Comparison Gartner GBS-10/12 vs Gartner GBS-16/12 MP

General type of sprayer. Nowadays, there are mainly such options: pump action, lever, gasoline, battery(classic and hybrid) and electric(network). Here is a more detailed description of each variety:

— Pump. One of the varieties of sprayers that work on the user's muscular strength — along with lever ones. The difference lies in the fact that in this case the accumulative principle is used: with the help of a pump, a supply of compressed air is pre-inflated into the tank, which is gradually consumed during operation; the stock needs to be replenished from time to time by pumping up the pump. A characteristic external sign of a pump-action sprayer is the paging handle located in the upper part; Because of this, shoulder-carrying models (see "Design") have to be worn on one shoulder so that the handle remains within reach. This is somewhat less convenient than carrying lever models on two shoulders; on the other hand, one hand remains free when working with this type of shoulder sprayer. And the common advantage of all pump units is that during operation it is not necessary to constantly pump air. On the other hand, this design is poorly suited for more or less large volumes, so the tank capacity in this type of atomizers does not exceed 12 liters.

— Lever....Another type of sprayers that use the muscular strength of the operator to work. Such devices differ from pump-action models in that the pumping lever must be pumped constantly — each movement of it sends a portion of liquid to the nozzle. This can be quite tedious, however, lever sprayers have their advantages. Firstly, they are simpler, cheaper and at the same time more reliable and safer: damage to the tank does not lead to an “explosion” with splashing of the contents, and the performance of many models is maintained even with a leaky tank. Secondly, large shoulder units of this type are usually carried on two shoulders, like backpacks — this ensures the most even distribution of the load; the pumping lever in such sprayers is installed on the side, most often under the operator's left hand.

— Rechargeable. Sprayers with electric pumps powered by batteries. This design eliminates the need for the operator to manually inflate air, reducing fatigue and making it easier to treat large areas. At the same time, battery models are easier and cheaper to operate than gasoline ones, they are quieter and do not produce exhaust gases; and their advantage over mains sprayers is their independence from sockets. Among the disadvantages of this option, one can note the limited operating time on a charge and the need for long breaks to charge the batteries; however, in some models this moment is compensated by the use of removable batteries, which you can have in stock a few pieces. Note that this type of power supply is best suited for shoulder-mounted models, although there are also wheeled and combined sprayers (see "Design") on batteries.

— Battery hybrid. Sprayers (usually shoulder-mounted, see "Design"), equipped with two pumps at once, with two separate drives — (usually lever, see above) and battery. Thus, such models combine the advantages of both types: the battery allows you to work without additional physical effort, and when the battery runs out, you can switch to manual pumping and continue working for as long as you need. At the same time, such capabilities are rarely required, and additional equipment significantly affects the price of the unit; therefore, there are few models of this type nowadays.

— Petrol. Sprayers driven by a petrol engine. The key advantages of such units are high power and performance, battery life (including complete independence from sockets), as well as good suitability for long-term work (both due to the “endurance” of the engines themselves and due to the speed of refueling). On the other hand, gasoline engines are more complicated and more expensive than electric ones (both by themselves and in operation), weigh more, make a lot of noise and produce exhaust gases. Therefore, such engines are installed mainly in heavy performant models designed for large volumes of work.

— Electric. Sprayers with electric motors powered by conventional sockets. With the same power, such units have less weight and cost than battery counterparts, and their operation time is practically unlimited. On the other hand, the need to pull the wire from the outlet significantly limits mobility. Therefore, this option has not received much distribution, it is found only in some wheeled models (see "Design"), where battery life was sacrificed for the sake of the advantages of an electric motor.

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.

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.

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.

Time of continuous operation of the battery sprayer (see "Type") on one battery charge. The actual operating time may differ slightly from the claimed one due to the specifics of a particular situation, however, these differences are usually not very large, and this indicator can be used to evaluate not only theoretical, but also practical indicators of battery life.

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.

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.

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.
