A4E420-AU03-01 ebmpapst 230VAC 420mm AC Axial Fan

Description

The ebmpapst A4E420-AU03-01 is a high-performance 230VAC single-phase AC axial fan featuring an impeller size of 420 mm. Powered by an M4E094-EA motor, this sickle-shaped blade (S series) axial fan delivers reliable airflow and static pressure performance. Operating at a rated speed of 1,360 / 1,520 RPM under 50 / 60 Hz, it draws a maximum current of 1.25 / 1.68 A with a power consumption of 280 / 385 W and utilizes an integrated 7 µF / 450 VDB motor capacitor. It achieves an air flow of 3,205 m³/h at 100 Pa with a max back pressure of 95 / 100 Pa (0.38 / 0.4 in. wg). Constructed with press-fitted sheet steel blades sprayed with PP plastic, precision ball bearings, and an IP54 protection rating, it weighs 4.8 kg and supports continuous S1 operation across ambient temperatures ranging from -40 to +55 °C.
