2.Product Overview

Field operators using conventional backpack sprayers constantly interrupt their workflow to bend down and tweak flow knobs on the tank body. This 15L Professional Bluetooth-Handle Backpack Sprayer wastes valuable working time and increases physical strain for long-hour orchard, farm and sanitation assignments.

Developed for professional agricultural contractors, commercial landscapers and disinfection service teams, this 15L Professional Bluetooth-Handle Backpack Sprayeradopts independent wireless Bluetooth communication between spray gun and main unit. All operation controls are concentrated on the spray gun handle, without smartphone connection or App operation. Compatible with DeWalt 18V lithium batteries and equipped with a high-stability diaphragm pump and heavy-duty 15L chemical-resistant tank, this equipment is highly favored by global agricultural equipment wholesalers, importers and OEM partners for crop protection, vineyard management and commercial sanitization projects.

3.Core Product Advantages

Wireless Bluetooth Gun Handle Remote Control

The spray gun connects wirelessly to the main machine via built-in Bluetooth module. Operators can switch start/stop and adjust flow rate directly by pressing physical buttons on the gun handle while walking, without halting work or bending toward the tank.

Vibration reminder and buzzer feedback enable reliable blind operation, even when users wear thick protective gloves or work with wet hands. Multiple flow parameters can be locally stored for one-click switching to satisfy varied spraying requirements for different crops and environments. No mobile phone, application software or display screen is required during whole operation.

Universal Compatibility for DeWalt 18V Lithium Batteries

End-users can reuse their existing DeWalt 18V power tool batteries to power this sprayer. There is no necessity to purchase exclusive matched batteries separately, which effectively lowers procurement costs for professional working crews and equipment rental businesses. Stable power supply ensures long continuous spraying time for large-area outdoor operations.

Heavy‑Duty Diaphragm Pump Assembly

The robust diaphragm pump delivers consistent working pressure and fine uniform atomization. It is compatible with diluted pesticides, liquid fertilizers and a variety of disinfectant solutions. Compared with ordinary pump structures, it needs less routine maintenance and maintains stable performance under heavy‑duty all‑day field conditions.

Robust 15L Industrial Polypropylene Liquid Tank

The 15-liter tank is injection molded from high-strength polypropylene raw material. It features outstanding chemical corrosion resistance, anti-ultraviolet aging performance and reliable leak-proof structure. Reasonable capacity design reduces frequent liquid refilling, perfectly matching medium and large-scale farming and commercial sanitation tasks.

Optimized Ergonomic Backpack Carrying System

Thickened padded shoulder straps and breathable contoured back cushion reasonably distribute equipment weight. It greatly alleviates shoulder and back fatigue caused by long-time carrying. The humanized back frame fits different body shapes and significantly improves comfort during all-day outdoor spraying work.

4.Application Fields

* Pest and disease control for fruit orchards, vineyards and large plantations

* Liquid fertilizer application and seedling care inside greenhouses

* Landscape maintenance for gardens, lawns and shrub zones

* Sanitization and disinfection for public areas and commercial premises

5.Operating Steps

One-Touch Preset/Memory Function (Advanced Models)

Some Bluetooth handles support two or three preset settings, for example:

Short press "+"  : stepwise flow increase

Long press "M"  : save current flow as preset

Double press "M"  : switch to preset mode
