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.

Air consumption

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.

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.

Hose length

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.
