Description
The ebmpapst R3G133-RA01-03 is a highly advanced RadiCal® EC centrifugal fan engineered for precision ventilation and intelligent airflow management. Powered by the M3G045-AI external rotor motor, this 133 mm backward-curved unit features integrated electronics that allow for direct 200-240 VAC input while providing superior energy efficiency and seamless speed control. The design incorporates a 7-blade PP plastic impeller and a thick-film passivated rotor surface, housed within a durable die-cast aluminum electronics casing. A key technical advantage is its comprehensive suite of electronic features, including a 10 VDC output, Tacho feedback, and a versatile 0-10 VDC/PWM control interface with SELV potential safely disconnected from the supply. Built for S1 continuous operation with IP54 protection, the R3G133-RA01-03 meets stringent EMC standards for both industrial interference immunity and household emission levels, making it the definitive choice for high-end medical devices and compact cleanroom filter units.
