Dawang fans introduction
The wind generated by Dawang industrial fans provided for this project is similar to the natural breeze system,It's the wind speed that your skin feels best when it's cool .The body can feel the temperature difference of 5-8 degrees, they can have a comfortable working environment in hot summer, improving production efficiency.
"Healthy-wind" series industrial large ceiling fans maximum diameter can reach 7.3m , hung on the rooftop. Similar to regular small ceiling fans, but different from small ceiling fans, they can generate large air flow at low speed , form cross-ventilation through the whole building, to realize ventilation and cooling
Dawang fans function
1. Ventilation Our Fans can promote the air circulation, perfect streamline make users enjoy the 2-4 m/s spatial formula air supply, form the nature breeze system, promoting dispersion of heavy dust, moisture, Co2 and poor air to improve the air quality, create a healthy, dry and safety work environment, enhance the work efficiency
2.Convenient Adopted the latest frequency conversion stepless speed control system, convenient to use. Humanized operation interface make users to enjoy the beauty of science and technology of life
3.Drying:Large air volume promote air flow effectively, make moisture well disperse and decrease the problems appear probability such as bedbug, mycete and so on
4.Elegant and durable:After complex surface treatment, the fan can avoid cleaning. The fan life can more than 10 years.
5.save energy and reduce consumption:The rated power of whole machine is 1.5kw, which can cover more than 1400m2 area, energy consumption is only 0.8 KWH. Compared with small powerful fans and high-power air conditioners, which reduces your costs greatly
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

Ceiling Fan will most likely never go out of style. Even with central air conditioning systems, and window mounted air conditioners, ceiling fans are still the most affordable way of getting air to move and circulate. With many different sizes, designs, and styles, ceiling fans can be used both indoors and outdoors, and work well in a small apartment or a large factory.
