also require a small volume of air. Choose a compressor for them of medium or low productivity. The torch is wide, allowing you to evenly apply paintwork materials. The main disadvantage is the low coefficient of transfer of paintwork materials to the surface to be painted.

Such tools in the process of spraying create a mist that does not fall on the surface. So, only 30-45% of the paint sprayed with this sprayer hits 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 large volume of air and the spraying process is carried out at low pressures. For the operation of the gun, it is necessary from 2.5 to 3 atm. The spraying process is carried out at a pressure not higher than 1 atm. Due to the low pressure when spraying paint, almost all of it will settle on the surface to be treated.

Such spray guns proved to be excellent when working with metallic and mother-of-pearl paints. Among the disadvantages are the need for a productive compressor and a hose with an increased diameter, as well as the need to work at a distance.

LVLP system

With a spray gun of this kind, the shortcomings of the sprayers discussed above are removed. Different manufacturers use different designations for this system. The task of these devices is to combine low air consumption with a high percentage of paintwork transfer to the surface.

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 coatings to the surface is more than 70%.

Electric spray guns

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

It is stated that during operation there is a large consumption of paint. The nozzles that come with the kit are too big 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 right pressure, so the paint comes out in different ways. 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 you need quality, then you must have a pneumatic tool.

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

Conclusion

If painting is frequent, then it is important to purchase a premium segment device. So, they recommend models from Ivata. You can also purchase HVLP models with a nozzle of 1..4 mm. It is well suited for applying any coatings.

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.

Even some 10 years ago, almost no one suspected the existence of electric spray guns. There was no particular choice, and pneumatic spray guns were used everywhere: at home and in the country, in the workshop and in production. They painted everything: from the car and furniture, to the fence, garage and walls of the country house. I remember five years ago I begged for an electric spray gun from representatives of the Wagner company, at least one piece. They brought me an airbrush, and two at once: Wagner W550 and Wagner W560, which still stands in our office as a museum piece.

Today, electric spray guns have become so common on sale, they are so easy to operate that many people have a question, and whether to switch completely from pneumatic spray guns to electric ones.

So, what to choose: pneumatics or electrics? Let's reason in order.

From the point of view of fire safety, and the fire regulations in force in our country, the use of electric painting equipment in a paint shop or spray booth is prohibited, therefore, with regard to painting production, switching from pneumatic spray guns to electric ones is impossible, or, as they say, undesirable.

Again, most HVLP electric spray guns spray paint, i.e. the paint in them is supplied under very low pressure with a very large volume of air. With this type of spraying, paint drops are quite large, because. under low pressure, the paint material is not completely broken down by air. A tangible plus from such spraying with successful and correct dilution of the paint is the almost complete absence of paint fog, because. a large volume of air from the spray gun, as it were, structures the direction of movement of the paint torch.

Most electric spray guns have a fairly large paint nozzle (more than 1.5 mm), which allows some of them, for example, Wagner spray guns, to apply fairly viscous paints, and even water-based paints. But large nozzles are not well suited for spraying liquid paints, which are usually used in a paint shop or spray booth. When working with such spray guns, for example, when painting furniture at a factory or a car in a car service, you can get a “wash” and overspending of paint.

Most electric spray guns, with the exception of Wagner and Earlex, I think, do not have interchangeable nozzles with different types of nozzle and air cap. Because of this, you will have to somehow adjust all the paints to one viscosity suitable for this spray gun. Therefore, some paints will flow when sprayed, some will clog nozzles, which will significantly complicate the work with electric spray guns if you still risk using them in production.

Pneumatic spray guns are professional in their use. They are available in a variety of pressures, from low HVLP (0.7 bar) to regular pressure high air spray paint (3.5 bar). Plus, for example, Devilbiss spray guns have a large number of interchangeable air caps and interchangeable nozzles of different diameters.

In addition, there are various modifications of pneumatic spray guns according to the type of execution. They can be with an upper or lower tank, as well as with forced paint supply. Tanks are of various sizes: from 100 ml and more. Thanks to this, you will be able to more accurately select the spray gun specifically for your production.

Air pneumatic spray guns are designed for high quality atomization, to obtain the best quality of the painted surface. The paints that are sprayed with air guns are often highly diluted, and the design of the air caps is made in such a way as to break up the paint as much as possible and make its particles of the smallest diameter. Therefore, painting with such spray guns goes in several layers, because. the layers are thin, and the thickness of the layer must be gained. Plus, due to the strong breakdown of the paint, the use of pneumatic spray guns is recommended only in the spray booth, because. continuous extraction of colorful mist is needed.

Based on the foregoing, I can say that it is possible to compare these two systems of spray guns, but they are still diverse in their purpose. If you need to paint at home, in an apartment or in a country house, then choose an electric spray gun for domestic work. If you have a production, serial or piece, you have a spray booth, you produce high quality products, then take a good pneumatic spray gun, but do not forget to choose the right air compressor for painting.

The need for repairs is always puzzling, because there are so many different tools to purchase ... axes, saws, hammers, etc. This is especially often a problem when you have to paint walls or floors. In this case, using a brush or roller is somehow not very convenient, and not practical, and we decided to select for you the best electric spray guns that will make the task easier. This rating contains only carefully tested devices, and our goal is to help you choose the right model from a rich assortment.

About what spray guns are, what price category they belong to and what characteristics they have that should be considered when choosing, see this video:

Using the best electric spray guns for home or office renovations, you can significantly speed up the process, avoid difficulties and get a professional result. In any case, this device always works more reliably than a beginner or even a professional do-it-yourselfer.

Carrying out painting work is a rather time-consuming task, especially if you need to apply a layer of paint, varnish or protective coating on an uneven surface or a large surface area. The spray gun (sprayer) greatly simplifies the task, with the help of which the application of various coatings occurs quickly, efficiently and with minimal physical costs.

The device is designed to create an aerosol, that is, small particles of a substance suspended in the air, for example, paint, varnish, whitewash solution, antiseptic, etc. More precisely, an airbrush is needed for the directed transfer of small particles of a substance to any surface in an even layer, without the formation of bubbles and streaks.

The device for spraying paint and other substances in its various modifications is used in the following areas.

Types of spray guns

The family of paint sprayers is usually divided into types, and their device determines the principle of applying paint and varnish and protective coatings. The following types of spray guns are presented on the market for painting equipment:

electrical;
pneumatic;
rechargeable;
airless;
high and low pressure;
with top and bottom tank.

Let's see what is the difference between them.

Electric spray guns

The electric paint sprayer is a device without a compressor, but in which a piston pump is built in, driven by an electromagnet with an oscillating bar. Also, some paint sprayers are with integrated compressor, which creates an air flow due to the rotation of the turbine by an electric motor.

Turbine spray gun just like the piston one, it works from a 220 V network. And since this type of device does not require a special purchase of a compressor with a receiver, they are often chosen for domestic use.

In addition, there are electric paint sprayers with external compressor. The latter can be large and designed to be placed on the floor. Basically, these are devices for professional use.

Household appliances are compact in size, and during operation they are hung on the shoulder with the help of a strap that is included in the set for the devices.

Pneumatic spray guns

Pneumatic spray gun works only from compressed air.

For the production of the last a compressor is required. To stabilize the air flow and maintain the air pressure at the same level, a receiver is installed between the compressor and the spray gun.

As a rule, the pneumatic type of device is a professional spray gun, thanks to which they achieve the ideal quality of applying paint and varnish coatings. The tool has a standard nozzle diameter of 1.4 mm. If you install a nozzle with a diameter of 1.8 mm or more, the device will turn into a primer spray gun.

Among the professional models you can see and electronic spray gun, i.e. with a digital manometer. The presence of an electronic pressure gauge allows you to fine-tune the device, which is very important if you want to achieve the same dye spray intensity.

Pneumatic devices also include automatic paint sprayer which is mainly used in production as part of automatic installations for applying various decorative and protective coatings.

Advice! To understand which spray gun is better - electric or pneumatic (air), you need to know for what purposes the device will be used. For domestic needs, if there are no high requirements for the quality of the coating, an electric spray gun is well suited. But for painting cars, it is better to use a pneumatic tool.

Cordless Sprayers

Battery-powered paint sprayers are analogous to conventional electrical appliances. The only advantage of cordless spray guns is mobility, which makes it possible to work in places where there is no electrical network.

But it should be borne in mind that this manual spray gun will not be able to work for a long time due to battery discharge. On average, such a device works for 20-30 minutes, after which the battery needs to be replaced. Therefore, a cordless spray gun is usually used to perform small volume work.

Airless Spray Guns

As the name suggests, paint is sprayed without the use of compressed air. In airless spray (plunger) spray guns, paint is fed into the nozzle under high pressure. To ensure the supply of paint to the plunger spray gun, a piston pump driven by an electric motor is used.

To decide which spray gun is better - air or airless, you need to understand for what purposes the devices will be used.

Air ink transfer method implies the formation of a soft torch of the coloring matter, which is applied to the treated surface in a thin layer. Thanks to this, a high quality coating is achieved, including in hard-to-reach or relief places. But due to the low viscosity of the paintwork material and low air pressure, not all small particles of the substance reach the surface to be painted. A considerable part of them remains in the air and surrounds the painter.

Airless spray gun, as mentioned above, operates at high pressure, which makes it possible to use a more viscous dye. Consequently, its particles have a greater mass than with air spraying, and all reach the surface to be painted, without swirling. In this case, the paint is consumed more economically. Although the airless method can achieve high quality paintwork, this type of spray gun is not suitable for painting embossed parts. This is explained by the greater density of the paint, which will be applied unevenly on a product of complex design and form “sagging”.

High and low pressure paint sprayers

High pressure units(up to 56 atmospheres) are designed for spraying viscous paints and varnishes. In addition, these spray guns can apply bitumen-based mastics, primers and compounds with anti-corrosion properties.

The low pressure spray gun is the most popular machine among car painters. The paint sprayer can operate at a system pressure of 2 atm. and allows you to save up to 30% of paint and varnish compositions.

Important! The operation of the device requires a compressor with a receiver and, preferably, with a gearbox that allows you to adjust the air pressure at the gun inlet.

Appliances with upper and lower tank

If the spray gun has tank at the top, then the supply of paint to the tool occurs due to the force of attraction. The spray gun with the upper tank is used for applying various coatings on small areas. Devices with a top tank are more economical, since the paint is completely consumed in them, which cannot be said about the tool, where the tank for the spray gun is installed at the bottom.

At lower position of the tank liquid is supplied to the device due to the rarefaction created by the compressed air flow. An airbrush with a lower tank is usually used for coating large areas, since the volume of the container of such a device significantly exceeds the volume of the upper tank.

Powder machines

A powder spray gun is a device that works with dry dyes. The main element of the device is an electrostatic converter.

But still, the operation of the device is impossible without compressed air. The latter, passing through the paint sprayer, transfers the powder towards the electrostatic converter, where it is ionized. Next, the ionized powder particles are blown through the nozzle onto the surface to be painted, which has the opposite charge, and stick to it.

Important! Powder paint sprayers allow you to apply a uniform layer of paint not only on flat surfaces, but also on embossed ones.

There are also powder spray guns that do not use electricity to ionize the powder particles. Such devices are called tribostatic.

Powder dye particles in the gun are ionized due to friction against the inner walls of the tribostatic barrel and collision with each other, after which they are blown onto the surface to be treated by an air stream.

Pistol type

All types of paint sprayers also differ in the type of gun.

The choice of spray gun for domestic and professional use

To choose the right airbrush for home or professional use, it is necessary to take into account such characteristics of the tool as:

class (type) of paint sprayer;
tank material and its location;
dimensions and weight;
nozzle size;
power (for electric devices).

Spray gun class

Since an HVLP class paint sprayer can operate at low pressure and provide an acceptable quality of staining, it is better to buy just such a gun model for your home. Of course, for the professional sector, you will need to purchase an industrial LVLP class tool.

Tank material and location

The tank for paint and other compounds is made either of plastic or metal. plastic cisterns convenient in that they are translucent and allow you to visually determine the level of the paintwork material poured into it. In favor metal containers for spray guns, it says that they can be washed with aggressive solvents that can damage the plastic tank.

Advice! For home use, a device with a plastic tank will suffice, since sparingly soluble coloring compounds are almost never used in everyday life.

Also, when choosing an airbrush, you should consider cistern location, on which it depends whether the painter will be able to perform this or that work. The top location of the container is considered universal and allows the application of compositions both on the ceiling and on the walls. In some appliances, the upper tank can be connected with a flexible hose, allowing you to set the tank in the desired position.

When the tank is lowered, the device will work only in horizontal position. If the tool is raised vertically, for example, for whitewashing the ceiling, then the solution will stop flowing into the tool. The only thing that the lower tank is convenient for is its increased volume, which allows you to pour a large amount of paint or other composition into it.

Dimensions and weight

To a large extent, these parameters are for electric paint sprayers. The larger the size of the compressor or pump, the higher the performance of the device for spraying formulations. Therefore, professional craftsmen prefer to use electric spray guns with an external compressor (floor).

Household electric paint sprayers are small in size, have a pump built into the gun and are convenient for small painting jobs around the house. In addition, this mini tool can be produced with small external compressor. Due to its low weight, it can be carried on the shoulder while spraying.

Nozzle size

The nozzle from the spray gun, or rather the diameter of its outlet (nozzle), directly affects the size of the drop of paint material that is sprayed. When choosing a paint sprayer, you need to know what types of work will be carried out with its help. For spraying various materials, it is required to select the appropriate nozzle diameter:

for spraying water-based paints, as well as applying base and varnish, a nozzle diameter of 1.2-1.6 mm is required;
for acrylic-based paints and varnishes, a nozzle with a diameter of 1.4-1.7 mm is required;
primers work well with devices having a nozzle with a diameter of 1.5-2.2 mm;
for thick compositions, for example, liquid putties, a nozzle diameter of 2.5-3 mm is required.

Advice! For professional use, you should buy a device whose nozzle heads are made of stainless steel. These elements will last longer than their plastic counterparts, which do not withstand frequent washing in solvents.

Power of electric spray guns

Devices that have power up to 500 W, are considered household, have a low cost and are more suitable for beginner painters. They do not work well with thick compositions, apply the dye unevenly, which affects the quality of the coating.

For professional use, you should choose devices power over 500 W, which can cope with compositions of any viscosity and evenly spray them onto the treated surface.

Useful extras

Since paint sprayers are used to perform a large number of different types of work, in some cases, additional elements are connected to them for more efficient use of devices.
