4312U ebmpapst 12V 0.5A 119x119x32mm DC Axial Fan

Description

The ebmpapst 4312U is a high-performance 12VDC IP68-rated DC Axial Fan with dimensions of 119 x 119 x 32 mm, featuring a robust glass-fiber reinforced PBT housing and a 112 mm 5-blade PA impeller, specifically engineered for mission-critical cooling in Industrial Frequency Converters. Driven by an electronically commutated external rotor motor with maintenance-free ball bearings, this 0.260 kg unit operates at 12 VDC delivering a Max. Power Consumption of 6.0 W and a Max. Current Draw of 0.5 A at a rated speed of 2800 RPM. This High-performance unit achieves a Max. Air Flow of 100.0 CFM (170.0 m³/h / 2.83 m³/min) and a Max. Static Pressure of 7.95 mmH₂O (78.0 Pa / 0.31 inAq). Fully encapsulated with IP68 protection for continuous immersion and dust-tight performance, this 5-blade unit is optimized for environments requiring extreme reliability and high-static pressure in industrial VFD systems at the end.
