The ACi4400HHAU from EBM-Papst is a compact EC axial fan with a wall ring from the GreenTech EC-Compact series. The fan measures 120 x 120 x 38 mm and is powered directly from the mains voltage within a global voltage range of 100–240 V AC. Its brushless EC motor with integrated converter electronics makes it an energy-efficient and reliable choice for modern ventilation applications.
Thanks to its frequency-independent speed of 3,300 rpm, the fan delivers constant performance regardless of whether the mains frequency is 50 or 60 Hz. This makes it ideal for global use in air conditioning, cooling of electronics cabinets, and industrial ventilation.
- Airflow: 175 m³/h in free air

| Motor frame | The casing is made of glass fiber reinforced PBT plastic and is non-conductive as well as non-flammable. The fan has dimensions of 119 x 119 x 38 mm and weighs 275 g. The maximum protrusion of the rotor is 0.6 mm. |
| Casing | glass-reinforced plastic (PBT), round |
| Impeller | The fan impeller is made of glass fiber reinforced polyamide (PA) and is non-conductive and non-flammable. The airflow is axial with discharge over the support arms. The fan impeller provides an airflow of 175 m³/h at free blowing and a sound pressure level of 43 dB(A) at a distance of 1 meter. |
| Bearing type | ball bearing |
| IP class | IP65 |
| Motor protection | electronically locked rotor protection |
| Motor code | ACi4400HHAU |
| Rotation direction | clockwise as viewed from the rotor |
| Motor type | The EC motor is a highly efficient brushless motor with integrated inverter electronics, enabling direct operation from mains voltage within a global voltage range of 90–264 V AC. The speed is frequency-independent and held constant at 3300 rpm regardless of mains frequency (50 or 60 Hz). The motor is equipped with electronically locked rotor protection and has an IP65 enclosure rating. Compared to an equivalent AC fan, the motor consumes up to 75% less energy and is approximately half the weight. |
