  • 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

We deployed the AOISUN BWG-40 on our DJI FlyCart 100 for high-rise fire drills, and it’s a lifesaver for urban firefighting. The quick-release mount made installation fast—we had it ready in 10 minutes, no extra tools needed. The single/dual launch modes work perfectly for different window thicknesses, and the laser aiming let us precisely target locked windows from 12m away, breaking them cleanly on the first try. The 90m hose and 40mm diameter give us great coverage, and we could adjust the jet angle manually to target hotspots effectively. It handled 2.5Mpa pressure without issues, and the -20°C to 45°C temp range means it works in our city’s extreme weather. At only 1.95kg, it’s lightweight and doesn’t affect flight time. This is the most versatile aerial fire suppression tool we’ve used—highly recommended!

This AOISUN MYUAV fire bucket is a game-changer for UAV firefighting! Its IP68 waterproof and 800°C high-temperature resistance make it reliable in extreme conditions, while the multi-layer safety protection ensures uninterrupted mission execution. The easy installation and one-key control via the remote controller save a lot of time, and the compatibility with DJI FlyCart 30 and other heavy-load UAVs is a huge plus. The valve response time of ≤0.6s is impressive, allowing precise fire extinguishing. Highly recommended for forest fire and high-rise building fire suppression!
