S4E450 8317078900 ebmpapst 230V 450mm AC Axial Fan

Description

The ebmpapst S4E450 (8317078900) is a high-performance industrial single-phase AC Axial Fan with an impeller size of 450 mm. Operating on a nominal 230 VAC, this robust air mover is powered by the specialized M4E074-GA external rotor motor. It is engineered for high-efficiency air displacement in HVAC systems, delivering a rated speed of 1400 RPM (50 Hz) or 1600 RPM (60 Hz). The S4E450 is characterized by its balanced power profile, with a maximum input of 355 W and a mechanical output of 220 W at 60 Hz, ensuring stable performance against a maximum static pressure of 85 Pa. Weighing 7.3 kg and built with a 5-blade sheet steel impeller, this unit is a mission-critical thermal management solution for 230V environments such as commercial condensers and industrial ventilation units requiring high-reliability S1 continuous operation.

Application
The ebmpapst S4E450 (8317078900) is primarily utilized in medium-to-large scale refrigeration condensers, heat pumps, and industrial air-cooling units. Its 450 mm sheet steel impeller is specifically optimized to provide efficient airflow at 1400 RPM, balancing high air volume with moderate static pressure (85 Pa) to overcome filter or coil resistance. The M4E074-GA motor’s dual-rated 50/60 Hz capability makes it ideal for global export equipment. With a robust 7.3 kg construction and internal thermal protection, the S4E450 ensures consistent, 24/7 heat rejection in 230V single-phase HVAC infrastructure, safeguarding critical components in agricultural, commercial, and industrial thermal management systems.
