Key Features
Core Advantages: Built for Tough Conditions
1. Durable Materials for Longevity
- Structure: Meticulously crafted with robust 304 stainless steel or resilient Q235 carbon steel frames, these fans are surface-treated with advanced hot-dip galvanization or powder coating. This ensures exceptional resistance to high humidity, acidic gases such as ammonia common in livestock barns, and dust. The result is an impressive extension of service life by over 50%, making it a durable choice for demanding environments.
- Protection Rating: With an IP55 rating, these fans are engineered to be dustproof and waterproof, tailored for seamless, long-term operation in outdoor or wet conditions. Expect minimal maintenance efforts, even in challenging scenarios.
2. Powerful Ventilation & Temperature Control
- High Airflow Design: Featuring low-speed, high-torque pure copper motors and a versatile range of impellers from 300mm to 1200mm in diameter, these fans deliver a robust airflow of up to 15,000 m³/h. They swiftly expel hot, humid air, unpleasant odors, and hazardous gases, effectively lowering temperature and humidity in greenhouses or livestock facilities, thus mitigating mold growth and alleviating animal stress.
- Quiet Operation: Thanks to aerodynamically optimized impellers, these fans maintain noise levels at a gentle ≤75dB. This ensures a tranquil environment, undisturbed by noise, promoting optimal conditions for livestock and crop growth.
3. Flexible Installation & Adaptability
- Compact Square Design: Its sleek design allows for flush wall mounting, conserving valuable space. Perfectly suited for side walls in greenhouses, barn walls, or ceilings when using optional ceiling brackets, it provides versatile installation options to fit seamlessly into various settings.
- Adjustable Airflow Angle: The manual adjustment feature offers a 0-45° blade angle, enabling precise airflow direction. This is ideal for targeted ventilation needs, such as bottom ventilation for seedbeds or cooling focused on livestock activity zones.
4. Intelligent Control & Energy Efficiency
- Multi-Speed Settings: With a 3-speed control option, ranging from high to medium to low, these fans can be adjusted to match seasonal and environmental demands, ensuring substantial energy savings.
- System Compatibility: Seamlessly integrates with temperature and humidity sensors or PLC control systems, allowing for automatic start/stop functions and speed adjustments. This compatibility enhances smart environmental management, optimizing efficiency and convenience.
