16L 3 in 1 Backpack Sprayer With Foam Mist and Spray Modes

Many field operators need multiple separate devices for foam washing, fog disinfection and conventional crop spraying, raising procurement cost and tool management burden. Crosstec’s 16L 3 in 1 Backpack Sprayer With Foam Mist and Spray Modes addresses these real‑world pain points with integrated dual‑pump hardware (water pump plus independent air pump), self‑cleaning capability and gun‑mounted Bluetooth remote control.

Built for professional end‑users, this unit delivers three distinct working modes via simple one‑touch switching. It works for agricultural plant protection, orchard care, greenhouse work, vehicle cleaning and large‑area public‑health sanitation. All specifications match real‑world field requirements without overstated performance, and the unit holds CE & EMC certification for global market access.

Three Practical Working Modes 

*Foam Cleaning Mode: Activate both water pump and air pump while adding cleaning agent. Generates dense foam for vehicle washing and surface deep‑cleaning.

*Fine Fog / Mist Mode: Run both pumps without detergent. Liquid converts into ultra‑fine fog, suitable for disinfection, pest extermination, dust suppression and epidemic prevention.

*Standard Spraying Mode: Switch on water pump only. Operates as a regular backpack sprayer for plant watering and general‑purpose surface cleaning.

Stand‑Out Core Advantages

Gun‑Mounted Bluetooth Remote Control

Bluetooth remote controller is fixed on the high‑pressure spray gun and communicates exclusively with the sprayer main host. Smartphone pairing is NOT supported. Six‑gear flow adjustment lets operators change output directly at the spray gun, no need to walk back to the backpack unit during continuous field work.

18V DeWalt Slide‑Pack Battery Compatibility

Designed to reuse existing 18V DeWalt tool batteries from drills and power saws. No proprietary battery or extra charger required. A 5.2Ah battery offers up to 5‑hour continuous spray runtime. Built‑in over‑discharge protection safeguards both battery and pump hardware. Spare batteries can be rotated for all‑day non‑stop operation.

Constant‑Pressure Output Technology

Intelligent electronic control maintains stable working pressure even as battery power depletes. It ensures consistent droplet size and uniform atomisation from full tank until liquid runs out, avoiding uneven spray coverage caused by voltage drop.

Heavy‑Duty 16L Chemical‑Resistant Tank

Constructed from modified polypropylene material. The 16‑litre knapsack tank balances comfortable carrying weight and large liquid volume. It resists damage from fertilisers, pesticides, disinfectants and cleaning detergents, and withstands impact in rough outdoor conditions.

Dual‑Pump Hardware & Reliable Service Life

Combines industrial‑grade diaphragm water pump and dedicated air pump. Pump service life reaches 1000 working hours; battery cycle life ≥1000 cycles.

Why Partner With Crosstec

Starting lithium sprayer R&D back in 2017 when most competitors still relied on lead‑acid power systems, Crosstec accumulates deep practical knowledge of real‑world equipment failure points and end‑user requirements.

We supply distributors and OEM partners across more than 50 countries. Our sprayers are deployed in French vineyards, Brazilian citrus orchards, Southeast Asian vegetable farms and Middle‑East sanitation projects. We understand variable local water quality, diverse agrochemical formulas and regional operating habits.

Our patented constant‑pressure system keeps pressure stable as battery drains, solving a common weakness found on many generic sprayers. Every single unit receives full functional factory inspection (not random sampling), lowering DOA return risks for our distribution partners. We support custom logo, packaging and parameter tuning for OEM / private‑label projects.Real‑World 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 from ordinary backpack sprayers?

A1: This upgraded unit adopts dual‑pump setup (water pump + air pump), delivering foam cleaning, fine fog disinfection and conventional spraying. It is fitted with a Bluetooth remote mounted on spray gun; remote only connects with sprayer main host, mobile phone connection is unavailable. Six‑gear flow adjustment enables convenient on‑site setting changes.

Q2: Can I use my existing DeWalt batteries on this sprayer?

A2: Yes, compatible with standard 18V DeWalt slide‑pack batteries. 5.2Ah battery is recommended for maximum runtime of approximately 5 hours. Send us battery photos if you need pre‑order compatibility confirmation.

Q3: How can I adjust spraying flow rate?

A3: Operators utilise the 6‑gear Bluetooth remote controller installed on the high‑pressure gun. Flow ranges 0.9‑3.6 L/min, covering fine mist for young seedlings up to high‑volume output for large‑scale orchard jobs. Frequent nozzle replacement is unnecessary.

Q4: What liquids can be safely used inside the 16L tank?

A4: Compatible with fertilisers, herbicides, pesticides, disinfectants, detergents and other common agricultural and commercial cleaning solutions. It supports detergent mixing for foam generation and plain chemical liquid for fogging or regular spraying.

Q5: What is the maximum spraying distance?

A5: Maximum spraying distance exceeds 8 metres under correct nozzle configuration and proper operating conditions.

Q6: Do you support wholesale and OEM private‑label services?

A6: Yes. We have completed OEM and private‑label projects for distributors in over 50 countries. Custom branding, packaging and specification adjustments are available according to your local‑market requirements.

Q7: How does the gun‑mounted Bluetooth remote function work?

A7: The Bluetooth remote hardware is attached to spray gun, establishing wireless communication only with sprayer main unit. It provides six adjustable flow gears for on‑the‑spot output tuning. This Bluetooth module cannot pair with mobile phones and does not show battery level data.
