1. The housing is constructed of galvanized steel. The galvanizing process imparts excellent corrosion resistance, ensuring long-term structural stability and extended service life, even in humid and dusty industrial environments.
2. The impeller is constructed of forward-curved galvanized steel. This design ensures efficient airflow under the impeller's propulsion. Combined with the durability of the galvanized steel, it prevents deformation and wear during long-term operation, ensuring consistent airflow output.
3. The motor utilizes an external rotor structure and operates in an AC mode compatible with conventional industrial power sources, ensuring stable and reliable operation. Industrial-grade, high-strength ball bearings significantly reduce friction and noise while extending motor life.
4. The shaft is constructed of carbon steel rod, offering high strength and excellent deformation resistance, providing solid support for the entire fans system.

What Causes Blower Impeller Noise and Vibration? The abnormal noise or vibration in a blower impeller is most commonly caused by physical imbalance (over 70% of field service cases), followed by bearing failure, loose mounting, or foreign object debris. If the impeller is not perfectly balanced, even a slight weight d...
