Designed for orchard growers, farm contractors, sanitization companies, and professional gardeners, the 15L Knapsack Sprayer with Self-Cleaning delivers high-efficiency spraying performance with industrial-grade reliability. Manufactured by Crosstec, this model integrates a diaphragm pump system, constant pressure control, and Dewalt 18V battery compatibility for maximum operational flexibility.
This sprayer is compatible with standard 18V DeWalt battery platforms, allowing users to operate the unit using batteries commonly used for drills, impact drivers, and other power tools. It eliminates the need for a dedicated sprayer battery system.
Battery specification: 18V / 2.6Ah (battery not included)
Typical runtime: approximately 4–5 hours depending on flow setting and workload.
The built-in self-cleaning function helps reduce internal residue buildup during operation. This supports more stable performance when using fertilizers, pesticides, and soluble powders.
The system helps reduce clogging risk and minimizes routine maintenance compared with standard sprayers.
The sprayer is designed to maintain consistent pressure output during operation, improving spray uniformity across different battery levels.
Users can adjust flow output to match different applications, from fine misting for seedlings to stronger spray patterns for orchard and field use.
The 15-liter tank is designed for balanced capacity and portability in daily agricultural and gardening tasks.
It is made from impact-resistant polypropylene material with resistance to common agricultural chemicals and UV exposure, suitable for extended outdoor use.
