4-gallon Lithium-ion powered backpack sprayer, built to outperform, outlast, and finish the job in less time - with no more pumping. The lithium-ion powered backpack sprayer has Variflo technology which allows the operator to adjust the flow for multiple applications using specific nozzles for consistent spraying. This sprayer has a deluxe harness with wide, padded shoulder straps that fit snuggly across the torso and curve to the contour of the users body. An adjustable hip harness assists with weight distribution, relieving burden from the users shoulders. Multiple nozzle tips are included for versatility in both application rates and patterns and can be stored on the included nozzle clip. Equipped with a comfort grip handle and lock-on mechanism, this shut-off system can be easily operated with heavy-duty work gloves. It includes a 50 heavy-duty nylon-reinforced hose and strain relief system preventing the hose from kinking at the chemical exit point. This sprayer unit is also equipped with chemically resistant Viton seals throughout to withstand the effects of harsh chemicals. Whether it's for weeding and feeding, disinfecting, finishing concrete, eliminating mold, or controlling pests - users are equipped for the job.
