Description
The NMB 3110NL-05W-B58 is a high-performance DC axial cooling fan engineered by MinebeaMitsumi specifically for thermal regulation in industrial power electronics and inverter systems. This unit utilizes a precision Dual Ball Bearing architecture, which provides superior longevity and stability compared to sleeve bearing alternatives, making it suitable for continuous operation in vertical or horizontal orientations. The 80mm form factor is optimized to deliver high static pressure, essential for forcing airflow through the dense fin structures of heatsinks in Variable Frequency Drives (VFDs) and power supply units. The housing and impeller are constructed from reinforced PBT plastic, offering resistance to environmental stress and flammability.
