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

Battery-Powered Precision for High-Volume Spray Applications

The Jacto PJB16 is a leading innovator among battery-powered backpack sprayers. 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 for finer droplets.
• 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: Keeps 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.
• Auto Shut-Off and Lockable Pressure: Pump activates automatically when pressure drops and shuts off when spraying stops.

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, 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. Always verify chemical compatibility with the product label before use.

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. This 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 that produce larger, drift-resistant droplets, while insecticides and fungicides need finer droplets at higher pressures for canopy penetration.

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; when you close the lance, pressure builds and the pump shuts off, conserving battery life.

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

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