maximum capacity Redesigned fan blade design for optimal balance between performance and smooth operation
Optimized bearing and shaft design (FDB)
Hydrodynamic bearing combined with extended shaft for quieter operation by improving pressure distribution and reducing vibration
Automated balancing
Automated measurement and balancing process ensures exceptional accuracy and smooth operation with balanced mass application with exceptional precision
SOTA microcontroller
Reduces motor noise, compensates for load fluctuations, and protects against inrush currents and reverse polarity
More power – less noise
The fan delivers higher performance at low speeds with greater airflow and static pressure at only 25 dB(A) – ideal for quiet and powerful cooling
Minimal slot dimensions for maximum efficiency Enables greater static pressure and maximum airflow efficiency
