Key Considerations for Selecting Low-Noise Axial Fans

What key points should be noted when selecting low-noise axial fans? Incorrect fan models and specifications may compromise normal operation. The critical performance parameters of fans are output power, airflow volume, and operating pressure. What key points should be considered during typical selection?

1. Before selection, understand the fan's production and quality status, such as production types, specifications, and primary applications of different products. Thus, centrifugal fans are often the most convenient initial choice.

2. Select low-noise axial fans with different primary applications based on the physical and chemical properties of the transported vapors. For conveying explosive or flammable gases, use explosion-proof models. When transporting corrosive vapors, choose corrosion-resistant axial fans. For high-temperature environments or transporting high-temperature vapors, heat-resistant types should be selected. Products are categorized into several series based on functionality, accommodating diverse customer requirements.

3. When approximately two fan options appear on the selection characteristic data chart, prioritize the fan with superior efficiency and smaller overall dimensions. For fans with a wider adjustment range, comprehensive comparisons across multiple aspects may be necessary. Make decisions only after careful consideration.

4. If the selected centrifugal impeller diameter significantly exceeds the original fan's diameter, the original motor shaft, rolling bearings, and rubber mounts may be reused. This preserves the motor's structural integrity and critical speed ratio while maintaining the original fan assembly's performance.

5. When selecting low-noise axial fans, minimize the use of fans in series or parallel configurations. If necessary, use fans of identical model and performance specifications. For series configurations, ensure piping connects the primary centrifugal fan and secondary CFA centrifugal fan while maintaining consistent exhaust volume.
