Volume
The nominal volume of the sprayer tank. Usually, in this case, the working volume is indicated, and not the full capacity (“for the cork”).
The more capacious the sprayer is, the more work can be done with it without refueling. On the other hand, a large volume accordingly affects the price, dimensions, and most importantly, the weight of the unit (and not only in a filled, but also in a “dry” state). Therefore, even with large volumes of work, it is sometimes more rational to use a relatively small unit, refueling it several times.
Detailed recommendations on the optimal volume of the tank for a particular situation can be found in special sources. With regard to specific values, in the most compact manual sprayers (see above), the capacity
does not exceed 2 liters. Tanks for
2.1 – 5 liters can be found both in hand-held devices, and in pump-action and battery models (see "Type") with a shoulder carry. Sprayers for
5.1 – 10 liters are almost all made shoulder-mounted, the capacity of gasoline units actually
starts from 10 liters, and the most capacious modern sprayers have tanks
of more than 15 liters.
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.
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.
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.
