424JN ebmpapst 24V 0.18A 40x40x28mm DC Axial Fan

Description

The ebmpapst 424JN is a high-performance 24VDC IP68-rated DC Axial Fan with dimensions of 40 x 40 x 28 mm, featuring a glass-fiber reinforced PBT housing and a fully encapsulated motor designed for mission-critical cooling in Industrial Frequency Converters and high-density electronic systems. Driven by a specialized high-speed brushless external rotor motor with maintenance-free ball bearings and complete environmental protection, this 0.045 kg unit operates at 24 VDC delivering a Max. Power Consumption of 4.3 W and a Max. Current Draw of 0.18 A at a rated speed of 14250 RPM. This High-performance unit achieves a Max. Air Flow of 31.0 m³/h (18.2 CFM / 0.52 m³/min) and a Max. Static Pressure of 21.41 mmH₂O (210.0 Pa / 0.84 inAq). Featuring a “Made in Germany” robust construction with IP68-rated moisture and salt spray protection, this unit is optimized for environments requiring extreme reliability and high-static pressure in industrial VFD systems at the end.
