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.
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.
Telescopic wand
Availability of a folding
telescopic tube in a set of delivery of a sprayer.
The length of such a tube can be adjusted within certain limits, adjusting it to the specifics of the situation. For example, in cramped conditions, a large length is not needed, but when processing tall trees, on the contrary, it is very convenient. Specific adjustment options may be different: in some models, you can choose only one of the two extreme positions (fully folded or fully unfolded), while others allow you to fix the handset in intermediate positions.
Wand holder
The presence
of a tube clamp in the design of the sprayer.
Such a latch is a set of special clips, usually installed directly on the tank. It greatly simplifies the storage and transportation of the device: the handset, usually, is placed as compactly as possible and at the same time securely. Yes, and during breaks in work, this feature can come in handy — fixing the tube in the retainer is more convenient and safer than putting it on the ground, holding it in your hands, etc.
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.
