The A3G800-BA77-51 from EBM-Papst is a powerful EC axial fan with HyBlade technology, measuring 800 mm, designed for demanding ventilation projects with high requirements for efficiency and operational reliability. The fan is driven by the M3G112-EA EC motor for three-phase 400 V AC operation and delivers up to 8,365 m³/h with a noise level of only 54 dB(A). Thanks to its IP55 protection class and die-cast aluminum housing, it is built for harsh environments.
The fan is perfectly suited for large-scale ventilation systems, air handling units, and industrial cooling where energy efficiency and smart control are crucial. Its built-in PID controller, soft start, and support for RS-485 MODBUS-RTU, as well as 0–10 V DC/PWM control input, make it easy to integrate into modern control systems.

| Speed | 520 rpm |
| Power | 275 W |
| Frequency | 50/60 Hz |
| Voltage | 400V AC VAC |
| Motor frame | The fan measures 800 mm and weighs 8.75 kg. The standard mounting position is shaft horizontal or rotor downwards; rotor upwards is possible upon request. Condensate drain holes are located on the rotor side. The maximum screw play during mounting is 16 mm, and the tightening torque for the cable glands is 1.8 ± 0.3 Nm and 1.5 ± 0.2 Nm, respectively, depending on the connection point. |
| Casing | Die-cast aluminium, black lacquered; terminal box in PP plastic |
| Impeller | The fan impeller is an EC axial fan impeller of the HyBlade type, with 5 sickle-shaped blades from the S-series. The blades are made of pressed sheet metal (bright) and injection-molded with PP plastic, with the rotor painted black. The airflow direction is marked V, and the fan impeller rotates clockwise when viewed from the rotor. At nominal operating conditions (max load), the fan delivers 7150 m³/h at 55 Pa back pressure and 520 rpm. |
| Bearing type | sealed bearings |
| IP class | IP55 |
| Motor protection | Thermal overload protection (TOP), internally connected |
| Motor code | M3G112-EA |
| Rotation direction | clockwise, looking towards the rotor |
| Motor type | The motor is an EC motor (electronically commutated) of type M3G112-EA for three-phase operation (3~) with a rated voltage of 400 V AC (range 380–480 V AC). It has insulation class F and environmental protection class H2. The motor is equipped with an integrated PID controller, soft start, PFC (passive), RS-485 MODBUS-RTU communication, and 0–10 V DC/PWM control input. Thermal overload protection (TOP) is internally connected, and the electronics housing material is black-painted cast aluminum. |
