On August 10, 2026, LONGWELL opened a project to prepare technical drawings and product specifications for axial fan model LWA-350(14″)U(S)M-03. The inquiry requested detailed product dimensions, specifically highlighting the impeller diameter and outer casing diameter, while noting that airflow parameters could be omitted initially.

Engineering Specification and Mechanical Layout
LONGWELL engineering prepared technical drawing documentation under model designation LWA-350(14″)SM-03. The resulting drawing specifies a full metal body casing for industrial use and an axial fan layout operating on a 220V 50Hz single-phase AC supply. The technical review stage was completed on August 12, 2026.
