The W4D450-ZU22-01 from EBM-Papst is a robust axial fan with a panel housing, designed for demanding industrial ventilation. The fan delivers an airflow of 4,125 m³/h and is powered by a three-phase AC motor with automatic reset thermal protection. With an IP54 protection rating and a durable PP plastic casing, it is built to withstand harsh operating environments.
The fan is ideal for large ventilation units, industrial premises, and process equipment where high airflow and continuous operation are required. The three-phase 400 V AC power supply and S1 operating mode make it a reliable choice for installations with long operating times.

|---|---|
| Airflow at 0 Pa | 4125 m³/h |
| Speed | 1200/1400 rpm |
| Power | 495 W |
| Frequency | 50/60 Hz |
| Voltage | 400V AC VAC |
| Motor frame | The fan is designed as a panel fan with an integrated PP plastic housing, mounted via an 8-hole flange on the relevant bolt circle. It can be mounted on the inlet side against a flange or suction nozzle, and on the outlet side against a flange. Recommended fasteners are M6 socket head cap screws (DIN 912/DIN EN ISO 4762). The tightening torque for the fasteners is 1.5 ± 0.2 Nm. Condensate drainage holes are located on the impeller side. |
| Casing | PP plastic, square panel cover with protective grille |
| Impeller | The impeller is made of PP plastic with a galvanized steel plate and has 5 blades. The airflow direction is axial (V) and the direction of rotation is clockwise when looking at the rotor. The rotor surface is painted black to provide a uniform appearance and increased corrosion protection. At the optimal operating point (50 Hz, delta connection, 400 V), the impeller delivers an airflow of 4125 m³/h at a static pressure of 178 Pa. |
| Bearing type | ball bearing |
| IP class | IP54 |
| Motor protection | thermal contact with automatic reset |
| Motor code | M4D094-HA |
| Rotation direction | clockwise, viewed towards the rotor |
| Motor type | The motor is of type M4D094-HA and is a three-phase AC motor with insulation class F. Motor protection is provided by a thermal contact with automatic reset, designed with basic insulation. The motor is equipped with ball bearings and has S1 duty (continuous operation). The enclosure class is IP54 and the motor is integrated into the PP plastic fan housing. |
