ebmpapst R2E220AA4423 fan

Centrifugal fan EBM-PAPST R2E220AA4423, 377.145.417. Powerful AC fan 75 W with 11-blade impeller for cooling and ventilation systems. Fan EBM-PAPST R2E220-AA44-23 is a high-efficiency centrifugal fan (Motorized Impeller) with backward curved blades and single-sided suction. The model is designed for applications requiring high resistance to contamination and features high hydraulic efficiency due to the well-thought-out design of the working blades. Attention: this model is obsolete, making it especially valuable for replacement on already installed equipment without the need to modify mounting locations. Failure of the standard fan is critical — it leads to overheating and emergency shutdown of equipment. Installing an exact original replacement guarantees quick restoration of system operability.
