Products Description
W.Fans is new large HVLS energry-saving industrial fan based on PMSM (permanent magnet synchronous motor) principle developed by Dawang.With 260N.m torque,the driving force is more stronger and the torque is more stable.Save 30% energy,IE4 high efficiency.The fan diameter from 2.5M to 7.3M,14850m³/min air volume,free maintain for life,no need to change oil and seal. 20-years reliablelife,W.Fans series solves the problem of ventilation and cooling in large spaces with better performance,lower energy consumption and longer life.
Motor system:pmsm 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.

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.
Blade shape- Streamlined variable cross-section
The blade section is from wide to narrow (304-186mm),from thick to thin (43mm-21mm).Adopts the equal chord length principle and relative linear velocity characteristics to ensure the balance pressure of the whole blade to achieve the tip,middle and roots air evenly including the middle.
Blade shape- transverse section,equal width section The blade length is equal with cross section ,blade width is 19CM.High air resistance is not conducive to pushing airflow, holes in the middle, high energy consumption.
Blade material- aviation aluminum sheet Adopt NO.5052H32 1.5mm thickness aviation high grade density aluminum alloy original plate,with high strength and flexibility,bright and durable.
Blade material-Low grade aluminum Low grade aluminum mixed with recycled aluminum for secondary processing, low density, impurities, pores, low toughness and easy to break
Blade weight-light Each blade 6.7KG,total weight for 5pcs 33.5KG.Smaller blades ,lighter weight, reducing the motor load and extend service life, low energy consumption.
Blade weight-heavy Cross section width equal to the blades, Each blade 10KG,normal 6pcs or 8pcs.Heavy weight, large motor load, high energy consumption.
Blade and petiole — full mortise and tenon connection The convex petiole and concave buffer device are locked with bolts, each blade is riveted with buffer device by 16 rivets,forming the blade, buffer device and petiole as a whole, torque and shear less and less.
Blade weight-heavy Cross section width equal to the blades, Each blade 10KG,normal 6pcs or 8pcs.Heavy weight, large motor load, high energy consumption.
Buffer device-Rubber mat The rubber pad between mounting hole of buffer device and shaped inserts to achieve the flexible connection between petiole and chassis.Rubber mat absorb the most of vibration, improve the motor shaft work conditions, extend the life, more quieter
Buffer device-No Vibration cannot be weakened, resulting petiole and blades loosen,heavy loading, high noise.
Wheel chassis-Integrated hub Special-shaped mounting hole and inserts locked each other to prevent the blade from swinging
Wheel chassis structure-die cast Gravity die-casting aluminum wheel chassis or separated wheel hub, low strength, poor fatigue resistance.
