HITACHI 20L Battery-Powered Knapsack Sprayer

HITACHI 20L Dual-Operation Knapsack Sprayer (Rechargeable Battery & Manual Pump) for Heavy-Duty Use

Pesticide spraying and facility biosecurity demand ultra-reliable equipment that never stalls mid-operation.
A depleted battery in the middle of an agricultural plot or poultry house can halt an entire workday and waste pre-mixed chemical batches.
The HITACHI 20-Liter Dual-Operation (2-in-1) Sprayer is engineered specifically to eliminate downtime entirely, combining the effortless speed of an automatic electric motor with the failsafe reliability of an emergency manual hand pump.
The unit features a heavy-duty 20-liter high-density polyethylene reservoir, allowing operators to cover expansive acreage without frequent refilling stops.
In electric mode, the intelligent high-pressure pump runs off a dedicated rechargeable battery, generating a fine, uniform mist that penetrates dense foliage and difficult angles with minimal chemical runoff.
Should the battery run out in remote fields far from a power outlet, the integrated side-pump lever enables instantaneous switchover to manual pumping—keeping operations moving seamlessly without disruption.
Whether sourcing a versatile hybrid knapsack sprayer in Egypt or outfitting poultry operations, greenhouses, and commercial facilities with a dependable sanitation unit, the HITACHI 2-in-1 sprayer is a rugged investment pairing ergonomic weight distribution, UV/chemical-resistant polymers, and complete protection against unexpected battery drain.

4. Tool-Free System Transition: Smooth, responsive manual hand lever operates seamlessly without requiring disassembly or additional tools.

5. Chemical & UV-Resistant Shell: Built from heavy-duty plastics that endure harsh outdoor conditions, aggressive pesticides, disinfectants, and prolonged UV exposure.

6. Ergonomic Weight Balancing: Broad, cushioned harness straps and a back-molded contour stabilize liquid payloads to minimize physical operator fatigue.

7. Quick Field Serviceability: Modular filters, hose unions, and nozzle assemblies disassemble effortlessly for field cleaning and unclogging.

Target Applications & Operating Environments

• Agricultural Fields & Orchards: Broadcast application of insecticides, fungicides, herbicides, and liquid foliar fertilizers across open-field crops and fruit trees.

• Greenhouses & Nurseries: Delicate seedling care and target spraying using finely atomized mist patterns that protect soil beds and fragile blooms.

• Pest Control & Vector Management: Structural perimeter treatments, termite soil barriers, bed bug eradication, and cockroach control in warehouses, villas, and gardens.

• Poultry & Livestock Housing: Routine biosecurity washdowns, sanitizing broilers and laying sheds, and parasite control in animal farming operations.

• Industrial Facilities & Logistics Hubs: Equipment degreasing, wide-area detergent applications, and deep floor sanitization across exterior docks and yards.

• Public Venues & Civic Buildings: Disinfecting schools, places of worship, hospitals, and transit hubs quickly and efficiently.

Directions for Safe & Optimal Operation

1. Pre-Operation & Charging: Charge the onboard battery fully using the included charger before deployment, and verify that the manual lever linkage is securely fastened.

2. Solution Mixing & Filling: Pre-mix treatment chemicals in a separate vessel and pour through the top basket filter to catch unmixed solids or environmental debris.

3. Mounting & Harness Adjustment: Fasten the threaded tank cap securely. Hoist the unit onto your back and adjust both padded shoulder straps for a balanced, snug fit.

4. Electric Operation: Flip the sealed rocker switch to ON, squeeze the lance handle trigger, rotate the brass nozzle to calibrate droplet spray, and proceed with application.

5. Manual Lever Transition: If the battery depletes mid-task, switch the electrical power OFF, grasp the lateral manual pump handle, stroke the lever to build operating pressure, and resume spraying without pausing the job.
