Description
The ebmpapst S4E450-AP01-20/F01 is a high-performance 230VAC single-phase AC axial fan featuring an impeller size of 450 mm and external dimensions of 478 x 478 x 204 mm. Powered by an M4E074-GA motor, this sickle-shaped blade axial fan (S series) with a short nozzle guard grille delivers high-volume airflow and reliable thermal management. Operating at a rated speed of 1,400 / 1,600 RPM under 50 / 60 Hz, it draws a maximum current of 1.1 / 1.55 A with a power consumption of 245 / 355 W and utilizes an integrated 8 µF / 400 VDB motor capacitor (S0 safety class). Built with black-painted sheet steel blades, a phosphated and black-plastic coated steel guard grille, precision ball bearings with low-temperature lubricant, and an IP44 protection rating, it weighs 7.3 kg and supports continuous S1 operation across ambient temperatures ranging from -40 to +40 °C.
