Products Description
W.FANS HVLS ENERGRY-SAVING INDUSTRIAL FAN
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 reliable life,W.Fans series solves the problem of ventilation and cooling in large spaces with better performance,lower energy consumption and longer life.
Dawangfan crash test result: (impacted by forklift ) The blades are still twisted and deformed, does not break or fall. | ||
Others: Common profiles,Rigid connection,fan falling cases | ||
Our Advantages
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.
