Description
The ebmpapst R4E355-AK05-05 is a powerful 230V AC centrifugal fan with backward-curved blades, widely used as a motorized impeller for duct installations. It has an impeller diameter of 355mm and overall dimensions of Ø360mm x 172mm. Operating at 230V AC, its performance varies with frequency: at 50Hz, it consumes 180W of power, drawing 0.8A of current, and spins at 1400 RPM; at 60Hz, it consumes 260W of power, drawing 1.14A of current, and spins at 1600 RPM. This fan delivers a substantial airflow of 1730 m³/h / 1018 CFM at 50Hz and operates with a noise level of 66 – 69 dBA. It is rated IP44 for protection, features robust ball bearings, and utilizes an aluminum impeller with a black-coated rotor surface, making it an ideal medical clean FFU purification fan and suitable for other demanding ventilation tasks.
