In the factory, industrial fans deliver coolness,
But do you know that the hidden danger of falling fan blades,

is quietly threatening production?

The tensile strength defect of traditional bolted connections makes "fan blades flying out" an industry pain point.

Why are fan blades prone to "loss of control"?

In industrial environments, high-frequency operation and continuous vibration of fans, as well as environmental temperature differences causing thermal expansion and contraction, cause tearing and damage to traditional bolted connections, resulting in a decrease in tensile strength at the connection points, leading to a chain of failures such as thread slippage and fan blade loosening. Uncontrolled high-speed fan blades will seriously threaten the safety of personnel and equipment. Da Wang Ventilation HVLS Fan Safety Solution

1. Abandon traditional bolts

One-piece blade shank + built-in buffer cavity design

Achieve structural integration, coupled with a 16-point matrix riveting design, each rivet can withstand 1.5 tons of shear force, dispersing the load to reduce the risk of single-point overload failure.

2. Inner cone bushing + anti-fall plate

Patented inner cone bushing + anti-fall plate

Forms a structural interlock with the motor output shaft, using gravity for natural tightening to ensure reliable connection; the anti-fall plate is fitted with the chassis, intercepting extreme situations such as hub detachment and shaft breakage, building a dual-level anti-fall system.

3. Dual certification of technology and reputation

Multiple protective designs are patented

The product has passed international authoritative certifications such as FCC, CE, ROHS, and UL!
10 years of zero fall records.

“Safety” is not an add-on, but a bottom line!

Da Wang Ventilation uses "design + certification + reputation" triple guarantee to build a protective barrier for every industrial space!
