Compact Foldable Design for Easy Transport
The EV422 features a smart folding structure with a side-folding arm mechanism, reducing the folded dimensions to just 650×650×600 mm, ideal for easy storage and transport. When deployed, the drone expands to a 1000×1000×600 mm frame with a 1400 mm diagonal wheelbase, offering a stable aerial spraying platform.
High-Capacity Tank and Efficient Spraying System
Equipped with a 22-liter medicine cabinet, the EV422 is capable of delivering 1.5–4 L/min through a precision pressure nozzle system, covering an effective spray width of 3–5 meters. This design ensures uniform droplet distribution and maximized chemical utilization for crop protection.

Stable Performance with Smart Power System
Powered by a 58.8V (14S) battery with 20,000 mAh capacity, the drone achieves flight times of 20–25 minutes empty and 7–10 minutes fully loaded. The 3 m/s flight speed supports both small and medium field operations, enhancing coverage while maintaining spraying accuracy.
Intelligent & Durable Operating Features
The EV422 integrates GPS positioning, radar obstacle avoidance, remote control, and auto operation modes, making it suitable for both beginner and advanced users. Operating temperatures range from –10°C to 40°C, and its structure is waterproof and dustproof, ideal for various weather and terrain conditions.
