W2E250-CE31-01: Performance in Industrial Cooling
The W2E250-CE31-01 is a premium 250mm axial fan designed for high-efficiency air movement in medium-to-large industrial enclosures and refrigeration units. It features a wall ring design in die-cast aluminum, which facilitates easy mounting while providing a robust frame for the powerful AC external rotor motor. This model is engineered to handle higher static pressures than standard compact fans, making it ideal for applications where air must be pushed through dense filters or heat exchangers. The blade geometry is optimized for quiet operation, ensuring that even at maximum RPM, the acoustic impact remains within acceptable industrial limits.
Technical Characteristics
- Impeller Size: 250 mm.
- Voltage: 230 VAC (Single-phase).
- Motor: M2E068-CF.
- Power Input: 115W – 165W.
- Airflow Direction: Exhaust over struts (V).
Lifecycle & Engineering Insights
Lifecycle State: Active. This fan is a common replacement part for high-end HVAC systems and industrial chillers. Diagnosis: A frequent failure point in the field is the external capacitor (check nameplate for µF rating). If the motor hums but doesn’t spin, the capacitor is likely at the end of its life. Installation Advice: Verify that the condensation drainage holes are correctly positioned according to the mounting orientation. Compatibility: Fully compatible with TIA Portal automation logic. Its single-phase design allows it to be used with standard thermal protection switches and can be controlled via simple relay logic or phase-cut speed controllers in Siemens S7-1200 environments.

Maintenance Tip
Clean the blades annually with a soft brush. Accumulated grime on a 250mm impeller can significantly reduce airflow and increase motor temperature.
