Key Features and Advantages:
Main Features:
1. Size and Type: A standard 120x120x38mm AC brushless fan, classified as B-type. This is a common standard size in industrial and electronic equipment, facilitating compatibility and replacement.
2. Bearing Type: Employs a ball bearing design. This is one of its crucial mechanical characteristics.
3. Material: Both the frame and impeller are made of aluminum alloy, with a flame retardancy rating of UL94V-0.
4. Diverse Performance Parameters: Offers both 110VAC and 220VAC voltage specifications. Under different voltages, it maintains similar rotational speeds (2750/3200 RPM), airflow (105/123 CFM), and static pressure (7.1/8.9 mmH2O).
5. Certifications: Possesses multiple international certifications, including UL, CE, and RoHS, indicating compliance with relevant safety, health, and environmental standards.
6. P&Q Curve: Provides a pressure-quantity (P-Q) curve graph, visually demonstrating its performance under different loads.
7. Weight: Each fan weighs 535g, which is relatively heavy, likely due to the all-aluminum alloy construction.
8. Noise Level: The noise range is between 47-49 DB-A.
Main Advantages:
1. Long Lifespan and Reliability: The use of ball bearings is one of its most significant advantages. Compared to sleeve bearings, ball bearings offer a longer service life, better high-temperature resistance, and higher reliability, especially suitable for equipment requiring continuous long-term operation.
2. Excellent Heat Dissipation and Durability: The all-aluminum alloy (frame and impeller) construction ensures the fan’s structural rigidity and resistance to deformation. Aluminum alloy itself has excellent thermal conductivity, which helps dissipate heat from the fan itself, further enhancing its stability and lifespan. The UL94V-0 flame retardancy rating also adds to the product’s safety.
3. Broad Applicability:
o Its standard size makes it easy to integrate into various equipment and chassis.
o The availability of both 110V and 220V voltage specifications allows it to adapt to different power standards worldwide, greatly expanding its range of applications.
4. Stable Performance: As seen from the specification table, despite different voltages, the fan maintains consistent performance in key indicators such as rotational speed, airflow, and static pressure. This indicates that its design provides stable cooling performance across different power environments.
5. International Certification Assurance: Having UL, CE, and RoHS certifications means the product meets international market access requirements, guaranteeing quality and giving users more confidence in purchasing and use. This is particularly important for export and international projects.
6. Good Airflow and Static Pressure Performance: An airflow of 105-123 CFM and static pressure of 7.1-8.9 mmH2O for a 120x120x38mm fan provide good air movement and the ability to overcome resistance, effectively meeting the cooling needs of most equipment.
