15L Portable Electric Agricultural Sprayer

Practical battery‑powered knapsack sprayer with Bluetooth‑equipped spray‑gun handle, built for daily professional plant‑protection and sanitization work。

Product Overview

This 15L Portable Electric Agricultural Sprayer is a battery‑driven spraying device designed for orchards, greenhouses, landscape maintenance and commercial disinfection work. Its main difference from conventional electric backpack sprayers lies in the Bluetooth‑connected spray gun handle: flow rate adjustments can be operated directly on‑handle instead of adjusting knobs on the sprayer main body。

It adopts a diaphragm pump and 15‑litre chemical‑resistant tank together with padded backpack harness. Suitable for distributors, contractors and OEM purchasers looking for practical upgraded battery spray equipment. Bluetooth function works between spray gun handle and main unit, it does not support mobile‑phone APP remote control.

Core Product Features

Bluetooth‑Connected Spray‑gun Handle

The spray gun handle connects wirelessly to the sprayer unit via Bluetooth module. Adjust flow by pressing +/- buttons on the handle while walking, no need to stop work and bend down to twist the knob located on the sprayer body。

*Buttons can be operated while wearing thick protective gloves

*Vibration and beep sound offer operation feedback when pressing buttons

*Handle‑mount Bluetooth module needs regular charging (approx. one‑week runtime per full charge)

*Advanced version supports saving 2‑3 commonly‑used flow presets for quick switching

Note: Bluetooth signal may be interfered under dense foliage or strong electromagnetic environment, keep reasonable distance between spray gun and main machine.

Variable‑Flow Diaphragm Pump System

Industrial‑grade diaphragm pump supplies steady output pressure during continuous operation. Flow can be adjusted in steps to match different crops and liquid formulations, helping reduce unnecessary chemical consumption and get relatively even spray coverage.

*Maintain stable atomization status during most working conditions

*Suited for long‑hour intermittent professional spraying work

*Actual spray effect still depends on nozzle selection, liquid mixing ratio and operating habits of end‑users

15‑Litre Chemical‑Resistant Tank

Tank is made of thickened polypropylene material, with resistance against common pesticides, herbicides, liquid fertilizer and disinfectant liquid, as well as UV ageing for outdoor use.

*Visible liquid‑level scale marks on tank side

*15L capacity cuts down refill frequency for medium‑large working areas

*Not applicable for strong corrosive solvent‑based liquids.

Practical Backpack Carrying System

Adjustable shoulder straps and thick breathable back padding distribute weight when the tank is filled. Backpack structure fits long‑time field operation and reduces body burden to a certain extent; actual comfort varies with operator’s body type and total liquid load weight.

Bluetooth‑Handle VS Traditional Body‑Mount Knob

Suitable Application Scenarios

This sprayer can handle water‑soluble pesticides, herbicides, foliar liquid fertilizers and water‑based disinfectants. Common applicable places as follows：

*Fruit orchards & vineyard plant protection

*Vegetable greenhouses and farmland spraying

*Landscape and garden maintenance work

*Public‑area cleaning and sanitization projects

*Forestry small‑plot plantation management

Not recommended for high‑viscosity undiluted stock solutions and strong‑corrosive chemical solvents.

Runtime & Practical Notes

*Continuous working time changes with battery capacity, flow setting and actual pressure. Real‑world continuous working range is approx. 1.5‑10 hours, figures are for reference only, not fixed guarantee value.

*Lithium battery performance will decline under extreme high‑temperature or low‑temperature outdoor environment.

*Bluetooth connection might become unstable under heavy shielding environment, restore connection by short power‑cycle if disconnection occurs.

Frequently Asked Questions

Q1: Can I control this sprayer via mobile phone Bluetooth APP?

A: No. Bluetooth function only realizes signal communication between spray‑gun handle and sprayer main unit, there is no mobile‑phone APP connection function.

Q2: Does the Bluetooth‑handle completely avoid stopping work during adjustment?

A: Under normal signal condition you can adjust flow without pausing spraying. In case of signal loss you still need to reset or use backup adjustment way.

Q3: What liquid can I pour into the 15L tank?

A: Fit for most water‑mixed agricultural chemicals, liquid fertilizer and water‑base disinfectant. Avoid undiluted strong‑corrosive solvent liquid to prevent tank and pump damage.

Q4: How long can battery last for one full charge?

A: Working duration is related to flow setting. Higher flow consumes power faster. The 1.5‑10‑hour data is practical reference range, cannot be treated as fixed‑spec parameter.

Q5: Is OEM and private‑label service available?

A: Yes, we provide OEM & ODM service including logo printing, customized box packaging and colour matching, subject to minimum order quantity requirements.
