The R1G280-RC71-02 from EBM Papst is a DC centrifugal fan with backward-curved blades, designed for demanding industrial applications. The fan is powered by a 24 V DC EC motor (M1G074-CF) and delivers impressive performance in a compact 294×294×138 mm package. The housing is made of die-cast aluminum with a black painted finish for long life and durable construction.
Thanks to the high ingress protection rating of IP6K9K for the electronics and IP24KM for the motor, the fan is well-suited for environments with high demands on sealing and operational reliability. The RadiCal impeller with 7 PP blades provides an airflow of up to 2035 m³/h and smooth, quiet operation with a sound pressure of 63 dB(A).
