16L 3 in 1 Knapsack Sprayer With Foaming and Misting Function

Who This Product Is For

This 16L 3 in 1 Knapsack Sprayer With Foaming and Misting Function targets professional end‑users including farm operators, orchard crews, greenhouse managers, sanitation service teams, commercial cleaning contractors and global product distributors. Instead of purchasing separate devices for spraying, fogging and foam washing, operators can finish multiple tasks with one single unit to cut equipment investment and simplify on‑site tool management.

Core Working Principle

Built with dual‑pump hardware: independent diaphragm water pump plus dedicated air pump. One‑touch mode switching enables three distinct outputs without extra tools or complex modification.

1.Foam output: Activate both pumps with cleaning agent added, generate dense foam for vehicle wash and surface deep‑cleaning

2.Fine mist output: Activate both pumps without detergent, produce ultra‑fine fog for disinfection, pest control, dust suppression and epidemic prevention

3.Standard spray output: Activate water pump only, operate as traditional backpack sprayer for plant watering and general cleaning

Crosstec 3‑in‑1 VS Ordinary Backpack Sprayer

Key Functional Highlights

Gun‑Mounted Bluetooth Remote Control

Bluetooth remote is fixed on high‑pressure spray gun and communicates exclusively with sprayer main host. Smartphone pairing is not available. Six‑speed flow adjustment lets operators change output directly at lance, no need to return to backpack unit during continuous field work.

18V DeWalt Slide‑Pack Battery Compatibility

Reuse your existing DeWalt 18V power‑tool batteries. No exclusive battery or extra charger purchase required. A 5.2Ah battery delivers up to 5‑hour continuous spray runtime. Integrated over‑discharge protection extends service life for both battery and pump assembly. Rotate spare batteries for all‑day non‑stop field work.

Patented Constant‑Pressure Output

Intelligent electronic control maintains steady pressure 1.0‑6.5 bar throughout battery discharge cycle. Uniform droplet size and consistent atomisation are guaranteed from full tank until liquid runs out, avoiding uneven application caused by voltage drop.

Heavy‑Duty 16L Chemical‑Resistant Tank

Constructed from impact‑resistant modified polypropylene. 16‑litre capacity balances comfortable backpack carrying and sufficient liquid volume. Tank material tolerates fertilisers, pesticides, disinfectants and cleaning detergents for mixed‑use jobs.

Self‑Cleaning Mechanism

One‑touch self‑cleaning cycle flushes chemical residue inside pump and pipelines after use, minimising blockage risk and lowering daily maintenance workload.

Why Partner With Crosstec

Since 2017, Crosstec has specialised in lithium‑powered sprayer R&D at a time when most competitors still relied on lead‑acid battery solutions. Our sprayers are supplied to distributors and OEM partners across more than 50 countries, deployed for vineyards in France, citrus orchards in Brazil, vegetable plantations across Southeast Asia and sanitation projects in the Middle East.

We have accumulated rich practical experience adapting products for variable local water quality, diverse agrochemical formulas and regional operator habits. Our proprietary constant‑pressure technology solves the common pain point of falling pressure when battery power decreases.

Every unit goes through complete full‑function factory inspection rather than spot‑check sampling, greatly reducing DOA product complaints for distribution partners. Custom logo, packaging and parameter tuning are supported for OEM and private‑label cooperation.

Customer Feedback

“We switched to Crosstec sprayers for our vineyard operations last season. The auto‑cleaning feature alone has saved our crew at least 30 minutes per day in maintenance time — over a 3‑month spraying season, that's a significant reduction in labor costs. The variable speed control also lets us adjust output for different vine densities without changing nozzles.”

Frequently Asked Questions

Q1: What differentiates this 3‑in‑1 sprayer versus regular backpack sprayers?

A1: This unit adopts dual‑pump setup supporting foam cleaning, fine fog disinfection and conventional liquid spraying. It features spray‑gun‑mounted Bluetooth remote which only pairs with sprayer host (no mobile phone connection), offering six‑gear on‑site flow adjustment. It also includes built‑in self‑cleaning and constant‑pressure functions missing on most ordinary sprayers.

Q2: Can I utilise my existing DeWalt batteries?

A2: Yes, compatible with standard 18V DeWalt slide‑in battery packs. 5.2Ah battery is recommended for maximum runtime. Send battery photos for pre‑order compatibility confirmation if you have doubts.

Q3: What liquids are safe to fill in the 16L tank?

A3: Compatible with fertilisers, herbicides, pesticides, disinfectants and detergents. It supports detergent mixing for foam generation and plain chemical liquid for fogging or regular spraying.

Q4: What is the maximum spraying distance?

A4: Exceeds 8 metres under correct nozzle configuration and proper operating conditions.

Q5: Do you accept wholesale and OEM private‑label orders?

A5: Yes. We deliver OEM projects for global distributors. Custom branding, packaging and specification adjustments can be completed according to market requirements.
