4112NH4 ebmpapst 12V 2.66A 119x119x38mm DC Axial Fan

Description

The ebmpapst 4112NH4 is an ultra-high-performance 12 VDC axial compact fan featuring a 119 mm aerodynamic impeller designed for intense thermal management in high-density electronic environments. Driven by a massive 2.66 A brushless DC motor, this unit is engineered for maximum air displacement, delivering an exceptional airflow at a rated speed of 6800 RPM with a power consumption of 32 W. The robust design features a die-cast aluminum housing and a glass-fiber reinforced plastic impeller, ensuring superior structural rigidity and heat dissipation under high-torque operation. As a specialized two-wire version, it is designed for direct-power applications requiring constant, high-velocity cooling. Equipped with premium ball bearings and electronic protection against reverse polarity and locked-rotor conditions, the 4112NH4 offers a professional-grade thermal solution for server racks and industrial power systems across an ambient temperature range of -20 °C to 65 °C.
