The K3G200-BD46-04 from EBM Papst is a compact diagonal module with a centrifugal fan, designed for demanding ventilation and air handling applications. The unit is powered by a 24 V DC EC motor and delivers an impressive maximum airflow of 1,230 m³/h. Its housing dimensions of 225×225×89 mm make it easy to integrate into confined spaces.
Thanks to the diagonal impeller with backward-curved blades, high airflow is combined with a compact height. The module is perfectly suited for applications requiring efficient air circulation, such as cooling units, telecom cabinets, and industrial ventilation equipment.
