Comparison Black&Decker HVLP200 vs MIOL 79-560

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.

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.

Nominal air flow rate when the spray gun is operating in normal mode.

This parameter is of key importance for a pneumatic tool (see "Type"): the compressor to which such a sprayer is connected must provide the appropriate air supply rate, otherwise normal operation will not be possible. In turn, in electric models, this indicator is more of a reference — the complete compressor, by definition, corresponds to the characteristics of the sprayer, and it makes sense to pay attention to the flow rate only if the working nozzle of the electric spray gun is planned to be used with a "non-native" compressor.

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.

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.

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").

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.).

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.

The length of the hose supplied with the tool.

This indicator has two meanings. On the one hand, the long hose provides more freedom of movement, allowing you to work farther from the compressor; this is especially important when used with powerful, heavy compressors that are not designed to be carried around often. On the other hand, in some cases a relatively short hose is more convenient; a typical example of such a situation is the presence on the farm of a compact compressor that can be constantly carried with you.

Actually, if the compressor is initially included in the delivery set, then the manufacturer chooses the length of the hose, taking into account its features. But if the spray gun is bought without a compressor, you should pay special attention to this parameter. As for the specific length, the shortest hoses found in modern spray guns do not exceed 2 m, but this is often quite enough; a length of 2 – 5 m can be called an average, and in powerful models (mainly paint stations) you can find hoses and more than 5 m.
