Application engineering note
The LONGWELL LWAA2E250B-5MEB-19-00 is an AC axial fan. Its A0 specification gives a concrete starting point for equipment design or a replacement enquiry. Match the complete model suffix and electrical requirements before comparing mounting dimensions.
Values on the model specification
| Parameter | Specified value |
|---|---|
| Nominal supply | 220 VAC, 60 Hz |
| Voltage range | 198–242 VAC |
| Speed | 2600 rpm |
| Input power and current | 130 W, 0.65 A |
| Maximum airflow | 1854 m³/h |
| Capacitor | 3 µF |
| Protection and insulation | IP44, Class F |
The maximum-airflow entry should be checked against the fan curve at the equipment’s actual resistance. Guards, heat exchangers and restricted openings are part of that airflow path.
Check the mechanical and electrical interfaces
Compare the mounting-hole pattern, fan depth, airflow direction and cable exit with the equipment drawing. Include the space needed for wiring and service access. The specification identifies an aluminium-magnesium alloy impeller and permits horizontal or vertical installation.
Use the model-specific wiring diagram and the stated capacitor requirement when preparing the electrical design. The sheet’s supply is 60 Hz; a different frequency needs a corresponding specification review. Confirm the current drawing revision before committing the fan to an equipment bill of materials.
