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.

Productivity (powder)

Maximum performance of the sprayer when working with powder (if the appropriate mode is available, see below). On pump (see "Type of pumping") and cordless (see "Type") models, 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 "weak" sprayer will just take longer to process, and a too powerful one 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.

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.
