Max. spraying distance

The longest distance a sprayer can effectively spray a liquid or powder. Usually, the horizontal range is implied, however, for “long-range” models, values bare also given for vertical spraying — in such units, the difference between horizontal and vertical ranges can be very noticeable.

A “long-range” sprayer (for 10–15 m or more) is convenient in that it allows you to process a large area without moving, and also to reach high branches without using ladders. On the other hand, a long range requires appropriate power, which affects the price, weight and dimensions of the unit — despite the fact that such capabilities are not always required: for example, for a cramped greenhouse, an atomizer with a short range ( 5 – 10 m, and often and less) So it is worth choosing according to this indicator, taking into account the features of the planned work.

Hose length

The length of the hose supplied with the sprayer.

The longer the hose, the farther the spray tube can be reached without moving the sprayer itself. However, this is true mainly for wheeled and universal sprayers (see "Carrying type"). In shoulder-mounted units, the hose is usually selected in such a way that it is enough to comfortably hold the tube in your hand, and this parameter in such models most often does not exceed 150 cm.

It is also worth considering that long hoses can be quite bulky; however, this disadvantage is often eliminated by the use of spiral hoses, which are stretched to their full length only when necessary.

Cylinder volume

The volume of one cylinder in an internal combustion engine installed in a sprayer. In fact, we are talking about the working volume of the entire engine, because. in this technique, only single-cylinder internal combustion engines are used.

In general, a large cylinder volume allows you to achieve high power, but power also depends on some engine characteristics (primarily the type of internal combustion engine, see above). And the performance characteristics of the sprayers themselves with the same engine power can also be different. But what directly depends on the volume of the engine is fuel consumption: a larger volume, usually, requires more fuel.

Power

Engine power of the gasoline sprayer (see "Type") in horsepower.

Power directly affects the spraying range and the performance of the unit, according to this indicator, it is quite possible to assess the overall level of the device. However note that manufacturers can indicate this characteristic in different ways: some give the rated power (when the engine is running in normal mode), others give the maximum power (at peak load). Therefore, when choosing and comparing, it is worth considering not only this indicator, but also other basic characteristics.

As for horsepower, this unit is traditionally used to assess the power of an internal combustion engine. 1 HP approximately equal to 735 watts.

Power

Sprayer engine power in kilowatts. Watt (kilowatt) is a universal unit used for all types of engines, but in fact this parameter is indicated mainly for gasoline units (see "Type"). This is due to the fact that electric sprayers — even the most powerful and heavy ones — consume less than 1 kW, which does not create any problems with connecting to a conventional outlet; so for such units there is no need to specify engine power.

Power directly affects the spraying range and the performance of the unit, according to this indicator, it is quite possible to assess the overall level of the device. However note that manufacturers can indicate this characteristic in different ways: some give the rated power (when the engine is running in normal mode), others — the maximum (at peak load). Therefore, when choosing and comparing, it is worth considering not only this indicator, but also other basic characteristics.

As for specific figures, in the most modest models this figure does not exceed 1 kW ; 1.1 – 2 kW can be called the average value; and many gasoline sprayers are equipped with motors and more than 2 kW.

Fuel tank capacity

The volume of the fuel tank in the petrol sprayer (see "Type").

Knowing the fuel consumption (see below), the volume of the tank can be used to estimate the time of continuous operation without refueling. In general, a larger tank, on the one hand, allows you to work longer between refueling, on the other hand, it affects the dimensions and weight of the entire unit. In addition, the power of the internal combustion engine in the sprayers is relatively low and they require little fuel, and you still have to fill the main tank every few minutes. In light of all this, manufacturers usually install tanks in sprayers with a volume of 0.5 to 2 liters — this is quite enough for at least half an hour of work (often more).

Spray lock

A device that allows you to fix the trigger (switch) of the sprayer in the pressed position. This is especially convenient for large volumes of work: holding the trigger manually for a long time is rather tiring, and the continuous watering lock allows you to avoid unnecessary stress on your hands.

Note that this feature can be found in all types of sprayers (see above), including lever ones — many models with this type of action are equipped with both a pumping lever and a separate trigger that must be kept pressed during operation.

Dry powder spray

Possibility of work of a sprayer on dispersion of powder.

In addition to liquid, some jobs also have to deal with powder. When for effective supply of the powder, a pressure pump is required, while the liquid can also flow by gravity, under its own weight. Such a pump is not provided in all sprayers; therefore, only those models in which such a possibility is directly stated can be used to work with powder.

Weight

The total weight of the sprayer. Specified without taking into account the liquid or powder in the working tank; at the same time, for battery models (see “Type”), usually, the weight is given with a complete battery, and for gasoline models, on the contrary, “dry” weight, without fuel in the tank.
