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 | ||
Product Description
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.
