The R3G190-RC11-04 from EBM-Papst is a compact EC centrifugal fan with backward-curved blades, designed for demanding ventilation applications where efficiency and operational reliability are crucial. The fan combines a RadiCal impeller made of PP plastic with an electronically commutated EC motor, resulting in low energy consumption and excellent control capabilities. With an IP54 protection class and a cast aluminum construction, it is built for harsh environments.
The fan is ideal for air handling units, cooling of electronic cabinets, and industrial ventilation where variable control via 0–10 V DC or PWM signal is required. Optional mounting positions provide great flexibility during installation.

| Motor frame | The fan is designed for mounting in any position. The inlet ring (part number 09576-2-4013) is an accessory not included in the delivery. Maximum clearance for mounting screws is 5 mm. The fan is supplied with PVC AWG20 and AWG22 cables with crimped connections for easy installation. |
| Casing | cast aluminum, the material of the electronics enclosure |
| Impeller | The fan impeller is a RadiCal impeller with backward-curved blades and single-sided intake, made of PP plastic. It has 7 blades and rotates clockwise when viewed from the rotor. The rotor surface is thick-film passivated for increased corrosion resistance. The impeller has a size of 190 mm and is an open rotor design without a condensate drain hole. |
| Bearing type | ball bearing |
| IP class | IP54 |
| Motor protection | Electronic motor protection |
| Motor code | M3G055-BI |
| Rotation direction | clockwise, viewed facing the rotor |
| Motor type | The motor is an EC motor (electronically commutated) of type M3G055-BI, designed for single-phase supply at 115 V AC with a voltage range of 100–130 V AC. It has built-in electronic motor protection with thermal overload protection for both electronics and motor. The motor supports soft start and current limiting, as well as control via 0–10 V DC or PWM signal. Insulation class B and environmental protection class H1 apply to the motor, with a maximum operating ambient temperature of 60 °C. |
