Product Description

Introducing our versatile HVLS (High Volume Low Speed) industrial ceiling fans, available in 3m, 5m, and the impressive 7.3m sizes, designed specifically to meet all your warehouse ventilation demands.
Discover the FJDA series-our cutting-edge permanent magnet frequency conversion ceiling fans, meticulously crafted to enhance energy efficiency and foster a more comfortable working environment. Empowered by our proprietary permanent magnet motor, these fans boast compact dimensions, feather-light weight, and superior performance. Experience unparalleled energy savings, whisper-quiet operation, variable frequency control, and a sleek design that blends seamlessly into any space.

Our ceiling fans are a staple across a multitude of expansive environments such as industrial workshops, logistics hubs, waiting areas, exhibition centers, stadiums, and other towering spaces. They introduce an innovative solution for ventilation, simulating the gentle embrace of a natural breeze. By propelling a vast stream of air downward, these fans create a dynamic air layer at ground level, promoting comprehensive air circulation and ensuring an invigorating natural airflow experience.

Applications:
Large logistics warehouses and distribution centers can greatly benefit from improved air quality, effective dehumidification, and cooling capabilities. These fans also play a pivotal role in preventing rust and decay of stored goods, thereby enhancing the overall working environment.

In expansive workshops, ranging from mechanical processing and automobile repair to aircraft assembly and shipbuilding, our fans significantly boost ventilation efficiency, ensuring a more productive and comfortable workspace.

Public buildings, including bustling shopping malls, stadiums, railway stations, and airports, experience enhanced air circulation with our fans. They effectively dispel odors and promote a pleasant and comfortable public atmosphere.

On large farms, encompassing dairy farms, feedlots, and hatcheries, our fans are instrumental in maintaining superior air quality. By removing excess moisture, eliminating odors, and reducing disease risks, they help create a healthier and more productive environment for livestock.

Main Features

 

Introducing our innovatively engineered external rotor motor, meticulously crafted with our proprietary IMU configuration. This design seamlessly integrates an active control strategy for the ESC with a coordinated regenerative braking strategy, delivering substantial torque and synchronous permanent magnet efficiency. Experience unparalleled integration, reliability, and transmission efficiency.

Our system ensures comprehensive torque recovery and auxiliary braking within peak torque limits. Crafted with premium aluminum alloy components, our design achieves a lightweight structure without compromising on strength.

 

Smart Controller:
1 Featuring a fully enclosed design, our controller boasts an IP66 protection grade - making it dust-proof, waterproof, and moisture-proof. It withstands high-temperature conditions, making it ideal for both indoor and outdoor environments.
2 Enjoy a position-free vector control system that resists electromagnetic interference and radiation. Its compact, lightweight structure combines with a sleek, aesthetically pleasing design.

3 Simplified system functionality with just four intuitive buttons for operation: start, stop, speed up, and slow down.

4 Our system is fortified with protective features including overvoltage, undervoltage, voltage loss regulation, and more. It shields against current, phase loss, overload, collisions, overheating, lightning, and abnormal conditions.

5 Choose the customizable intelligent control mode tailored to your specific needs.

Fan Blade: Crafted from high-strength aluminum-magnesium alloy used in aviation, this component is extruded and stretched for maximum durability. The internally stiffened wing offers exceptional strength, impeccable toughness, and minimal weight, ensuring a long service life and safe usage. The fan blade's surface undergoes T5 plus bright oxidation treatment, enhancing its corrosion and oxidation resistance for specialized environmental operations.

Tail:
During fan operation, the motion of the air produces vortices at the
aerofoil fan blade's trailing edge. The tail wing is meticulously designed
to counteract this energy loss, stabilizing fan performance and ensuring
that airflow aligns with the aerodynamic principles more efficiently.
