The R3G133-RA01-03 from EBM-Papst is a compact centrifugal fan with backward-curved blades, designed for demanding ventilation applications. The fan is powered by an EC motor and delivers an airflow of up to 280 m³/h at free flow. With an IP54 protection class and a robust die-cast aluminum casing, it is also suitable for tougher environments.
The fan is well-suited for integration into air handling units, electronics cooling cabinets, and industrial ventilation. The optional mounting position makes installation simple and flexible.
