Product Description
Introducing the 3m, 5m, and 7.3m HVLS Type Industrial Ceiling Fan, expertly engineered for warehouses to ensure optimal air circulation and unmatched cooling efficiency.
Discover the avant-garde FJDA series, featuring cutting-edge permanent magnet frequency conversion ceiling fans. These fans are meticulously crafted to elevate energy efficiency and drastically reduce consumption, while enhancing the comfort of your working environment. Powered by an innovative self-designed permanent magnet motor, these fans boast numerous features: compact size, feather-light design, superior efficiency, significant energy savings, whisper-quiet operation, adaptive frequency control, sleek and stylish structure, and an aesthetically pleasing appearance.
Our ceiling fans are extensively utilized in industrial workshops, logistics storage areas, waiting rooms, exhibition halls, stadiums, and ultra-tall spaces. As pioneers in ceiling fan space ventilation, they excel at cooling personnel by propelling a substantial volume of air downwards, establishing a dynamic air layer movement across the ground. This facilitates comprehensive air circulation, mimicking the soothing essence of a natural breeze, allowing users to luxuriate in the refreshing embrace of nature-infused airflow.
Applications:
Large Logistics Warehouses and Distribution Centers: Elevate air quality, attain dehumidification, and achieve cooling while safeguarding against rust and decay. Enhance the working environment for improved operational conditions.
Super Large Workshops: Ideal for spaces like mechanical processing, automobile repair hubs, aircraft assembly lines, and shipbuilding facilities, these fans significantly boost ventilation efficiency.
Public Buildings: Perfect for bustling venues such as shopping malls, stadiums, railway stations, and airports. These fans ensure robust air circulation, eradicate unpleasant odors, and cultivate a serene and comfortable public setting.
Large Farms: From dairy farms to feedlots and hatcheries, our fans promote exemplary ventilation. They elevate air quality, efficiently extract moisture, eliminate odors, and play a crucial role in minimizing disease prevalence among livestock.

Main Features
Introducing an innovative marvel in motor technology, our self-developed external rotor motor features an integrated IMU configuration. This enables a cutting-edge ESC active control strategy, complemented by a coordinated regenerative braking strategy. With robust torque and permanent magnet synchronization, this motor achieves an exceptional level of integration, boosting both reliability and transmission efficiency.
Our system effortlessly accommodates any torque recovery or auxiliary braking within peak torque levels. By incorporating aluminum alloy materials in key components, we've accomplished a design that is wonderfully lightweight.
Smart Controller:
1 Designed with a fully enclosed structure, our system boasts an impressive IP66 protection grade. It shields against dust, water, moisture, and even high temperatures, making it ideal for demanding indoor and outdoor environments.
2 This no-position vector control system is built to resist electromagnetic interference and radiation. Its compact and lightweight form, combined with an attractive design, ensures optimal performance.
3 Operating the system is a breeze thanks to its intuitive functionality. With just four easy-to-use buttons-start, stop, speed up, and slow down-complexity is a thing of the past.
4 Equipped with comprehensive protective features, the system guards against overvoltage, undervoltage, voltage loss, and more. It also offers protection from current issues, phase loss, overload, collisions, overheating, lightning, and any abnormalities.
5 Enjoy the flexibility of a customizable intelligent control mode to suit specific preferences and needs.
Fan Blade: Crafted from high-strength aluminum-magnesium alloy, our fan blades are produced through an extrusion and stretching process used in aviation. Internally reinforced, these blades offer outstanding strength, superior toughness, and lightweight design, ensuring longevity and safe operation. Featuring T5+surface bright oxidation treatment, these blades are resistant to corrosion and oxidation, making them perfect for challenging environments.
Tail:
As the fan blades spin, vortexes are naturally generated at
the end of the aerofoil fan blade. The innovative tail wing is engineered to
eliminate this energy loss, thus stabilizing fan operation
and ensuring air flows that are more aligned with aerodynamic principles.
