Type

The type is indicated by the energy source from which the spray gun operates. Nowadays, you can find pneumatic, electric(mains and battery), as well as mechanical and gasoline models. Here are their main features:

— Pneumatic. Spray guns powered by compressed air from an external compressor. In other words, the delivery package for such a tool includes only a spray gun (gun, airbrush, etc.); it requires a separate compressor to operate. At first glance, this creates certain inconveniences; however, such a configuration also has noticeable advantages. Firstly, there is no need to overpay for a compressor if it is already “on the farm” (a separate example of such a situation is a construction site where a powerful stationary compressor is used for several pneumatic tools). Secondly, the nozzle and compressor can be selected at your own discretion, without relying on the equipment selected by the manufacturer. In light of this, most modern spray guns are made pneumatic. The obvious disadvantages of such devices include their unsuitability for working with airless spray systems, however, such systems are used much less frequently than air systems, so this nuance is not key.

- Electric. In this case, we mean wall-powered spray guns (battery-powered models are placed in a separate category,...see below). Devices of this type consist of the sprayer itself, as well as a compressor (built-in or remote). One of the advantages of this option is the presence of a compressor, thanks to which such a spray gun, in fact, only needs an outlet. In addition, such units can use both air and airless spray systems. The disadvantages of electric models include a higher cost than pneumatic ones, as well as the inability to select a working nozzle and a compressor separately - as a rule, spray guns of this type are sold in ready-made kits.

- Rechargeable. Spray guns equipped with electric compressors powered by their own batteries. The key advantage of such tools is their autonomy, the ability to work even in the absence of sockets nearby. On the other hand, it is difficult to achieve high power and performance with a battery; the continuous operation time of such sprayers is limited by the battery charge (and a source of electricity will still be required to replenish the charge); and the design itself is more complex and more expensive than that of analogues powered from an outlet. Therefore, cordless spray guns are not particularly widespread in our time.

- Mechanical. Units in which paint is supplied by the user’s muscular strength - in other words, to do this, you need to manually pump the pump lever. This operating scheme is as simple and reliable as possible, but it is poorly suited for traditional sprayers. Therefore, “mechanics” is extremely rare in our time, mainly among rollers (see “View”).

- Gasoline. Models with this type of power supply combine high power and independence from electrical networks, but they are quite bulky, more complex to operate and repair, more expensive (both in terms of their own cost and the price of fuel) and are generally designed for industrial use outdoors . Therefore, they are not widely used and are used where, for one reason or another, electrical analogues are not applicable.

Power consumption

The power consumed by the operation of an electric tool (see "Type").

Most modern spray guns, even performant ones, have a rather low power: for example, models with more than 1 kW are extremely rare, and in most cases, power consumption does not exceed 500 W at all. So when connecting such equipment to sockets, there are usually no problems; only single units of high performance, requiring 3.5 kW or more, have to be connected according to special rules (directly to the shield). In other cases, data on power consumption is most often not needed for normal use and may be required only for specific tasks — for example, to calculate the load on an autonomous generator.

Rated pressure

Nominal air pressure in the spray gun.

The general meaning of this parameter depends on the type of instrument (see above). So, in pneumatic models, nominal pressure data is required for connection to an external compressor. It is this pressure that this compressor must create at the inlet to the atomizer; too low values will lead to a decrease in efficiency, too high are fraught with breakdowns and even accidents with injury to others.

In turn, for electric models, the nominal pressure is the air pressure created by the unit's own compressor; the complete atomizer was originally designed for the same pressure. So in this case, this parameter is more of a reference than practically significant; it may be useful only for connecting replacement nozzles to the compressor (or vice versa, for using an existing nozzle with a third-party compressor).

As for specific pressure values, they are primarily determined by the spray system (see below). The diversity here is quite high: the most modest units give out less than 2 bar, 2-5 bar compressors are quite popular , 5-10 bar models are relatively rare, and some powerful performance solutions provide a pressure of 100 bar or more.

Paint consumption

Consumption of paint or other material (for example, mortar for plaster) when the spray gun is operating in normal mode.

The higher the flow rate, the more material the tool can apply per unit of time, the better it is suitable for processing large areas and for applying thick coatings. On the other hand, not all types of work require high productivity, and sometimes relatively low consumption is optimal. Detailed recommendations on this subject for different situations can be found in special sources.

Nozzle size

The diameter of the nozzle at the outlet of the spray gun.

It is from this nozzle that paint or other working material comes out. And the productivity and spot size at the exit depend on the diameter. Accordingly, larger nozzles are better suited for processing large surfaces, while smaller nozzles provide greater precision and accuracy. Thus, this parameter is directly related to the type of device (see above). There are also spray guns with a replaceable nozzle, when more than one nozzle is provided in the kit, which expands the possibilities of using the device.

Container volume

The total volume of the paint reservoir supplied with the gun. Large tank, on the one hand, allows you to "charge" a lot of material and work for a long time. On the other hand, it increases the size and weight of the device; and a large amount of paint will also weigh accordingly (although for models with a separate tank location - see above - this is not critical). Therefore, the thinner and more delicate the work for which the spray gun is designed, the, as a rule, the smaller the tank volume : for example, in airbrushes (see "View") it rarely exceeds 50 ml, and in plaster models, in turn, can be measured liters. Therefore, most models have a volume of no more than a liter, namely 500 ml, 600 ml, 700 ml, 800 ml, 1000 ml.

Tank material

The material from which the complete reservoir of the spray gun is made.

— Plastic. Plastic is characterized by a combination of low cost with lightness and reliability. It is somewhat inferior to metal in strength, however, in the case of tanks for spray guns, this is not critical; in addition, the plastic tank can be made transparent, which makes it easier to keep track of the paint level. Thanks to all this, plastic is found in devices of all types and price categories. Among its shortcomings, sensitivity to certain types of solvents can be noted; however, there are resistant varieties of plastic that are practically devoid of this feature.

Metal. The main advantage of metal tanks is high strength and reliability. On the other hand, they are noticeably more expensive and heavier than plastic ones, and besides, they are not transparent (at best, a built-in indicator in the form of a window can be provided). Because of this, the metal is less common.

— Glass. The glass reservoirs are transparent and allow you to easily control the amount of remaining paint. In addition, this material is chemically inert and compatible with almost any working substance. However, glass has a serious drawback — fragility, which is why it has not received much distribution and is found only in some models of airbrushes (see "View").

Remote compressor

The presence of a remote compressor in the design of the spray gun.

This feature means that, firstly, the unit is equipped with its own compressor (that is, it is electrical, see "Type"), and secondly, this compressor (or pump for airless spraying) is made separately from the sprayer and is connected to it special hose. Thanks to this design, the atomizer itself is as light and compact as possible, which is especially important for large volumes of work or for delicate work that requires maximum precision and accuracy. In light of the latter, all electric airbrushes (see "View") are equipped with remote compressors, although this feature is also found in other types of spray guns — in particular, this design is mandatory for paint stations (see ibid.).

Shoulder strap

The presence of a belt for holding on the shoulder in the design of the spray gun.

This feature is found mainly in models with an external compressor (see above). The sling allows the user to carry the compressor close to the gun, so the air hose does not restrict tool movement.
