🔧 Construction & Operation
The W2E143-AB09-01 is an axial fan with a circular aluminum body and steel impeller, a configuration particularly suitable for industrial applications.
The single-phase motor uses the 0.75 µF capacitor specified directly on the nameplate. The integrated thermal protection operates in the event of abnormal motor temperature conditions.
The ball-bearing system is designed for continuous operation and applications requiring reliability and adequate ventilation capacity.
⚡ Function in the Cooling System
The fan generates a high-volume axial airflow, allowing heat produced by internal equipment components to be removed.
With approximately 420 m³/h at 50 Hz and up to approximately 500 m³/h at 60 Hz, it is suitable for cooling equipment with significant heat dissipation.
🏭 Applications
It can be used as a cooling fan for:
- Inverters and converters
- UPS and power supply systems
- Electrical switchboards
- Electrical and electronic cabinets
- Industrial power supplies
- Power electronics
- Automation systems
- Industrial machinery
-
Equipment with forced ventilation
The 230 V AC / 50–60 Hz configuration allows direct integration into numerous industrial systems supplied from the mains.
🏗️ Installation
The circular structure of approximately 172 mm diameter and 51 mm depth must be checked against the available space in the equipment.
Electrical connection must be carried out according to the manufacturer's specified wiring diagram and using the appropriate 0.75 µF capacitor.
As this is a 230 V AC component, installation and testing must only be carried out by qualified personnel.
🛡️ Safety & Product Condition
The fan is used and shows normal signs of use, dust, and light superficial marks on the frame and impeller, visible in the photographs.
No significant structural breaks are evident on the housing or impeller.
The nameplate explicitly states “Thermally protected”, meaning that the motor has thermal protection.
Operation is not declared tested based on the photographs alone. Before selling as a working component, it is recommended to verify startup at 230 V AC, current consumption, rotation, bearing noise, and correct operation of the thermal protection.
