Description
The SANONDA KF4056H12B is a specialized industrial axial fan designed for high-density thermal management applications requiring significant static pressure. Engineered with a robust 40x40x56mm deep-frame architecture, this unit integrates a high-torque DC motor capable of sustaining a 1.5A current draw, delivering exceptional airflow throughput against high system impedance. The mechanical design features precision dual ball bearings to ensure rotational stability and longevity under continuous high-load operation, mitigating vibration and structural fatigue. Its aerodynamic blade configuration is optimized to minimize turbulence while maximizing pressure generation, making it ideal for overcoming the thermal resistance found in tightly packed server chassis and industrial enclosures. The unit includes built-in thermal protection circuitry to safeguard the motor windings against overheating.
