The 4850ZW from EBM-Papst is a compact AC axial fan with a wall ring, designed for reliable ventilation in protected indoor environments. The fan comes with a 310 mm twin cable and fits into a 119 × 119 × 38 mm frame. With a metal housing and metallic impeller, it offers both robustness and long operating life.
The fan is ideal for electrical cabinets, control systems, and temperature-controlled industrial environments where quiet and efficient cooling is required. Its low sound pressure level of 27 dB(A) makes it a natural choice where acoustic comfort is important.

|---|---|
| Airflow at 0 Pa | 98 m³/h |
| Speed | 1700/1800 rpm |
| Power | 13 W |
| Frequency | 50/60 Hz |
| Voltage | 230V AC VAC |
| Motor frame | The fan has a metal casing with dimensions 119 x 119 x 38 mm and a weight of 0.54 kg. Mounting is done with ISO 4762 M4 screws (degreased, without additional support and without a washer). The torque limit is 120 Ncm at the cable corner and 350 Ncm at the other corners. The mounting position for the shaft is optional, and the unit is intended for protected indoor environments with controlled temperature and humidity. |
| Casing | metal, square |
| Impeller | The fan impeller is made of metal and has a diameter adapted to an 119 x 119 mm frame. Airflow is discharged over the support struts (air outlet over struts). With free air flow, a maximum flow of 98 m³/h at 50 Hz and 104 m³/h at 60 Hz is achieved. The maximum static pressure is 27 Pa at 50 Hz and 24 Pa at 60 Hz. The fan impeller is balanced according to balancing class 2.5. |
| Bearing type | plain bearing |
| Rotation direction | clockwise |
| Motor type | The motor is an AC motor designed for 230 V with a frequency of 50 or 60 Hz. At 50 Hz, the motor delivers 13 W and at 60 Hz, the power consumption is 12 W. The speed is 1700 rpm at 50 Hz and 1800 rpm at 60 Hz. The motor has impedance protection against locked rotor and protection class I. The operating temperature range is -10 °C to 65 °C (50 Hz) and -10 °C to 70 °C (60 Hz) respectively. |
