Description
The ebmpapst K3G250-AV29-B2 is a powerful and energy-efficient 230V AC EC centrifugal fan with backward-curved blades, functioning as a motorized impeller. With an impeller diameter of 250mm, it features a nominal voltage range of 200V to 277V AC and operates at 50/60Hz. At its maximum load, it consumes 750W of power, drawing 3.3A of current, and spins at 3450 RPM. This fan delivers a substantial airflow of 1755 m³/h and operates with a noise level around 63 dBA. It is rated IP54 for protection, features robust ball bearings, and uses an aluminum impeller, making it highly suitable for demanding applications in air conditioning units, wind power inverters, and general industrial ventilation requiring precise speed control and high efficiency.
