Product Description
high volume low speed fans for large plant air ventilation-PMSM motor,maintenance-free for life
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.

Dynamical system:PMSM motor Dawang motors,free maintenance Small size: 1/3 of traditional gear motor Low noise:less 40% than traditional gear motor Low energy:min 30% saving than traditional gear motor Low temperature: less than 1310F | |
| VFD:Vector Converter 1.Start steady: Motor vector algorithm and current suppression to achieve 2.No noise: up to 16KHZ, 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 when 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 84.9Ibs.more safe | |
Wheel Hub(chassis): 7075 aviation aluminum plate after CNC precision machining,perfect appearance and metal streamline to ensure the mechanical performance.After machining, max tolerance is 100μm, to ensure the dynamic balance. |
| Blade shape- Streamlined variable cross-section | Blade shape- transverse section,equal width 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. | 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 | Blade material-Low grade aluminum |
| Adopt NO.5052H32 1.5mm thickness aviation high grade density aluminum alloy original plate,with high strength and flexibility,bright and durable. | Low grade aluminum mixed with recycled aluminum for secondary processing, low density, impurities, pores, low toughness and easy to break |
| Blade weight-light | Blade weight-heavy |
| 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. | Cross section width equal to the blades, Each blade 10KG,normal 6pcs or 8pcs.Heavy weight, large motor load, high energy consumption. |
