Description
The ebmpapst 612NHHR-147 is a high-performance 12VDC DC Axial Fan with dimensions of 60 x 60 x 25 mm, featuring a glass-fiber reinforced PBT housing and a 54 mm glass-fiber reinforced PA plastic impeller, specifically engineered for mission-critical cooling in Industrial Frequency Converters. Driven by a brushless external rotor motor with maintenance-free ball bearings and any-shaft mounting position, this 0.066 kg unit operates at 12 VDC delivering a Max. Power Consumption of 2.9 W and a Max. Current Draw of 0.24 A at a rated speed of 6800 RPM. This High-performance unit achieves a Max. Air Flow of 32.37 CFM (55.0 m³/h / 0.92 m³/min) and a Max. Static Pressure of 14.28 mmH₂O (140.0 Pa / 0.56 inAq). Featuring integrated electronic protection against reverse polarity and blocking, alongside AWG 24 leads, this unit is optimized for industrial VFD systems requiring high-velocity airflow and long-term reliability at the end.
