The 4656ZW from EBM-Papst is a robust AC axial fan with a wall ring, built for reliable and efficient ventilation. With a compact metal housing measuring 119 × 119 × 38 mm and an airflow of up to 152 m³/h at 50 Hz, it delivers impressive performance in a small form factor. The fan is designed for 230 V AC and operates at both 50 and 60 Hz.
Thanks to its optional mounting position and robust metal construction, the 4656ZW is ideally suited for industrial and OEM applications that require reliable air circulation – for example, in cooling electrical cabinets, units, and telecommunication equipment.

|---|---|
| Airflow at 0 Pa | 152 m³/h |
| Speed | 2650/3100 rpm |
| Power | 19 W |
| Frequency | 50/60 Hz |
| Voltage | 230V AC VAC |
| Motor frame | The fan has a square metal casing measuring 119 x 119 x 38 mm and weighs 0.54 kg. ISO 4762 - M4 mounting screws (degreased, without washer) are used for fastening. The maximum tightening torque during mounting is 120 Ncm at the cable outlet corner and 350 Ncm at the other corners. The mounting position for the shaft is arbitrary. |
| Casing | metal |
| Impeller | The fan impeller is made of metal and is balanced according to balancing class 2.5. Airflow occurs with air discharge over the struts. At 50 Hz and free airflow, a maximum flow of 152 m³/h and a maximum static pressure of 70 Pa are achieved. At 60 Hz, a maximum flow of 180 m³/h and a maximum static pressure of 80 Pa are achieved. |
| Bearing type | ball bearing |
| Motor protection | impedance protection (locked rotor) |
| Rotation direction | clockwise |
| Motor type | The motor is an AC motor with impedance protection against locked rotor. It operates at 230 V and frequencies of 50 Hz and 60 Hz, respectively. At 50 Hz, the power consumption is 19 W, and at 60 Hz, it is 18 W. The motor belongs to protection class I and complies with standards DIN EN 60950 and DIN EN 60335. The service life (L10) at 40 °C is 37,500 hours at 50 Hz and 40,000 hours at 60 Hz. |
