QG030-303/14 ebmpapst 24V 30mm DC Cross-flow Blower

Description

The ebmpapst QG030-303/14 is a high-performance 24VDC IP68-rated DC Cross-flow Blower with dimensions of 365.4 x 50 x 47.5 mm, featuring a 30 mm diameter impeller and a robust aluminum housing designed for mission-critical cooling in Industrial Frequency Converters and specialized power electronics. Driven by a brushless external rotor motor with maintenance-free ball bearings and a fully encapsulated motor system, this 0.42 kg unit operates at 24 VDC delivering a Max. Power Consumption of 8.7 W and a Max. Current Draw of 0.36 A. This High-performance unit achieves a Max. Air Flow of 140.0 m³/h (82.4 CFM / 2.33 m³/min) and a Max. Static Pressure of 5.10 mmH₂O (50.0 Pa / 0.20 inAq). Featuring integrated electronic protection against reverse polarity and blocking, this IP68-protected unit is optimized for environments requiring high reliability, laminar airflow distribution, and long-term durability in industrial VFD systems at the end.
