Company profile
Jiangsu Dawang Ventilation Machinery Co.,Ltd is the first
artificial intelligence industrial fans manufacturer in China. We
are specializing in design, R & D, production, marketing and
maintenance services for new generation super large industrial
ventilation fans.DAWANGFANS adopts HVLS fan technology by American,
which is the most directly and effective solution to ventilation
and cooling for high volume.
With years of experience and strong technical R & D team, we
always maintained progressiveness in HVLS industry!
Product 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 **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
Product function
1. Ventilation：Our Fans can promote the air circulation, perfect
streamline make users enjoy the **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 *0 years.
5.save energy and reduce consumption:The rated power of whole
machine is 1.5kw, which can cover more than ***0m2 area, energy
consumption is only 0.8 KWH. Compared with small powerful fans and
high-power air conditioners, which reduces your costs greatly
Work principle
After years of dedicated research and exploration, Dawangfans
integrates foreign advanced aviation technology to develop superior
performance propeller fan blade, only need rotating slowly form a
continuous and quiet breeze sir. The slow rotation of uniquely
efficient airfoil-shaped blades creates large airflow pushing down,
thus forming a perfect exhaust of propeller blade. Large airflow
pushed to the ground, forming air layer horizontal movement at a
certain height on the ground to promote the whole air circulation.
The advantage is full coverage of the ground and three-dimensional
circulation of the air.

Dawang fans Security grantee
1.Steel wire rope protection:Connector and universal Beam are
winded with ***0KG tension strength wire rope to prevent the whole
fan from sliding and falling.
2.Steel wire rope balance protection:Four wire ropes are fixed by
balance principle and traction of the building to prevent the fan
from shaking and falling under external force and
airflow.
3.Anti-falling safety ring:Safety ring connects the electric unit
with wheel hub, forming fasten body to preventing the broken shaft
from falling apart
4.Anti-fall self - locking device:The patented output shaft
tensioner device of reducer (inner cone design) forms self-locking
in the case of bolt loosening to ensure the hub and output shaft
are firmly fastened together.
5.Integrated hub:The patented integrated wheel hub is embedded with
5 special-shaped fasteners, which can support exceed *1 tons of
tension by government authority test
6.Mortise and tennon petiole connection:The "convex" shape petiole
and "concave" shape structure of the buffer device are locked with
bolts. Blade, petiole and chassis wheel form integral whole to
avoid cutting force and prevent the blade from upwarp, falling and
waggle
7.Shock absorber:The middle part of blade and petiole is connected
with shock absorber, The special rubber pad can decrease the
vibration caused by blades rotation
8.Blade high strength connection:Each blade is riveted to Shock
absorber with *6 rivets, each rivet can load 1.5 tons shear
force.
9.Avionics anti-impact blade:Adopt 1.5mm thickness ***2 aero-grade
aluminum plate, can loading more than 3 tension force, to ensure
blade will not crack when hit by external forces during
operation
*0.Abnormal alarm system:Control system is equipped with protection
when over-voltage, overload and phase loss. It will automatically
alarm and stop work.
Dawang fans Configuration
