Overview
The EBM-Papst 4660N is a compact AC axial fan designed for high-performance industrial cooling and thermal management. This dual-voltage model operates at either 115V or 230V AC, making it adaptable to a wide range of electrical systems. With an 18W power rating and 106 CFM airflow capacity, the 4660N combines efficient cooling with a low-profile footprint, making it suitable for electronics enclosures, HVAC systems, refrigeration units, and heat exchanger applications.
Key Features
- Dual-voltage operation (115V/230V AC, 50/60 Hz) — drop-in flexibility across global installations
- Compact square design: 119mm frame, 38mm depth — space-efficient installation
- Sintec sleeve bearing for reliability and extended service life in continuous-duty applications
- Low noise operation at 51 dB(A) — suitable for climate-controlled and office-proximity environments
- All-metal construction with black-coated steel impeller and die-cast aluminum housing
- 5-blade design delivers consistent airflow through heat exchangers and filtration systems
