Key Features
Core Advantages: Built for Tough Conditions
1. Durable Materials for Longevity
- Structure: Constructed with 304 stainless steel or Q235 carbon steel frames, surface-treated with hot-dip galvanization or powder coating to resist high humidity, acidic gases (e.g., ammonia in livestock barns), and dust, extending service life by over 50%.
- Protection Rating: IP55 dustproof and waterproof, designed for long-term operation in outdoor or wet environments with minimal maintenance.
2. Powerful Ventilation & Temperature Control
- High Airflow Design: Equipped with low-speed, high-torque pure copper motors and impellers ranging from 300mm to 1200mm in diameter, delivering up to 15,000 m³/h of air volume. Quickly expels hot, humid air, odours, and harmful gases to reduce temperature and humidity in greenhouses and livestock facilities, minimizing mould growth and animal stress.
- Quiet Operation: Aerodynamically optimized impellers ensure noise levels ≤75 db, avoiding disturbance to livestock or crop growth.
3. Flexible Installation & Adaptability
- Compact Square Design: Mounts flush against walls to save space, suitable for greenhouse side walls, livestock barn walls, or ceilings (with optional ceiling brackets).
- Adjustable Airflow Angle: The manual 0-45° blade angle adjustment directs airflow precisely, making it ideal for targeted ventilation, such as bottom ventilation for seedbeds or cooling for livestock activity areas.
4. Intelligent Control & Energy Efficiency
- Multi-Speed Settings: A 3-speed control (high, medium, and low) matches seasonal and environmental needs, reducing energy consumption.
- System Compatibility: Connects to temperature and humidity sensors or PLC control systems for automatic start/stop and speed adjustment, enabling innovative environmental management.
