Safety cannot be left to chance, nor should it be entrusted to luck. The Dawang 8.5-meter industrial ceiling fan features a systematic safety design that extends from the blades and motor to the connection points and even the mounting to the ceiling beam—every component is engineered with safety in mind.
Real-time monitoring, proactive maintenance
The Dawang Intelligent Remote Control System provides real-time monitoring of equipment operating parameters, motor temperature rise, and equipment levelness.
Wire Rope Balance Protection
Four steel wire ropes, leveraging the principle of equilibrium and securely anchored to the building, ensure that the entire fan unit remains stable and does not sway or fall under external forces or airflow.
Vibration-damping and cushioning device
The leaf stem is crafted from 6061-T6 aerospace-grade aluminum alloy, fully encased in PU polyurethane and seamlessly integrated with the blade’s cushioning chamber, efficiently dissipating vibrations and stresses generated by blade rotation and eliminating resonance.
Safety ring
Integrate the five leaf stems with the motor’s top cover to ensure they remain securely attached and do not detach or fall.
High-strength riveting of blades
Each blade is riveted to the buffer cavity—upper and lower sections—using 16 high-strength rivets, creating an independently load-bearing surface; each rivet is designed to withstand a shear force of 1.5 tons.
One-piece petiole connection
It forms a robust, rigid monolithic structure, completely eliminating the joint gaps inherent in conventional split‑type designs and effectively resisting high‑frequency vibrations and inertial impacts.
Wire rope winding protection
The mounting plate is secured to the ceiling beam with a steel wire rope rated for a 1,000 kg tensile strength, ensuring that the fan’s overall structure remains stable and does not loosen or fall.
Abnormality Alarm System
The variable-frequency control system is equipped with built-in protection against overvoltage, overload, phase loss, and other faults; in the event of an abnormality, it automatically triggers an alarm and shuts down the fan.
e high-tensile-strength petiole material
6061-T6 leaf stalk, high strength and hardness, with a Rockwell hardness exceeding HB90, excellent corrosion resistance, and a tensile strength of up to 205 MPa.
Fall protection connector
The “concave” cross-section of the flange and the “convex” cross-section of the fall‑prevention connector interlock under gravity, ensuring a reliable connection between the motor flange and the motor.
Streamlined Variable-Section Blade Design
Applying aerodynamic principles and chord‑length theory, and incorporating the relative linear velocity principle, the blade tapers and thins gradually from root to tip, achieving more balanced loading, more uniform airflow, and eliminating any central void.
Aviation-grade impact-resistant blade material
5052 aerospace-grade aluminum sheet can withstand tensile forces exceeding 3 tons, boasting exceptionally high material toughness. This ensures that, upon impact, the blade deforms rapidly to effectively absorb external forces, preventing blade fracture while minimizing damage to the motor and other structural components.
The Dawang Ventilation 8.5-meter industrial fan doesn’t just offer safety accessories—it delivers a safe, reliable core.
