Abstract
Description
Technical Field
[0001] This utility model relates to the field of axial flow fan technology, specifically a highly stable anti-vibration axial flow fan. Background Technology
[0002] The high-stability, vibration-resistant axial flow fan adopts a direct drive method, with the motor shaft directly connected to the impeller, reducing intermediate transmission components.
