Quality Control of Critical Components

From raw material procurement to product shipment, every single process in our company is strictly subject to quality control according to ISO9001 standards. In particular, critical components such as motors, hubs, and blades are subjected to even more rigorous inspection.

The motor配套 with the fan can be selected from well-known domestic brands, and it is equipped with SKF, FAG, or NSK bearings, thereby ensuring the long service life of the fan’s power system.

After the impeller hub is completed, it undergoes both static and dynamic balance tests, and a detailed report is prepared. The dynamic balance grade is G5.6, which exceeds the national industry standard requirement of G6.3, thereby ensuring smooth operation of the fan and extending the service life of the motor bearings.

Every process—from material selection and stamping to installation and commissioning—is rigorously controlled, with multiple layers of quality inspection at each stage, ensuring the blades meet both quality standards and operational requirements.
