DW.FANS SERIES
——
DW.FANS series is a vertical HVLS energy-saving fan, which breaks
the installation limitations of traditional industrial large fans
and is suitable for more indoor and outdoor places that require
ventilation and cooling, such as airports, high-speed railways,
amusement parks, bars, restaurants, citizen squares, commercial
complexes, etc.
The DW.FANS series solves the industry problem of outdoor cooling.
Due to the limitations of the site and environment, general
ventilation and air conditioning equipment often cannot function
well outdoors. However, the DW.FANS series energy-saving fans are
more suitable for ventilation and cooling equipment in this
environment, which can create a comfortable feeling close to
natural wind.

DW.fans Series Fan Features
——
Power system : pmsm permanent magnet synchronous motor
Maintenance-free fully sealed motor
1. Small size : the volume is 1/3 of the traditional motor
2. Low noise : 40% lower than traditional motor noise
3. Low energy consumption: more than 30% energy saving than
traditional geared motors
4. Low heat generation : the maximum heat generation of the motor is
less than 55℃;
VFD : Vector Converter
1. Start steady : Motor vector algorithm and current suppression to
achieve
2. No noise : up to 16 KHZ , no noise during speed up , slow down ,
and running
3. Restart : It can smooth restart when the blades not completely
stopped
4. Failure protection : 25 fail-safe protections ( over current ,
over voltage , under voltage phase loss , overload , etc .)
Blade : Streamlined variable cross-section
1.0.059” thickness No.5052 aviation aluminum alloy plate , not
break wher Impact
2.To aerodynamic equal chord length theory, the blade narrows and
thins from root to tip till tail then widen, more uniform
3.17ibs per blade (24ft ) , 5 blades total 84.9 ibs , more safer
Wheel chassis:
1.It is made of 7075 aviation-grade aluminum material by CNC lathe
processing + CNC precision processing technology, the shape
maintains the same height, the metal streamline is complete, and
the better mechanical performance of the chassis is guaranteed.
2.After CNC machining, the precision tolerance of the chassis is
controlled at 100mm to ensure the precise dynamic balance of the
chassis.
Connection:
The key parts are structurally connected to ensure the fan overall
safety:
1.Motor and connecting rod : The motor cover and connecting rod are
equipped with a suspension ring , even if the motor shaft is loose
, the hangingring will snap up and down to prevent falling.
2.Chassis and petiole: The petiole and the chassis are connected by
ahook-type tenon joint , the bolts are not stressed , and the
overall strength is guaranteed.
3.Blade and petiole : The centrifugal force, resistance and
buoyancy generatedby the rotation of the blade are transmitted to
the petiole chassis through the concave-convex tenon and tenon
joint connection , so as to prevent the blade from breaking due to
cutting force.

Core Technology
Blade Design:Streamline Variable Cross-Section
1. Blade design: streamlined variable cross-section
Through aerodynamic simulation analysis, applying equal chord
length theory, combined with the principle of relative linear
velocity, a streamline variable cross-section fan blade was
developed and designed, which gradually narrowed and thinned from
blade root to tip, with more balanced force, more uniform air
supply, and no cavity in the center.
2. Blade Material Selection:Aviation Grade Industrial Alloy Plate
Adopting 5052H32 high grade 1.5mm aviation grade aluminum alloy
motherboard, precision CNC forming, higher strength and
flexibility, ensuring no fracture. Lighter and safer in weight.
Each blade only weighs 6.7 kilograms (7.3 meters in diameter,
excluding buffer parts), with a small number of blades and light
weight, reducing motor load, extending service life, and ensuring
safety and energy conservation.
3. Blade Connection - Multi Point Riveting Process
16 high-strength steel core rivets are separated and riveted up and
down (a single rivet can withstand 1500kg tension), forming
independent surfaces on the upper and lower layers of the blades to
withstand the strong centrifugal force when the fan is running at
full speed.
Patented Buffer Structure : Efficient Fan Components
1. Shock-absorption Rubber
With high-precision coordination with the blade buffer chamber, it
efficiently absorbs stress and airflow vibration from the blade,
reduces motor load, and extends service life.
2. 1 ° Micro Upward
There is a precise angle limit in the buffer chamber, and the blade
handle is connected to the buffer chamber to form a 1 ° micro
upward movement, effectively eliminating the reverse force
generated during the fan operation and forming a conical airflow,
achieving no voids in the center and increasing coverage.
Patent Integrated Hub:the core of fan safety
Patent Integrated Hub
By interlocking the upper and lower pressure plates with the
concave and convex steps of the blade handle, the blade handle is
integrated with the hub/motor, and the overall structure is used to
withstand the centrifugal force during fan operation, without any
stress on all fasteners.
Patent Inner Cone Shaft Sleeve
A patent inner cone kit is installed in the center of the hub,
forming a structural self-locking with the output of the inner
rotor motor, which naturally expands and tightens under the action
of gravity, ensuring reliable connection between the overall hub
and the motor.
Safety Anti Fall Structure
Anti fall ring and inner rotor motor: connect 5 blade handles with
the anti fall ring through bolts, and form a sleeve hanging with
the chassis of the frame to prevent falling due to wheel hub
detachment or shaft breakage;
Anti Fall Ring And Outer Rotor Motor
The anti fall ring forms a collar with the motor flange, ensuring
effective hooking in the event of motor shaft breakage and ensuring
safe operation.
