The 3WF-3 Backpack Fogger is a high-capacity tool powered by a 2.13kw gas engine, designed for demanding tasks in vegetable sheds, orchards, and large urban green spaces. It features a 3.7-gallon HDPE tank that provides a significant amount of treatment volume, reducing the need for frequent refills. The engine provides a horizontal spray range of approximately 10 to 12 meters, allowing for much greater reach than most electric or manual alternatives.
This unit is versatile, as it can function as both a chemical sprayer and a high-velocity leaf blower. The engine utilizes a standard 2-stroke fuel mix (typically 25:1 or 50:1), and using high-quality fuel helps maintain the carburetor gaskets over time. To ensure comfort during longer tasks, the unit includes harness straps, though users should be mindful of the weight distribution as the 3.7-gallon tank empties.
Practical steps for longevity include flushing the reinforced PVC nozzle assembly after every use to prevent clogs. While the unit is built for heavy use, checking the mounting points between the engine and the tank periodically is a good maintenance habit. This ensures that the vibration-dampening components are performing as expected and the chassis remains secure.
If you need a lighter, more compact solution for smaller yard tasks that doesn't require mixing gas, the Black Flag 190095 is a portable propane-powered alternative.
