Project technical request and model preparation
On July 31, 2026, LONGWELL opened a project to provide technical specifications for two 500 mm AC axial fan configurations based on models LWAA4E500S-5MEB-16 and LWAA4E500S-5MEB-19, with an estimated quantity of 50 units. The engineering team assigned internal part numbers LWAA4E500S-5MYB-16-00 and LWAA4E500S-5MYB-19-00.

Documented fan specifications
Engineering specification sheets were generated on July 31, 2026. Both designs feature single-phase 220 VAC motors operating at 50 Hz, equipped with IP54 protection and Class F insulation.

|---|---|---|
| Nominal Voltage | 220 VAC | 220 VAC |
| Frequency | 50 Hz | 50 Hz |
| Speed | 1380 rpm | 1380 rpm |
| Current | 1.6 A | 2.1 A |
| Power Input | 370 W | 450 W |
| Maximum Airflow | 6515 m³/h (3832 CFM) | 7468 m³/h (4393 CFM) |
| Capacitor | 8 μF | 15 μF |
| Noise Level (LpA) | 69 dB(A) | 70 dB(A) |
| Operating Temperature | -30°C to 60°C | -30°C to 60°C |
Mechanical features and output
Both models feature cold-rolled sheet impellers and maintenance-free deep groove ball bearings, suitable for horizontal or vertical installation. The technical specifications and drawings were output for model evaluation.
