4418H ebmpapst 48V 0.18A 8.6W 119mm 12038 DC Axial Fan

Description

The ebmpapst 4418H is a high-performance 48V DC Axial Fan with dimensions of 119 x 119 x 38 mm, engineered for powerful cooling in demanding electronic environments. Operating within a wide voltage range of 36-60 VDC, this unit delivers a substantial airflow of 240 m³/h (141.3 CFM) at a rated speed of 4300 RPM. Optimized for high-velocity heat dissipation, it consumes 8.6 W with a current draw of 0.18 A. The fan features a glass-fiber reinforced PBT plastic housing and a PA plastic impeller, utilizing a high-precision ball bearing system for a service life of 57,500 hours at 40 °C. Equipped with integrated electronic protection against reverse polarity and blocked-rotor conditions, the 4418H is a mission-critical thermal management solution for 48V telecommunications racks, high-capacity power supplies, and industrial server enclosures.
