Know before you buy
Yes, the sprayer is equipped with durable Viton seals, which are highly resistant to a wide range of common herbicides, fungicides, and fertilizers. Always rinse the tank thoroughly between different chemical applications to prevent cross-contamination.
Absolutely. The sprayer features an ambidextrous pump handle design, allowing you to easily configure it for either left- or right-handed operation based on your preference.
This model includes a built-in three-stage filtration system specifically designed to catch debris before it reaches the nozzle. This significantly reduces the risk of clogs, even when using liquid fertilizers.
Adjustable pressure (15-60 psi) allows you to control the spray pattern and intensity. Lower pressure is ideal for delicate plants or spot treatments, while higher pressure provides the reach and force needed for larger areas or taller foliage.
The sprayer is designed with ergonomics in mind, featuring padded shoulder straps and a waist strap to help distribute the weight of the 4-gallon tank evenly across your back and hips, reducing strain during extended use.
When using the appropriate pressure, the sprayer can reach up to 25 feet horizontally and 23 feet vertically. Keep in mind that actual distance can vary based on the nozzle type selected and the viscosity of the liquid being sprayed.
