Comparison Foresta GS-750 Turbo vs Forte 3WF-3

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.

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.

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.

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.

The volume of one cylinder in an internal combustion engine installed in a sprayer. In fact, we are talking about the working volume of the entire engine, because. in this technique, only single-cylinder internal combustion engines are used.

In general, a large cylinder volume allows you to achieve high power, but power also depends on some engine characteristics (primarily the type of internal combustion engine, see above). And the performance characteristics of the sprayers themselves with the same engine power can also be different. But what directly depends on the volume of the engine is fuel consumption: a larger volume, usually, requires more fuel.

Engine power of the gasoline sprayer (see "Type") in horsepower.

Power directly affects the spraying range and the performance of the unit, according to this indicator, it is quite possible to assess the overall level of the device. However note that manufacturers can indicate this characteristic in different ways: some give the rated power (when the engine is running in normal mode), others give the maximum power (at peak load). Therefore, when choosing and comparing, it is worth considering not only this indicator, but also other basic characteristics.

As for horsepower, this unit is traditionally used to assess the power of an internal combustion engine. 1 HP approximately equal to 735 watts.

Sprayer engine power in kilowatts. Watt (kilowatt) is a universal unit used for all types of engines, but in fact this parameter is indicated mainly for gasoline units (see "Type"). This is due to the fact that electric sprayers — even the most powerful and heavy ones — consume less than 1 kW, which does not create any problems with connecting to a conventional outlet; so for such units there is no need to specify engine power.

Power directly affects the spraying range and the performance of the unit, according to this indicator, it is quite possible to assess the overall level of the device. However note that manufacturers can indicate this characteristic in different ways: some give the rated power (when the engine is running in normal mode), others — the maximum (at peak load). Therefore, when choosing and comparing, it is worth considering not only this indicator, but also other basic characteristics.

As for specific figures, in the most modest models this figure does not exceed 1 kW ; 1.1 – 2 kW can be called the average value; and many gasoline sprayers are equipped with motors and more than 2 kW.

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.

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.
