Description
The ebm-papst 4314HR-312 is a high-performance DC axial compact fan engineered for rigorous industrial thermal management. Operating within a wide voltage range of 12VDC to 28VDC (24VDC nominal), this unit delivers a substantial airflow of 170m3/h at a rated speed of 2800RPM. It features a robust glass-fiber reinforced PBT plastic housing and PA plastic impeller, ensuring structural integrity under thermal stress. With a power consumption of 5.0W and a noise emission level of 45dB(A), it balances high-volume air displacement with operational efficiency. The integrated ball bearing system supports an extended service life of 62,500 hours at 40°C, while electronic commutation provides essential protection against reverse polarity and rotor blockage.
