Industrial axial fan for 400V AC systems
This 250 mm axial fan runs on three-phase 400 V AC at 50 or 60 Hz and delivers 225 m3/h at 2750 RPM. It is built for machinery, HVAC enclosures and inverter cooling where a compact metal housing and IP00 rating are specified.
Check voltage, phase and mounting before ordering
The unit requires a 380–415 VAC three-phase supply and draws 0.27 A at 50 Hz or 0.33 A at 60 Hz. Verify that your wiring, protection class and the 250 mm cutout match the sheet-steel housing and guard grille dimensions.
Thermals, noise and power in normal use
At 50 Hz the motor consumes 120 W and spins at 2750 RPM; at 60 Hz it rises to 190 W and 3050 RPM. Ball bearings and insulation class B allow continuous operation from -25 °C to 75 °C ambient. The IP00 housing means the installer must provide fingertip and dust protection.

Questions about this item
What comes in the package and is any wiring or mounting hardware included?
The package contains one fan unit only; no cables, connectors or mounting brackets are supplied.
How do I decide between the 50 Hz and 60 Hz operating points for this 400 VAC three-phase fan?
At 50 Hz the fan runs at 2750 RPM, draws 0.27 A and delivers 120 W; at 60 Hz it runs at 3050 RPM, draws 0.33 A and delivers 190 W — choose the point that matches your supply frequency.
What does the 2750 RPM figure mean once the fan is installed in a cabinet?
At 50 Hz the motor spins at 2750 RPM, producing 225 m³/h airflow against a maximum back pressure of 115 Pa with five steel blades in an IP00 housing.
