W6E400-CP02-31: Specialized Low-Noise Ventilation
The W6E400-CP02-31 is a unique 6-pole axial fan designed for applications where noise reduction and moderate airflow are prioritized over high-speed air movement. The 6-pole motor configuration allows the fan to operate at a lower RPM (typically around 900 RPM), making it exceptionally quiet and ideal for environments such as hospitals, data centers, and commercial HVAC units where acoustic comfort is paramount. Despite its lower speed, the 400mm impeller provides a consistent and stable airflow, ensuring that thermal management targets are met without the turbulence associated with 4-pole models. The rugged die-cast aluminum housing and sheet steel blades ensure it meets industrial durability standards.
Technical Specifications
- Diameter: 400 mm.
- Motor Type: 6-pole AC motor.
- Voltage: 230 VAC.
- Airflow Direction: Exhaust over struts (V).
- Protection Class: IP44 with moisture protection.
Maintenance & Diagnosis Guide
Lifecycle State: Active. High demand for acoustic-sensitive cooling projects. Diagnosis: Due to its lower speed, the W6E400-CP02-31 is sensitive to airflow obstructions. If the fan hums or vibrates, check for debris caught in the guard grille or impeller. Installation Advice: Ensure that the mounting is rigid; even though it is a low-noise unit, mechanical resonance at 900 RPM can be problematic in thin-walled housings. Compatibility: It is frequently used in systems managed by Siemens LOGO! or S7-1200. It integrates easily with TIA Portal programmed cycles, allowing for extremely quiet operation during night-time or low-load production cycles in smart facilities.

Maintenance Note
Check the electrical connections for oxidation annually, especially if the fan is used in air-conditioned environments where condensation can occur during off-cycles.
