Purchase Criteria
material
Sprayers, which include backpack sprayers, need a tank. This should be made of sturdy plastic, as it has to withstand a lot depending on the filling capacity and pressure. If acidic or caustic liquids are to be sprayed, it is also important to use materials specially approved for this purpose. The spray lance, on the other hand, should be made of metal (e.g. brass) and not plastic. Experience has shown that plastic lances break more quickly.
capacity
It is not without reason that backpack sprayers are carried on the back, because their tanks are usually significantly larger with a capacity of at least 12 to 16 liters than those of smaller pressure sprayers. Therefore, these devices are very well suited for processing larger lawns or other plantings such as an orchard. In addition, you can use them not only in the garden, but also for other activities. A spray gun 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 an advantage if you don't have to keep refilling thanks to the large tank.
curb weight
But be careful: the more content the tank holds, the heavier the back 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 that first. However, the curb weight should not be too low either, as this can be an indication of inferior (i.e. too thin) plastic.
operating mode and pressure
Many sprayers, especially in the lower price ranges, work with a hand-operated pump, i. H. You have to build up the pressure yourself with a hand pump. This can become quite exhausting in the long run, which is why you can retrofit some models (e.g. from the Comfort range from the manufacturer 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 via adjustable nozzles or by exchanging them. The intensity of the spray is in turn controlled by the tank pressure. A fine spray mist is ideal for spraying fertilizer and pesticides, as it is distributed more evenly. For cleaning work, on the other hand, 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 go - and without having to constantly bend down. Working upright is important for ergonomic reasons alone, so that you do not suffer from back pain afterwards. Therefore, make sure that the spray lance is at least 50 centimeters long. Telescopic models that can be extended if necessary are also best. However, most manufacturers offer special spray lance extensions for their devices, which must be purchased separately.
