Product Description
Wall Mounted Exhaust Fan
Product Introduction
Our innovative Industrial Solution Wall Mounted Fan for Greenhouse Air Management is equipped with a state-of-the-art air blower blade. Crafted from a patented design, this wing-type hollow blade, made from superior aluminum alloy, ensures not only a massive airflow but also exceptional efficiency. Revel in its low noise operation and reliable, steady performance that is guaranteed to enhance your greenhouse environment with advanced production craftsmanship.
Constructed from high-quality aluminum alloy, our exhaust fans undergo meticulous surface treatments, including anode oxidation, baked paint, and static plastic spraying. This ensures a durable and aesthetically pleasing finish that stands the test of time.
The fan angle is ingeniously adjustable within a range of 0°~90°, offering unparalleled flexibility in air direction and management.
Additionally, the fan can be seamlessly coupled with an adjustable valve or a filter net, empowering you with customizable airflow solutions to suit your specific needs.
Key Features
Core Advantages: Engineered for the Harshest Climates
1. Durable Materials for Longevity
- Structure: This remarkable fan is crafted with either 304 stainless steel or Q235 carbon steel frames, each meticulously finished with either hot-dip galvanization or a durable powder coating. Its robust construction is designed to withstand the harshest of environments, fending off high humidity, corrosive acidic gases such as ammonia often found in livestock barns, and intrusive dust. The end result is an impressive extension of service life by over 50%.
- Protection Rating: With an IP55 rating, this fan is expertly designed to be both dustproof and waterproof, making it the perfect candidate for long-term operations in outdoor or moisture-laden environments, all while requiring minimal maintenance.
2. Powerful Ventilation & Temperature Control
- High Airflow Design: Outfitted with advanced low-speed, high-torque pure copper motors and a range of impellers scaling from 300mm to a substantial 1200mm in diameter. It delivers an awe-inspiring airflow of up to 15,000 m³/h. This power facilitates the swift expulsion of hot, humid air, unwelcome odors, and hazardous gases, thereby drastically reducing temperature and humidity within greenhouses and livestock facilities. This ultimately results in minimizing mold proliferation and alleviating animal stress.
- Quiet Operation: The fan's aerodynamically refined impellers are designed to maintain whisper-quiet noise levels of ≤75dB, ensuring that there is no disturbance to livestock or interference with the growth of crops.
3. Flexible Installation & Adaptability
- Compact Square Design: Ingeniously designed to mount flush against walls, this fan is a perfect fit for greenhouse side walls, livestock barn walls, or even ceilings using optional ceiling brackets. It saves valuable space while offering robust performance.
- Adjustable Airflow Angle: With a manual 0-45° blade angle adjustment, airflow can be precisely directed to targeted areas, such as bottom ventilation for nurturing seedbeds or providing cooling in active livestock areas.
4. Intelligent Control & Energy Efficiency
- Multi-Speed Settings: Featuring a versatile 3-speed control (high/medium/low), this fan can be fine-tuned to suit seasonal variations and environmental demands, promoting energy conservation.
- System Compatibility: Seamlessly connects with temperature and humidity sensors or PLC control systems, allowing for automatic start/stop and speed adjustments. This integration empowers smart environmental management, making it a future-ready choice for modern facilities.
