A4E450-CP01-31: Large-Scale Industrial Ventilation
The W4E450-CP01-31 is a robust 450mm axial fan designed for high-volume air movement in the most demanding industrial settings. This single-phase AC unit is a benchmark in the refrigeration and heat exchange industry, often found in large evaporator units and cooling towers. The sickle-shaped blades are aerodynamically optimized to move massive amounts of air (over 5000 m3/h) while maintaining a surprisingly low acoustic footprint. The external rotor motor design allows the motor to be cooled by the very air it moves, significantly increasing the service life of the internal components and ensuring reliability in 24/7 industrial duty cycles.
Key Technical Characteristics
- Nominal Size: 450 mm.
- Voltage: 230 VAC (Single-phase).
- Input Power: 250W – 350W.
- Material: Sheet steel impeller, painted black for corrosion resistance.
- Bearings: Maintenance-free ball bearings.
Engineer’s Field Notes & Diagnosis
Lifecycle State: Active. This model is a standard for retrofitting older industrial coolers. Diagnostic Tips: If the fan stops intermittently, check the internal thermal overload protector (TOP). It may trip if the ambient temperature exceeds 65°C or if the backpressure is too high, causing the motor to work outside its curve. Maintenance: Quarterly cleaning of the blades is recommended; even 100g of dust can unbalance a 450mm impeller. Compatibility: Works perfectly with WinCC for status monitoring. It can be integrated into Siemens SIMATIC S7 PLC systems using a standard AC motor starter or a variable speed controller to optimize energy consumption during low-load periods.

Technical Tip
Always verify the capacitor capacitance during annual maintenance. A weak capacitor will increase motor heat and eventually lead to winding burnout in fans of this diameter.
