Jacto PJB16 Battery Backpack Sprayer - 4gal - Lithium-Ion

Jacto PJB16 Battery Backpack Sprayer - 4gal - Lithium-Ion

The Jacto PJB16 is the most innovative battery-powered backpack sprayer in its class. A long-life lithium-ion battery powers a high-output diaphragm pump rated at 0.61 GPM - nearly 60% more flow than comparable competitors. Five selectable pressure settings give you precise control over droplet size for herbicides, insecticides, and fungicides, while the in-tank Venturi agitator keeps wettable powders and agrichemicals in suspension throughout the application.

Key Features & Benefits

• 5 pressure settings: Select low pressures for herbicides to minimize drift, or higher pressures for insecticides and fungicides to achieve finer droplets and improved canopy coverage.
• High-output 0.61 GPM pump: Diaphragm pump delivers nearly 60% more flow than competing battery backpack sprayers - covering more area per charge.
• Venturi in-tank agitator: The only battery-powered backpack sprayer with a Venturi agitator to keep wettable powders and agrichemicals in solution - even with the sprayer on your back.
• Digital display and soft-touch controls: Monitor battery level, pressure setting, and pace meter at a glance with intuitive controls.
• Auto shut-off and lockable pressure: Pump activates automatically when pressure drops and shuts off when spraying stops - lockable setting maintains consistent pressure.
• Suction filter pump protection: Internal suction filter protects the pump from impurities and clogging during use.

Who Should Use This

The Jacto PJB16 is the go-to choice for growers, landscapers, and commercial applicators who need battery-powered precision for high-volume spray applications. The 5-pressure selection system makes it equally effective for low-drift herbicide applications and fine-mist fungicide treatments - all without the noise, fumes, or fuel costs of a gas-powered sprayer.

Compatibility

Suitable for water-based herbicides, insecticides, fungicides, wettable powders, and other agrichemicals in a 4-gallon format. The Venturi agitator is especially valuable for wettable powder formulations that require constant agitation to stay in suspension. Always verify chemical compatibility with the product label.

Frequently Asked Questions

How does the Venturi agitator work?

The in-tank Venturi agitator uses pressure differentials in the liquid flow to create a circulation current inside the tank, keeping wettable powders and other formulations continuously mixed throughout the application. It is the only battery backpack sprayer technology of its kind and is especially valuable for agrichemicals that settle quickly.

Why are 5 pressure settings important?

Different chemicals and applications require different operating pressures. Herbicide applications benefit from lower pressures to produce larger droplets that resist wind drift, while insecticides and fungicides require finer droplets at higher pressures for effective canopy penetration and coverage. The PJB16's 5-setting system covers the full range of professional spray applications.

How does the auto shut-off pump work?

An internal micro pressure switch monitors line pressure. When you open the spray lance and pressure drops, the pump activates automatically to maintain your selected setting. When you close the lance, pressure builds and the pump shuts off - conserving battery and preventing over-pressurization.

How does the pump flow compare to other battery backpack sprayers?

The Jacto PJB16's diaphragm pump is rated at 0.61 GPM, which is approximately 60% higher than the average competing battery backpack sprayer. This translates to faster coverage, less time in the field per tank load, and more efficient use of battery charge per acre treated.
