For example, we get calls from customers who want to use their existing sprayer and simply purchase a new spray gun to spray to further heights. Unfortunately, this is not how it works: the whole system needs to be adequate. If you don’t use the right tank, pump, spray hose or spray gun you won’t hit the desired distance.
Here are 3 important things to consider when spraying tall trees:
- Pick the right tank size - It's necessary for the tank capacity to be 5 - 6 times the max flow rate of the pump. We recommend the largest tank possible while still fitting space requirements. One of the main issues with using a tank that's too small is that the high flow rate of most pumps will empty a small tank quickly and create cavitation in the lines which leads to decreased performance.
- Pick the right pump, spray hose, and spray gun - In order to proper height when spraying tall trees, both flow and pressure are required. So a spray hose with with a diameter large enough that it does not restrict the flow of the liquid is essential. High pressure will atomize the droplets and allow them to reach increased heights.
- Wear appropriate personal protective equipment (PPE) - PPE protects the body from hazardous chemicals. To reduce the risk of harm or injury, professional spray applicators should wear face, eye, skin, and hand protection.
