The R3G280-RN30-01 from EBM-Papst is a DC-powered centrifugal fan with backward-curved RadiCal blades, designed for demanding ventilation and air handling applications. Powered by a 24 V DC EC motor, the fan delivers an airflow of 1,400 m³/h at its optimal efficiency point. With its compact design and IP44 rating, it is well-suited for industrial and unit environments.
Thanks to EC motor technology, the fan offers energy-efficient operation with integrated soft start and power limitation. It is ideal for air handling units, heat pumps, and ventilation systems where reliable and quiet centrifugal ventilation is required.
- Airflow: 1,400 m³/h at 239 Pa static pressure
- Supply voltage: 24 V DC (range 16–28 V DC)
- Power consumption: 142 W, current draw 5.9 A
- Speed: 1,900 rpm, clockwise rotation when viewed toward the rotor
- EC motor M3G074-CF with soft start, power limiter, and tach output
- RadiCal impeller, 280 mm, 6 blades in PP plastic
- Protection class IP44, ball bearings, sound pressure 67 dB(A)
- Electrical connection via PVC cable AWG16 with crimped ferrules
