The 12 liter plastic tank has a wide viewing window for checking the fill level, and it also has a wide filling opening with an integrated sieve. Not only does this make it easier to fill the tank, it also prevents solids from accidentally getting into the tank.

Purchase criteria

material

Sprayers, which also include the backpack sprayer, need a tank. This should be made of sturdy plastic, as it has to withstand a lot depending on its filling capacity and pressure. If acidic or caustic liquids are to be sprayed, attention must also be paid to the use of specially approved materials. The spray lance, in turn, should be made of metal (e.g. B. Brass) and not made of plastic. Experience has shown that plastic lances break faster.

Capacity

Backpack sprayers are not carried on their backs for nothing, because their tanks are usually much larger than those of smaller pressure sprayers, with a capacity of at least 12 to 16 liters. Therefore, these devices are very suitable for working on larger lawns or other plantings such as one Orchard meadow. In addition, you can use them not only in the garden, but also for other activities. A sprayer with a large tank is also suitable for cleaning work, e.g. B. the terrace, the driveway, the garden paths, the car, etc. It is therefore an advantage if you do not have to constantly refill thanks to the large tank.

Empty weight

But be careful: the more the tank holds, the heavier the backpack splash, especially when it is full. It is therefore essential to pay attention to the curb weight, which should not exceed three kilograms if possible. When filled, such a device with a 12-liter tank weighs around 15 kilograms - you have to be able to carry it first. However, the empty weight should not be too low, as this can be an indication of inferior (i.e. too thin) plastic.

Operating mode and pressure

Many sprayers, especially in the cheaper price ranges, work with a hand-operated pump, i. H. You have to build up the pressure yourself with a hand pump. This can be quite exhausting in the long run, which is why you can retrofit some models (e.g. from the comfort range from Gloria) with a compressor. This pumps the pressure tank to the required working pressure within a very short time without any effort. Other backpack sprayers also work with a battery, which, however, only lasts for a limited time and has to be recharged again and again.

Atomization and setting

In order to be able to apply fertilizer and other liquids effectively, the backpack sprayer should be adjustable to different degrees of atomization. This works either with adjustable nozzles or by exchanging them. The intensity of the spray mist, in turn, is controlled via the tank pressure. A fine spray mist is ideal for spraying fertilizers and pesticides, as it is more evenly distributed. For cleaning work, however, a powerful jet is recommended.

Spray lance

The length of the spray lance is also an important purchase criterion. After all, you want to apply the liquids precisely where they are supposed to - and that without having to bend down all the time. Working upright is important for ergonomic reasons alone, so that you do not suffer from back pain afterwards. Make sure that the spray lance is at least 50 centimeters long. Telescopic models that can be extended if necessary are also best. Most manufacturers, however, offer special spray lance extensions for their devices that must be purchased separately.
