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. fluid temperature

The maximum fluid temperature that the sprayer can safely handle.

The preparation process of some formulations requires heating; therefore, data on the temperature to which the liquid must cool can be very important for safe operation. However, even in the most heat-resistant sprayers, this figure does not exceed 40 °C; such a liquid feels warm to the touch.

It is worth remembering the temperature limits when the unit is in the sun: if the tank has had time to get very hot in the sun, you should let it cool down before starting work.

Replaceable nozzles

The ability to change nozzles — sprayer working nozzles.

Different nozzles differ primarily in terms of spraying distance and width of the plume, as well as the degree of spraying (particle size). In addition, specific nozzles can be used in sprayers — for example, for working with powder. Replacement nozzles are usually included in the delivery, but this point (as well as the range of nozzles) is still worth clarifying separately.

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.
