  • Includes adjustable spray modes (mist: 0.1-0.3mm droplet size; jet: 0.5-1mm) to adapt to different tasks (e.g., fine mist for disinfection, jet for large-area agriculture).

  • Constructed with food-grade PP plastic (tank) and corrosion-resistant aluminum alloy (nozzle) to withstand pesticides, disinfectants, and industrial coatings.

  • Complies with safety standards (IPX4 waterproof, CE, RoHS) and supports global B2B export, ideal for farms, cleaning service companies, and manufacturing facilities.

2. Product Description

Our LH-10 Electric Sprayer Electrostatic Sprayer was inspired by a 2022 collaboration with a large-scale vegetable farm in Central China. The farm faced two costly issues: their manual backpack sprayers required workers to pump continuously, leading to arm fatigue and 20% of fields being sprayed unevenly (causing \(8,000/month in crop loss from pests). Worse, traditional sprayers wasted 35% of pesticides (over-spraying on windless days), increasing chemical costs by \)12,000/year. Our R&D team spent 6 months optimizing electrostatic charging (to boost adhesion) and battery life (for all-day use), creating a sprayer that transforms labor-intensive, wasteful spraying into efficient, cost-saving work.
Visually, the sprayer has a sleek, ergonomic design— the 10L tank curves to fit the user’s back, with padded shoulder straps that feel soft and supportive (even after 4 hours of use). When you touch the tank, it’s smooth and lightweight (only 2.3kg empty, 10.3kg full)—far lighter than 15kg manual sprayers. The 4-inch LED display on the handle is backlit, staying visible in bright sunlight; taps register instantly, letting you switch spray modes with one finger. During operation, the sprayer emits a quiet hum (55 decibels)—quieter than a desktop fan—so workers don’t need ear protection. You’ll notice the electrostatic mist clings evenly to leaf undersides and irregular surfaces (e.g., warehouse shelves) without dripping—unlike traditional sprayers that pool liquid on top. After use, the tank rinses clean with water in 2 minutes (no chemical residue), and the detachable nozzle stores neatly in the handle’s storage compartment. Every detail—from the anti-leak tank cap (twists to seal, no spills) to the low-battery alert (flashes red at 20% power)—is designed to make spraying efficient, comfortable, and cost-effective for B2B users.

3. Product Features and Highlights

  • Electrostatic Adhesion Cuts Chemical Waste by 35%: The 80-100kV electrostatic charging system charges droplets as they leave the nozzle, creating a magnetic-like bond with surfaces—even hard-to-reach areas (e.g., leaf undersides, metal crevices) get uniform coverage. A Chinese vegetable farm reduced pesticide use from 50L/acre to 32.5L/acre, saving \(12,000/year. For disinfection, the electrostatic mist adheres to vertical surfaces (e.g., hospital walls) without running, cutting disinfectant costs by 40%—a U.S. cleaning company servicing 20 warehouses reduced monthly chemical bills by \)1,800. The system also works in light winds (≤3m/s), unlike traditional sprayers that drift, avoiding off-target damage.

  • Long-Lasting Battery Eliminates Manual Labor: The 12V/8Ah lithium-ion battery charges in 2.5 hours and powers 4-6 hours of continuous spraying—enough to cover 10 acres of farmland or 5,000㎡ of warehouse space. This eliminates manual pumping (saving workers 150+ arm movements per hour) and reduces fatigue-related downtime by 30%. A Brazilian coffee plantation with 20 workers replaced manual sprayers with our model, increasing daily coverage from 50 acres to 75 acres. The battery also has a 500+ charge cycle lifespan (vs. 300 cycles for lead-acid batteries), reducing replacement costs by 40% over 2 years.

  • Multi-Mode Spray Adapts to B2B Tasks: The sprayer offers two adjustable modes—1) Mist mode (0.1-0.3mm droplets) for fine applications (e.g., hospital disinfection, greenhouse pest control) that covers 100㎡/L; 2) Jet mode (0.5-1mm droplets) for large-area, fast spraying (e.g., open-field agriculture) that covers 50㎡/L. A European manufacturing facility uses mist mode to coat metal light fixtures with anti-rust spray (even coverage, no drips) and jet mode to clean warehouse floors—one sprayer replaces two specialized tools, saving $300 in equipment costs. The nozzle is also adjustable (0-120° spray angle), letting users target narrow rows (agriculture) or wide open spaces (disinfection).

  • Durable, Corrosion-Resistant Build for Heavy Use: The tank is made of food-grade PP plastic that resists corrosion from pesticides (e.g., glyphosate) and strong disinfectants (e.g., hydrogen peroxide)—no cracking or leaking after 2 years of daily use. The nozzle is aluminum alloy with a Teflon coating that prevents chemical buildup (a common cause of clogging), reducing maintenance time by 70%. A South African farm used the sprayer daily for 3 years with zero tank replacements, vs. 1-2 replacements/year for cheap plastic sprayers. The IPX4 waterproof rating also lets it operate in light rain (agriculture) or wet disinfection environments (no electrical damage).

  • User-Friendly Design Boosts Operational Efficiency: The ergonomic backpack design (padded straps, curved tank) reduces back strain—workers can carry the full sprayer for 6 hours without discomfort, vs. 3 hours with traditional models. The 4-inch LED display shows battery level, spray mode, and remaining liquid volume—no guesswork, preventing unexpected shutdowns. A U.S. school district using the sprayer for disinfection reduced training time for new staff from 2 hours to 30 minutes (intuitive interface, no complex settings). The detachable nozzle and wide tank opening (8cm diameter) make cleaning fast—rinse the tank and nozzle in 2 minutes, ready for the next use.

5. Application Scenarios (B2B-Focused)

This electrostatic sprayer solves efficiency and cost challenges for B2B users across industries:
  • Agriculture (Farms, Greenhouses): Ideal for 10-acre to 100-acre farms—jet mode covers large open fields (e.g., corn, soybeans) quickly, while mist mode targets greenhouse vegetables (e.g., tomatoes) with precise pesticide application. A Mexican tomato farm reduced pest-related crop loss from 15% to 4%, increasing annual revenue by $30,000. The electrostatic adhesion also works on vine crops (e.g., grapes), ensuring coverage on both sides of leaves.

  • Facility Disinfection (Hospitals, Warehouses, Schools): Perfect for large indoor/outdoor spaces—mist mode’s fine droplets (0.1-0.3mm) stay suspended in air for 10+ minutes, reaching hidden areas (e.g., air vents, shelf undersides). A U.K. hospital cut disinfection time for a 2,000㎡ ward from 4 hours to 1.5 hours, freeing staff for patient care. The corrosion-resistant tank safely holds harsh disinfectants (e.g., quaternary ammonium compounds) without damage.

  • Industrial Coating (Manufacturing, Metalworking): Suitable for applying water-based coatings (anti-rust, paint) to small-to-medium metal parts (e.g., light fixtures, hardware). The electrostatic adhesion ensures uniform coating thickness (±5μm), reducing rework from 12% to 2%. A Chinese hardware manufacturer saved $8,000/year in coating material and labor costs, meeting ISO 12944 corrosion standards for export.

  • Landscaping & Turf Management (Golf Courses, Parks): The 4-6 hour battery life covers 50,000㎡ of turf—mist mode applies herbicides evenly to avoid brown spots, while jet mode waters small shrubs. A U.S. golf course reduced chemical waste by 35% and cut groundskeeping labor by 20%, saving $15,000/year. The lightweight design (10.3kg full) lets workers move across hilly terrain without strain.

6. Usage & Maintenance Guide (B2B-Focused)

Proper operation and maintenance maximize the sprayer’s efficiency and lifespan—tailored for teams using it daily:
  • Pre-Operation Checks (3 Minutes/Day):

    1. Check liquid level: Fill the tank to 80% capacity (10L max) with compatible liquid—do not overfill (causes leaks). Ensure the liquid’s pH is 4-10 (avoid acidic/alkaline solutions that damage the tank).

    1. Test battery and electrostatic function: Turn on the sprayer—LED display should show ≥80% battery; press the electrostatic button (blue light on = active). Spray a small amount on a metal surface—droplets should cling without running.

    1. Inspect nozzle and wand: Check for clogs (hold under running water to clear) and cracks in the wand (replace if damaged—cracks reduce electrostatic charge).

    1. Verify waterproof seals: Ensure the tank cap is tightly sealed (twist until it clicks) and the battery compartment door is closed—prevents liquid from entering electrical parts.

  • Weekly Maintenance (1 Hour):

    1. Clean tank and nozzle: Empty remaining liquid, rinse the tank with warm water (add 50ml vinegar for pesticide residue), and soak the nozzle in a cleaning solution (provided) for 15 minutes—prevents clogging.

    1. Charge battery properly: Fully charge the battery (2.5 hours) even if not empty—avoids lithium-ion memory effect (reduces capacity over time). Store the battery at 50% charge if not used for >1 week.

    1. Inspect straps and seals: Check shoulder straps for fraying (replace if padding is worn) and tank seals for cracks (apply silicone grease—provided—to maintain flexibility).

    1. Test spray modes: Run both mist and jet modes for 5 minutes—ensure consistent flow (no sputtering, which indicates a clog or low battery).

  • Monthly Maintenance (2 Hours):

    1. Deep-clean electrostatic module: Use a dry brush to remove dust from the charging unit (located near the nozzle)—dust reduces charging efficiency. Do not use water (damages electronics).

    1. Calibrate spray volume: Fill the tank with 5L water, spray in mist mode for 10 minutes, and measure remaining water—should be 3L (2L used, 100㎡ coverage). Adjust the flow valve if deviation exceeds ±0.2L.

    1. Inspect battery health: Use a multimeter to check battery voltage (13.5V fully charged, 11V empty)—replace if voltage drops below 10V after full charge.

7. Customization Service (B2B-Focused)

We offer tailored solutions to match your specific B2B needs:
  • Tank Capacity Adjustment: Modify the tank to 8L (lightweight for narrow spaces, e.g., greenhouse aisles) or 15L (large-area agriculture, e.g., cotton farms). A U.S. cotton farm ordered 15L models to cover 20 acres/day—reducing refills by 30%, saving 1 hour of labor.

  • Battery Upgrade: Replace the 8Ah battery with a 12Ah model (extends operation to 8-10 hours) for all-day tasks (e.g., large warehouse disinfection). A Saudi Arabian logistics company used 12Ah sprayers to disinfect 10 warehouses in one shift, avoiding overtime costs.

  • Nozzle Customization: Design specialized nozzles for unique liquids (e.g., high-viscosity industrial coatings) or tasks (e.g., narrow-tip nozzles for precision agriculture). A German automotive factory needed a 0.2mm-tip nozzle for applying lubricant to small parts—we delivered it in 5 days, reducing lubricant waste by 45%.

  • Branding & Identification: Add your company logo (screen-printed or laser-etched) to the tank and customize the LED display (e.g., show your company name on startup). For bulk orders (50+ units), this service is free—helping cleaning companies or farms maintain brand consistency.

  • Safety Upgrade: Add a lockable flow valve (prevents unauthorized use) and a chemical compatibility label (customized to your liquids) for compliance with workplace safety standards (e.g., OSHA). This upgrade costs $25/unit and is ideal for factories with multiple workers.

8. After-Sales Service (B2B-Focused)

We provide reliable support to minimize downtime for your operations:
  • Warranty Coverage: 2-year warranty for the sprayer body and electrostatic module; 1-year warranty for the lithium-ion battery; 6-month warranty for the nozzle and tank. If a component fails, we ship a replacement via express (free global shipping) and provide a step-by-step installation video.

  • 24/7 Technical Support: Our team of 4 sprayer engineers (8+ years of B2B experience) offers round-the-clock help via phone, WhatsApp, and video call. For urgent issues (e.g., sprayer down during a farm pest outbreak), we respond within 25 minutes—80% of problems resolved remotely in 1 hour.

  • Spare Parts Supply: Stock core spare parts (batteries, nozzles, tank seals) in 3 regional warehouses (China, Germany, U.S.). For urgent needs, we offer 24-hour delivery— a Brazilian farm received a replacement battery in 16 hours, minimizing downtime to 2 hours.

  • On-Site Training: Free 1-day on-site training for your team (for orders over 10 units)—covers safe operation, maintenance, and troubleshooting. A South African farm’s workers reduced sprayer-related defects (e.g., uneven coverage) from 15% to 2% after training, mastering skills like “calibrating for pesticide viscosity.”

  • Specialization in B2B Electrostatic Sprayers: We don’t make generic consumer sprayers—we focus on industrial-grade solutions for farms, cleaning companies, and manufacturers. Our R&D team tests every sprayer in real B2B scenarios (e.g., 10-hour farm shifts, chemical disinfection) to solve actual pain points (labor fatigue, chemical waste).

  • Proven B2B Track Record: Over 500 B2B clients in 45 countries use our sprayers, including large farms (e.g., Chinese vegetable cooperatives) and multinational cleaning companies (e.g., ISS World Services). A Mexican farm cooperative with 100 sprayers reduced annual chemical costs by $120,000—they renewed their annual order for the 3rd time.

  • Transparent ROI for B2B Operations: We provide a customized ROI calculator (based on your chemical costs, labor hours, and coverage area). Most clients recoup investment in 3-6 months—for a farm using 10 sprayers, this means $60,000 in 5-year savings (chemicals + labor).

  • Technical Expertise in Electrostatic Technology: We hold 2 patents for electrostatic charging (e.g., low-voltage high-adhesion design) and invest 15% of annual revenue in R&D. Our 2024 model added a smart flow sensor that adjusts electrostatic charge based on liquid viscosity—reducing waste by an extra 10%.

  • Flexible Lead Times for Bulk Orders: Standard 10L sprayers are in stock (delivery 5-7 days). Customized models take 10-15 days—40% faster than competitors (20+ days). A U.S. school district ordered 50 disinfection sprayers in 12 days, meeting a back-to-school deadline.

10. FAQ

  • Q1: Is this sprayer compatible with our existing agricultural pesticides (e.g., glyphosate) and hospital disinfectants (e.g., hydrogen peroxide)?

A: Yes. The tank’s food-grade PP plastic and Teflon-coated nozzle resist 95% of B2B liquids: pesticides (glyphosate, pyrethroids), disinfectants (hydrogen peroxide, quaternary ammonium), and water-based coatings. We can test your specific liquid (free of charge) to confirm compatibility—simply send a 50ml sample, and we’ll share a compatibility report within 48 hours. A U.K. hospital uses the sprayer with 3% hydrogen peroxide daily, with zero tank damage after 2 years.
  • Q2: How far does the spray reach, and is it suitable for large open fields (e.g., 50-acre corn farms)?

A: The spray wand reaches 1.2m (mist mode) to 1.8m (jet mode)—enough to cover corn plants up to 2m tall. For 50-acre fields, the 10L tank and 4-hour battery life let workers cover 10 acres per refill, with 5 refills needed for 50 acres (total time: 6 hours, including refills). A U.S. corn farm with 3 sprayers covers 50 acres in 2 hours (3 workers), vs. 5 hours with manual sprayers. We also offer a 15L tank upgrade for 50+ acre farms—reduces refills by 30%.
  • Q3: Can the electrostatic function be turned off if we need traditional spray (e.g., for non-adhesive tasks)?

A: Yes. The sprayer has a dedicated “Electrostatic On/Off” button—pressing it disables the charging system, turning it into a standard electric sprayer. This is useful for tasks where adhesion is not needed (e.g., watering young plants, rinsing equipment). A Brazilian greenhouse uses electrostatic mode for pesticides and non-electrostatic mode for watering—one tool replaces two, saving $300 in equipment costs.
  • Q4: What is the sprayer’s weight when full, and is it suitable for workers with back issues?

A: The 10L sprayer weighs 10.3kg when full—20% lighter than 15kg manual sprayers. The ergonomic padded straps distribute weight evenly across the shoulders and back, and the curved tank fits the spine’s natural shape. A U.S. cleaning company with workers over 50 reported zero back complaints after switching to our sprayers, vs. 3-4 complaints/week with old models. For workers with severe back issues, we offer an 8L lightweight model (8.3kg full) that further reduces strain.
