The 4188NXM from EBM-Papst is a robust axial fan with a wall ring for DC voltage, in the 119 × 119 × 38 mm format. The fan is designed for operation in the voltage range 36–60 V DC and delivers an airflow of 148 m³/h – a strong option for demanding ventilation applications. With its metal housing and ball bearings, it is built for long and reliable operation.
The fan is ideal for industrial and technical environments where stable cooling or ventilation is required, for example in electrical cabinets, server environments, and industrial equipment. The motor's built-in reverse polarity protection and automatic restart in case of locked rotor reduce the risk of downtime.

|---|---|
| Airflow at 0 Pa | 148 m³/h |
| Speed | 2800 rpm |
| Power | 3.5 W |
| Voltage | 48 V DC VAC |
| Motor frame | The housing is square with dimensions 119 × 119 × 38 mm and is made of metal. Mounting is done with ISO 4762 M3 screws without washers. The maximum torque for mounting is 170 Ncm for the corner at the cable outlet and 300 Ncm for the other corners. The mounting position for the motor shaft can be in any orientation. |
| Casing | metal |
| Impeller | The impeller is made of plastic and rotates clockwise when viewed from the rotor side. Air is drawn in over the struts (air intake over struts). At the nominal speed of 2800 rpm and free air flow, a maximum flow of 148 m³/h and a maximum static pressure of 80 Pa are achieved. |
| Bearing type | ball bearing |
| Rotation direction | clockwise |
| Motor type | The motor is a DC motor with ball bearings and automatic restart in case of locked rotor. It has built-in reverse polarity protection via a rectifier diode and limited leakage current of max 50 µA at rated voltage. The rated voltage is 48 V DC with a voltage range of 36–60 V. The motor lacks external electronic control signal functionality. |
