Knapsack Sprayers Buying Considerations
There are plenty of things to keep in mind before deciding on the best knapsack sprayer for you. To start, be sure you understand the space you’ll be treating so that you can better choose which is the best knapsack sprayer for you.
There are a few different types of knapsack sprayers available, some more popular than others. The type you choose will depend on the area you are trying to service along with the features you want to ensure comfortability while using the sprayer.
This are often the most popular version of knapsack sprayer. You need a hand pump with these and as you pump, the liquid in your sprayer moves into the wand to be sprayed.
These are popular, in large part, because they are relatively inexpensive. When compared to motorized sprayers, they are simply more affordable. However, these can absolutely cause hand fatigue, especially if you are hoping to cover a large area or plan on using it for a long period of time.
Manual knapsack sprayers are ideal for smaller spaces. One final consideration when purchasing a hand pump or manual sprayer is that many will include a locking mechanism. That mechanism allows for a continuous spray of liquid, effectively saving your hand from fatigue.
These sprayers are intended for use in larger areas. They allow you to work quickly, which means you can more easily cover bigger spaces. You won’t have any fatigue or pressure in your hands when using this type of knapsack sprayer.
The downsides to these sprayers is that they are heavier than their manual alternatives. They also cost a lot more and require more maintenance.
Powered sprayers can accommodate and hold more liquid than the manual alternative and typically comes with or uses more attachments.
Types of Nozzles
The nozzle is one of the most important features on your knapsack sprayer. They are integral to the overall performance of the tool, despite the fact that they are pretty inexpensive. Many knapsack sprayers will come with various nozzles while some will come with just one.
Nozzles are what meter the amount of herbicide or pesticide that you are using, and they regulate the rate of application as well. They also control the spray’s variability and the droplet size.
There are two different types of cone sprays. They are full cone and hallow cone. The full cone uses a circular pattern for spraying while the hallow cone makes a ring-shape.
Full cones offer coarse drops of liquid in larger amounts when compared to the hallow cone.
This nozzle makes an inverted, narrow letter V. It typically produces an even, uniform distribution of liquid by creating a flat spray. The drop size is large and has a medium velocity. The impact with this spray is high when compared to other patterns.
This nozzle is most often used for the application of fertilizer. This particular nozzle pattern means that you are less likely to get leaf burn, allowing the soil to more fully absorb the liquid being applied.
You can really ease the amount of work you have to do in your garden and lawn by investing in a good backpack sprayer. Hopefully, this guide and product comparison has highlighted the best knapsack sprayer for your particular needs.
