The R4E310-AO32-17 from EBM-Papst is a centrifugal fan with a backward-curved impeller, designed for demanding ventilation and air handling applications. The fan is powered by a single-phase AC motor operating at 115 V and 60 Hz, delivering an airflow of up to 2025 m³/h in free air. With a robust 310 mm housing and IP44 protection, it is well-suited for industrial environments.
The fan is an excellent choice for air handling units, air conditioning systems, and ventilation solutions where compact design and high air volume are important. The backward-curved impeller with six sheet aluminum blades provides efficient operation with low energy consumption.
