10+ SAFETY GUARANTEE

STREAMLINED VARIABLE CROSS-SECTION
Conform to aerodynamic equal chord length theory,combined with the relative linear velocity principle,the blade narrows and thins from root to tip till tail then widen,the air is more even and uniform.

AVIATION ALUMINUM PLATE
1.5mm thickness 5052 Ultra-high toughness aviation aluminum plate can load more than 3Ton tensile to ensure the blade can deform quickly and absorb external force effectively, It can prevent the blade from breaking,avoid the damage to the motor and other structural parts reatly.

BLADE HIGH-STRENGTH CONNECTION
Each blade is fixed with the buffer cavity by 16pcs high-strength rivets, each rivet can load 1.5 ton shear force.

BUFFER DEVICE
The blade and petiole flexible connects with buffer device, the rubber absorbs the most vibration from blades when running.

ANTI-FALLING RING
The concave flange are engaged with the convex anti-falling ring each other under the gravity to ensure a reliable connection between the flange and motor.

SAFETY RING
Connect the 5 petioles into a whole to form the sleeve with the frame lower hub to prevent the petioles from falling.

MORTISE AND TENON PETIOLE CONNECTION
The convex petiole with concave buffer device form the Joint engaged,eliminate the centrifugal force from the blades when the fan is running and the shear force when the fan starts and stops.

HIGH-TENSILE STRENGTH PETIOLE
6061-T6 petiole,high strenght,HB90 hardness,it has good corrosion resistance with 205MPa tensile strength.

WIRE ROPE WIND PROTECTION
Mounting bracket and I Beam winded with 1000KG tensile wire rope to prevent sliding and falling.

WIRE ROPE BALANCE PROTECTION
Four wire ropes are fixed with building traction to prevent shaking and falling.

ABNORMAL ALARM SYSTEM
The VFD system comes with accident protection.It will automatically alarm and stop work.

REAL-TIME MONITOR AND INITIATIVE MAINTENANCE
Dawang intelligent remote control system realtime monitor the fan operating parameters,motor temperature rise ,fan horizontal level and so on.

Motor system:PMS motor
1.More stronger:260N.m torque,more stronger,more stabler torque,air volume increases 30%.
2.More efficient:Unique outer rotor high torque design,higher accuracy.
3.More energy saving:30% energy saving,up to IE4 high-efficiency energy-saving standards,GB30253-2013 national energy efficiency new standard.
4.Free maintenance for life :Totally sealed,no need to replace lubricating oil,seals and other accessories,more cost-effective.
5.Lower noise:38db lower noise,more comfortable.
6.Lower temperature:Motor raised temperature lower than 35℃,longer life.
Vfd:Vector converter
1.More steady:New generation of high-reliability IGBT modules,Motor vector algorithm and current suppression let the start more steady.
2.More quiet:Up to 16KHZ,no noise during the speed up, slow down and running.
3.More reliable:PCBA three-proof paint treatment,durable and long life.
4.Restart: It can smooth restart when the blades not completely stopped.
5.Failure protection:More than 25 fail-safe protections (over current and voltage,under voltage,phase loss,overload,etc.)


Blades- Airflow components
1.Blade design-Streamline variable cross-section
Conform to aerodynamic equal chord length theory,combined with the relative linear velocity principle,the blade narrows(304-186mm) and thins(43mm-21mm) from root to tip till tail then widen,the air is more even and uniform.
2.Blade material-Aviation aluminum alloy
1.5mm thickness No.5052H32 aviation aluminum alloy original plate,precision CNC molding,high strength and flexibility ensure the blade not to be broken.
3.Blade weight-More lighter and safer
6.7kg per blade(24ft),less blades,lighter weight,it can reduces the motor load,prolong the life,more safe and cost-efficient.
Connection:Patented full mortise and tenon structural design to ensure the whole fan safety:
1.Blade and petiole
Mortise and tenon connection:
The convex petiole with concave buffer device form the Joint engaged,eliminate the centrifugal force from the blades when the fan is running and the shear force when the fan starts and stops.
The transverse screw is the same direction with fan running track to avoiding the shear in order to ensure the blade will not broken,eliminate the possible Safety hazards radically.
2.Petiole and wheel hub
The petiole and hub/motor are integrated by the stepped concave-convex sections to engage each other.The overall structure is used to withstand the centrifugal force during running,and all fasteners are not stressed.
3.Motor and flange roulette
Safety ring:Connect the 5 petioles and motor upper cover form the whole,adopt the occlusion structural to even the force of the whole fan.
Anti-falling roulette:The concave flange roulette engaged with the convex anti-falling ring each other under the gravity to ensure the reliable connection between the flange roulette and motor.
