The R3G220-RN12-01 from EBM Papst is a DC centrifugal fan with backward-curved blades, designed for demanding ventilation and process air applications. The fan combines RadiCal technology with an integrated EC motor for high efficiency and compact dimensions of 220×220×85 mm. With an airflow of up to 1185 m³/h, it delivers impressive performance in a small format.
The fan is ideal for applications requiring quiet, energy-efficient, and reliable operation—for example, in industrial ventilation, air handling units, and electronics cooling. The EC motor allows for easy speed control via 0–10 V DC or PWM signal.
- Voltage: 24 V DC (range 16–28 V DC)
