The EBM-Papst R2E190-AE77-C6 is a single-inlet, backward-curved centrifugal fan designed for applications requiring efficient and reliable airflow. This fan is part of the R2E series, known for its compact design due to the impeller mounting directly onto the drive motor, eliminating the need for an external driveshaft. It is engineered for excellent hydraulic efficiency and low noise output, making it suitable for use against medium back pressure. The R2E190-AE77-C6 is intended for use in various sectors including building ventilation, industrial machinery, IT/telecom equipment, medical devices, and transportation systems.
