Key Features
Core Advantages: Crafted to Withstand Challenging Environments
1. Robust and Long-lasting Materials
- Structure: Expertly constructed with resilient 304 stainless steel or durable Q235 carbon steel frames, with surfaces meticulously treated using hot-dip galvanization or advanced powder coating techniques. This ensures exceptional resistance to high humidity, corrosive gases (such as ammonia found in livestock barns), and dust, ultimately extending the product's service life by an impressive 50% and beyond.
- Protection Rating: Boasting an IP55 rating for dustproof and waterproof capabilities, this fan is engineered for sustained performance in outdoor or moisture-rich environments, requiring minimal maintenance over time.
2. Enhanced Ventilation & Precision Temperature Management
- Innovative High Airflow Design: Featuring low-speed, high-torque pure copper motors and a wide range of impeller sizes from 300mm to 1200mm in diameter, this fan delivers a substantial air volume of up to 15,000 m³/h. It proficiently expels hot, humid air, unpleasant odors, and detrimental gases, thereby effectively lowering temperature and humidity levels in greenhouses and livestock facilities, which significantly curtails mold growth and alleviates animal stress.
- Seamless Quiet Operation: With aerodynamically refined impellers, noise levels are meticulously maintained at ≤75dB, ensuring a serene environment that is free from disturbances to livestock or crop growth.
3. Versatile Installation & Adaptability
- Ingenious Compact Square Design: Designed to mount seamlessly against walls, this fan conserves space and is perfectly adaptable for installation on greenhouse side walls, livestock barn walls, or even ceilings when equipped with optional ceiling brackets.
- Customizable Airflow Angle: Featuring a manual blade angle adjustment range of 0-45°, this fan directs airflow with pinpoint precision, making it ideal for specific ventilation requirements, such as targeted bottom ventilation for seedbeds or cooling in high-activity livestock areas.
4. Smart Control & Energy-saving Efficiency
- Versatile Multi-Speed Settings: With a 3-speed control (high/medium/low), this fan adeptly adapts to varying seasonal and environmental demands, significantly reducing energy usage.
- Integrated System Compatibility: Seamlessly connects with temperature and humidity sensors or PLC control systems, facilitating automatic start/stop functions and speed adjustments to optimize smart environmental management.
