Product Features

1. 16L Large-Capacity Tank

The large tank reduces the frequency of refilling, making it suitable for operations in large fields, vegetable gardens, and orchards. The thickened PP plastic tank is resistant to aging and chemical corrosion (acid/alkali) and is highly durable against cracking.

2. Manual Pressurization - No Power Constraints

Operated entirely by manual air pressure, it requires no batteries or power cords, allowing for use in remote fields or areas without electricity. Simply pump the handle to pressurize the tank for continuous spraying; operation is straightforward.

3. Ergonomic Knapsack Design

The dual-shoulder strap design distributes weight across the back, reducing hand fatigue during prolonged use. The tank is contoured to fit the back comfortably, making it easy to carry and move.

4. Adjustable Spray Wand and Controllable Trigger

The long spray wand allows for flexible adjustment of spraying height and distance. The trigger switch enables instant start/stop control, allowing the user to regulate the spray as needed. It can deliver either a concentrated stream or a fine mist to meet various spraying requirements. 5. Simple assembly and easy maintenance

4. Do not over-pressurize the unit to avoid hazards caused by excessive internal pressure; do not spray towards people or animals.

5. Clean promptly after use to prevent chemical residue from corroding hoses or causing clogs; store in a cool, dry place out of the reach of children.
