Dawang fans Advantage:
1.Blade shape- Streamlined variable cross-section
Blade gradually narrows from root to tip and thins to tail then widens
like plane wing, more conform to the equal string length theory of aerodynamic
Fan volume is more even, higher and there is no hole in the middle, low air resistance, save energy consumption.
2.Blade weight-light
Each blade is 7.7KG,total weight for 5pcs is 38.5KG.Small blades ,light weight, reduce the motor load, increase the fan life.Low energy consumption.
3.blade petiole joint -- full mortise and tenon joint
The "convex" shape petiole and "concave" shape buffer device are locked with bolts, each blade is riveted together with damping device by 16 rivets. Blade, damping device and petiole become a whole, torsional and shear force reduced.
4.blade angleâ??3 degree up
Variable section design, tip 3 degrees higher than root, improving the air flow from cylindrical to conical, increase coverage, more than 1500 square meters.
5.petiole and wheel hub joint
Lock petiole in the pistion on the hub through the concave and convex surface.Petiole and chassis hub form an integral whole to prevent blade from upwarp, falling and waggling
It can load more than 8 tons tensile force
