Description
The ebm-papst 4314HR is an industrial-grade compact DC tubeaxial fan engineered in a standard 119 x 119 x 32 mm (4.69 x 4.69 x 1.26 in) plastic frame with an air outlet over struts orientation. Operating on a nominal 24 VDC supply across a flexible 12 to 27 VDC range, the unit delivers a robust airflow of 129.5 CFM (220.0 m³/h) and static back pressure up to 0.498 in H₂O (124 Pa) at 3,650 RPM while consuming 10.8 W. Designed for continuous-duty electronics cooling, it features a heavy-duty ball bearing system, an integrated reverse-polarity protection diode, and an electronic auto-restart locked rotor mechanism. Electrical interconnection is established via 310 mm stranded AWG 22 flying lead wires, ensuring seamless integration into mission-critical power and control systems.
