Bolivia Commercial ceiling fan

Variable-frequency speed control	High efficiency and energy saving	Three-dimensional natural style	Intelligent Control	Interior anti-fall wire rope	Low noise

The HDS series of permanent-magnet, variable-frequency commercial ceiling fans from Huada is a product specifically developed to enhance environmental comfort. It features a self-designed, variable-frequency, high-efficiency, energy-saving permanent-magnet external-rotor synchronous motor. These fans offer numerous advantages, including low noise, compact size, light weight, a streamlined structure, and an aesthetically pleasing appearance.

Permanent-magnet variable-frequency commercial ceiling fan

Widely used in large‑space venues such as shopping malls, restaurants, fitness centers, industrial plants, logistics warehouses, waiting areas, exhibition halls, and sports arenas, this innovative energy‑saving fan provides spatial ventilation and helps cool occupants. It delivers a powerful airflow that creates dynamic air movement within the space, promoting comprehensive air circulation. Resembling nature’s gentle breeze, it offers a refreshingly natural cooling experience.

Natural three-dimensional airflow enhances human comfort.

2.4~3.7m Leaf blade diameter	1 m/s to 4.5 m/s Wind speed is infinitely adjustable.	330m² Maximum effective coverage area

The HDS series of permanent‑magnet, variable‑frequency commercial ceiling fans features a unique airfoil‑shaped blade design with diameters ranging from 2.4 to 3.7 meters. Crafted using aerodynamic principles and advanced manufacturing techniques, these airfoil blades generate a circulating airflow through powerful air‑mixing action, creating a gentle breeze that mimics nature. This delivers a three‑dimensional wind sensation from all directions, increasing the surface area for sweat evaporation and enhancing comfort. At the same time, it avoids the health issues often associated with traditional high‑speed fans operating continuously in a directed airflow, significantly improving environmental comfort. The HDS series allows users to adjust airflow volume according to specific application needs, with wind speeds freely adjustable between 1 m/s and 4.5 m/s. In open spaces, a single energy‑efficient commercial fan can effectively cover an area of up to 330 m².

Permanent Magnet Synchronous Motor

Features:

• The rotor has no copper losses.
• High efficiency, high precision
• High power factor
• Improve the power grid environment
• Frequency modulation bandwidth (0–200 Hz)
• Small size, lightweight
• Energy-saving and highly efficient (power-saving)

Airfoil-shaped fan blades + energy-saving tail fin

Fan blade:
It is manufactured using aluminum–magnesium alloy extrusion and stretch‑forming, with an airfoil‑shaped internal rib structure, offering high strength, excellent toughness, light weight, long service life, and safe operation. The fan blades undergo a T5+ bright‑finish anodizing treatment, enhancing their corrosion and oxidation resistance to withstand demanding operating environments.

Wing-type internally stiffened structure

Diameters of 2.4 meters and 3 meters are available with either curved or straight blades.   
Diameter 3.7 meters, with straight blades.

Tail:
Made from high-temperature‑resistant materials, the product boasts a more aesthetically pleasing design. As the fan blades rotate, vortices form at their trailing edges; the tail fin helps dissipate this energy loss, stabilizing the fan’s operation and ensuring airflow aligns more closely with aerodynamic principles.

Intelligent Control System

• Permanent-magnet synchronous variable-frequency technology, with electromagnetic interference protection, radiation shielding, compact size, lightweight design, and an elegant appearance.
• Wired SPI communication: power-on, shutdown, acceleration, deceleration, natural wind mode, forward/reverse switching, timed shutdown, and lighting (optional).
• Wireless remote control: power on/off, 4 speed settings, natural wind mode, forward/reverse rotation switch, and optional lighting.
• 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 abnormal conditions.
