Key Features & Capabilities
  • Optimized Capacity Design: 40L standard capacity with lightweight construction (6.3kg empty) balances storage capacity and UAV load compatibility
  • Precision Control System: PWM valve control with 5V working voltage enables sensitive operation and adjustable spraying intensity
  • Rapid Deployment: 4-5 second full-volume spraying time ensures quick and even water distribution over fire sources
  • User-Friendly Operation: Top water filling for convenient refilling; hoisting installation for stable fixation under UAVs
  • Customizable Solutions: Supports 10-100L capacity customization to match different UAVs and fire scene requirements
  • Durable Construction: Sealed structure prevents water leakage; corrosion-resistant material adapts to harsh outdoor environments
  • Broad Compatibility: Suitable for most medium-sized fire-fighting UAVs, integrating seamlessly into existing fire-fighting systems
Applications
  • Urban Green Space Protection: Rapid water spraying on park, green belt, and square fires to suppress small fires before they spread
  • Agricultural Fire Suppression: Effective for farmland, orchard, and pastoral fires, delivering rapid water coverage to reduce agricultural losses
  • High-Rise Building Safety: Spraying water on external walls, windowsills, and eaves of high-rises to cool fire areas and prevent vertical spread
  • Industrial Site Protection: Suppression of initial small fires in factories, warehouses, and oil depots to prevent fire expansion
  • Forest Fire Containment: Deployment at forest edges to form water barriers, preventing small fires from spreading to large forest areas
  • Emergency Disaster Response: Water spraying for dust suppression, temporary cooling, or small-scale fire control after earthquakes and floods

The AOISUN MLV3D has transformed our airport security operations. This all-in-one payload combines 300m voice broadcast, 150m night searchlight, and dual-color warning lights perfectly for our patrols. The 120dB sound cuts through runway noise easily, and the TTS function lets us quickly broadcast evacuation alerts in both male and female voices. The stabilized 2800Lm searchlight tracks our camera angle flawlessly, illuminating runways at night with 0-100% brightness adjustment. The 1000m visible warning lights keep our drone visible to aircraft, even in low light. At just 266g, it’s lightweight enough for our DJI drone, and the Pilot2 integration makes control seamless. It’s operated reliably in -10°C winter mornings and 50°C summer afternoons—truly an all-weather workhorse for airport safety!
