Productivity (liquid)

Maximum performance of the sprayer when working with liquid; Please note that in pump (see "Type of pumping") and battery (see "Type") models, the actual performance may decrease as the air supply or battery charge is exhausted.

High performance allows you to quickly process large areas; moreover, it is often combined with a good spraying distance (see below). On the other hand, such models require fairly large tanks — or they often have to be refilled; neither one nor the other contributes to the convenience of work. In addition, over-capacity is even more undesirable than under-capacity: a low-capacity sprayer will just take longer to process, and a too-capacity sprayer can ruin the job by “overdosing” the chemical. Therefore, it makes sense to use high-performance devices only for specific tasks.

Detailed data on optimal performance values for different situations can be found in special sources.

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.

Max. pressure

The maximum operating pressure of the sprayer.

High pressure allows to achieve good spraying performance and range, however, actual performance can vary with units with the same pressure. Therefore, in general, the indicator is for reference (the lion's share of models has a pressure of 3 bar and 4 bar, and it is only possible to compare different models by it approximately. When choosing, it makes sense to focus on more practical characteristics — performance, range, etc.

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.

Spray wand length

The length of the spray tube supplied with the sprayer.

A long tube, on the one hand, allows you to reach far without leaving your seat and without using stools, ladders, etc.; on the other hand, it is not very manoeuvrable and can be inconvenient when working in tight spaces. When choosing, it is worth proceeding from the optimal compromise between these characteristics. For example, a large tube length (up to 2 m in some models) is useful when processing fruit trees, but for a greenhouse it is better to choose a shorter sprayer. It is also worth considering that some sprayers use telescopic (sliding) tubes, the length of which can be adjusted as needed; in such cases, the unfolded size of the atomizer is usually indicated.

Operating time

Time of continuous operation of the battery sprayer (see "Type") on one battery charge. The actual operating time may differ slightly from the claimed one due to the specifics of a particular situation, however, these differences are usually not very large, and this indicator can be used to evaluate not only theoretical, but also practical indicators of battery life.

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.

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.
