Lesotho Wall-mounted fan

Applicable application scenarios  
Wall-mounted fans are custom-designed to address the challenges of complex environments where industrial ceiling fans cannot be installed. They are ideal for spaces where ceiling structure, load-bearing capacity, or overhead traffic constraints make the installation of conventional industrial ceiling fans impractical. In high‑ceiling areas such as industrial plants, logistics warehouses, waiting rooms, exhibition halls, sports arenas, and large shopping malls, they serve as a new type of fan for space ventilation and personnel cooling.

Flexible suspension system  
It can be installed in a variety of settings, including steel‑frame columns and concrete walls. The entire unit is fabricated from high‑strength hot‑rolled steel, seamlessly welded, treated with a conversion coating process, and finished with high‑pressure electrostatic powder coating, offering corrosion resistance, vibration resistance, and fall protection, ensuring years of reliable, maintenance‑free operation.

Left-right head-shaking function  
The fan features an independent automatic on/off switch and a oscillation function, allowing it to swing left and right up to 45° for wide-angle airflow that covers the largest possible area.

The HDB series of permanent‑magnet, variable‑frequency wall‑mounted fans from Huada is a new generation of industrial fans designed specifically for spaces with limited ventilation, such as factory workshops. Featuring a self‑developed, variable‑frequency, high‑efficiency, energy‑saving permanent‑magnet synchronous motor, these fans offer advantages including low noise, compact size, light weight, and an aesthetically pleasing appearance. The fan incorporates a unique airfoil‑shaped blade design, with diameters ranging from 0.6 to 2 meters, and is manufactured using aerodynamic principles and advanced production techniques. Its powerful airflow creates a circulating air pattern that mimics nature’s gentle breeze, delivering multidirectional, three‑dimensional wind that enhances sweat evaporation and boosts comfort. At the same time, it eliminates the health issues often associated with traditional high‑speed fans operating continuously in a directed airflow, significantly improving environmental comfort. The HDB series wall‑mounted fans can be customized to meet the specific needs of different applications, with adjustable airflow rates spanning 1 to 8 m/s. In open spaces, a single energy‑efficient unit can deliver air up to 24 meters away.

Intelligent Control System

Supports smart mobile control (optional)

• Control System: Featuring a high‑protection rating that effectively withstands external contamination from oil, dust, and moisture, the WC control technology offers simple commissioning, independent control of the swivel button, and exceptional adaptability.
• The system employs sensorless sinusoidal vector control, offering electromagnetic interference protection, radiation shielding, a compact footprint, lightweight construction, and an elegant appearance.
• The system features simple, easy-to-understand functions, with responsive and crisp button operation.
• The system features built-in protection against overvoltage, undervoltage, and voltage loss, as well as safeguards for overcurrent, phase failure, overload, collision, overheating, lightning strikes, and other abnormalities.
• Supports expanded customizable smart control methods: WLAN, Bluetooth, 4G, time-based scheduling, PID control, temperature control, and centralized control.
