EC cross flow fan specification scope
On August 10, 2026, LONGWELL opened a project to issue Chinese-language technical specification sheets for two EC cross flow fan models: LWCE-80350SN-06-00 and LWCE-80520SN-06-00. The LONGWELL engineering team completed the technical specification drafting and review on August 11, 2026.
This project scope is limited to the technical drawing and specification development stage. The published specification documents establish nominal operational parameters, material construction, and performance limits for system fit evaluation.
Technical specifications
Both models feature aluminum impellers housed in cold-rolled steel frames. They operate on a nominal 230 VAC supply (184–276 VAC range at 50/60 Hz) with counter-clockwise rotation, using ball bearings rated for 30,000 hours of L10 life at 25°C ambient temperature.
