Specification request and model scope
On July 30, 2026, LONGWELL opened a project to prepare technical specifications for AC axial fan configurations including LWAA2D200S-5MEB-38, LWAA2E300S-5MEB-09, and LWAA2D300S-5MEB-33. On July 31, 2026, LONGWELL engineering issued technical specifications and drawings for fit and system evaluation.
Documented AC axial fan parameters
The engineering documentation establishes electrical ratings, maximum free-air delivery, physical dimensions, and operational limits for the specified AC axial fan models. The table below outlines parameters specified in the technical datasheets:

Drawing and mechanical details
Model LWAA2D200S-5MEB-38-00 features a 200 mm axial impeller fabricated from cold-rolled sheet metal with a guard grille mounting dimension of 260 mm (+2/0 mm tolerance). The 380 VAC 3-phase unit operates under continuous S1 duty and utilizes maintenance-free deep groove ball bearings. Model LWAA2E300S-5MEB-09-00 integrates a 300 mm cold-rolled sheet impeller within a guard ring measuring 360 mm (+2/0 mm tolerance) across mounting points. Both designs allow horizontal or vertical mounting orientations.
LONGWELL completed and reviewed the revised drawing and model files on July 31, 2026, delivering the updated specifications to support customer fit evaluation.
