Project technical scope
On July 23, 2026, LONGWELL opened an engineering project to generate standard specification and drawing documentation for an AC axial fan. Engineering responded on July 23, 2026, establishing model LWAA4E500S-5MKB-02-00 to fulfill customer specification requirements for a 500 mm nominal assembly.
Nominal specifications and dimensional profile
The LWAA4E500S-5MKB-02-00 design features a cold-rolled sheet impeller supported by maintenance-free deep groove ball bearings. Designed for horizontal or vertical mounting, the motor provides Class F insulation and IP54 protection under S1 continuous operating duty.
