4660N ebmpapst 115/230V 119mm AC Axial Fan

Description

The ebmpapst 4660N is a high-performance DC Axial Fan with dimensions of 119 x 119 x 38 mm. This versatile AC axial fan features a dual-voltage, multi-frequency design capable of operating at both 115 VAC and 230 VAC (50/60 Hz) through flexible wiring configurations. Built with a heavy-duty die-cast aluminum housing and a sheet steel impeller, it delivers a maximum airflow of 100.0 CFM (170 m³/h) at 60 Hz. The fan utilizes a precision sleeve bearing system and an impedance-protected external rotor motor, ensuring reliable cooling in demanding industrial environments. It is an ideal thermal solution for control cabinets, power supplies, and high-density electronic racks that require a rugged, all-metal construction and adaptable electrical compatibility.

Application
The 4660N is specialized for high-durability industrial cooling where electrical flexibility is paramount. Its ability to operate across multiple voltages and frequencies makes it a standard component for globally exported machinery, such as industrial control panels, medical imaging systems, and large-scale power conversion units. The all-metal construction provides excellent heat dissipation and fire resistance, while the sleeve bearing ensures smooth operation in both vertical and horizontal orientations. Its high static pressure capability is particularly effective for pushing air through restrictive filters or dense electronic heat sinks in server environments and telecommunication base stations.
