Key Features
- Heavy-Duty 304 Stainless Steel Construction: Rust-resistant and built for long-term durability. Ideal for most commercial liquid fertilizers and general-purpose spraying. Note: rubber components are not suited for highly corrosive, strongly acidic, or strongly alkaline solutions.
- Adjustable Brass Nozzle: Effortlessly switch between a focused jet stream and a fine mist spray — adapting instantly to the task at hand, from targeted watering to broad-coverage cleaning.
- Generous Capacity: 10-liter working volume (13-liter total tank) means fewer refills and more time getting the job done.
- Ergonomic Hand Pump & Shoulder Strap: The large-flow piston rod and ergonomic handle allow you to build operating pressure quickly and easily. The adjustable padded shoulder strap makes carrying the full tank comfortable during extended use.
- Integrated Safety Valve & Pressure Gauge: Monitor internal pressure in real time with the built-in gauge (1.5–4.0 bar operating range). The automatic safety valve releases excess pressure to keep operation safe and consistent.
- Extended Reach: Includes a 51 cm (20.1 in) lance and a 91.4 cm (3 ft) reinforced hose, giving you impressive reach for high or hard-to-access areas.
- Easy Fill Design: Bowl-shaped water inlet makes topping up the tank quick and splash-free.
