The G3G146-AB72-01 from EBM-Papst is an EC-driven centrifugal fan with a 146 mm forward-curved impeller, designed for demanding ventilation and blower applications. The fan is powered by a single-phase EC motor type M3G074-CF with a nominal voltage of 115 V AC, delivering up to 590 m³/h at free air flow. The housing is made of cast aluminum, providing excellent mechanical stability and efficient heat dissipation.
The fan is well-suited for air handling units, industrial machines, and ventilation systems where energy-efficient and quiet operation is important. The EC motor's built-in soft start and motor current limitation reduce wear and extend service life.

|---|---|
| Airflow at 0 Pa | 590 m³/h |
| Speed | 2390 rpm |
| Power | 170W |
| Frequency | 50/60 Hz |
| Voltage | 115 V AC VAC |
| Motor frame | The fan is supplied with a cast aluminum housing with a flange for easy mounting. The standard mounting position is shaft horizontal or rotor upwards; rotor downwards is possible on request. The die-cast aluminum housing provides good mechanical stability and heat dissipation. The cable outlet is variable for flexible installation. |
| Casing | Cast aluminum |
| Impeller | The fan impeller is a forward-curved, single-inlet hot-dip galvanized sheet steel, size 146 mm. It is designed for centrifugal fan applications and provides a maximum airflow of 590 m³/h at free air flow. The impeller rotates clockwise when viewed towards the rotor and is designed for operation in the housing with a flange. The material provides good corrosion resistance thanks to the hot-dip galvanization. |
| Bearing type | ball bearing |
| IP class | IP44 |
| Motor protection | Thermal overload protector (TOP), internally connected |
| Motor code | M3G074-CF |
| Rotation direction | clockwise, viewed from the rotor |
| Motor type | The motor is an EC motor, type M3G074-CF, single-phase with a nominal voltage of 115 V AC and a frequency of 50/60 Hz. It has a power consumption of 170 W and a rated current of 2.1 A at a nominal speed of 2390 rpm. The motor is equipped with internally connected thermal overload protection (TOP) and monitored electronics with soft start and motor current limitation. Insulation class B is applied, and the operating mode is continuous duty (S1). Control is via 0–10 V DC or PWM signal. |
