Key Features and Advantages:

Main Features:

1.  Centrifugal Design: Unlike traditional axial fans, centrifugal fans use an impeller to generate centrifugal force, causing the air to flow radially. This results in higher static pressure, making them more suitable for applications requiring overcoming higher resistance.

2.  Dual Ball Bearings: The use of dual ball bearings reduces friction, provides smoother operation, extends lifespan, and enhances reliability.

3.  High-Quality Materials: Both the frame and blades are made of UL94V-0 fire-resistant plastic, offering good flame retardancy and safety.

4.  Multiple Specifications Available: Offers 10.8V and 14.4V nominal voltage options, along with different speed, airflow, and air pressure parameters, allowing users to choose according to their needs.

Main Advantages:

1.  High Performance: While providing high static pressure, it can also guarantee a certain amount of air volume, meeting various application needs.

2.  High Reliability: The use of dual ball bearings and high-quality materials ensures the fan’s stability and reliability, extending its service life.

3.  Safety: UL94V-0 fire-resistant materials reduce the risk of fire and improve safety.

4.  Complete Certification: It has passed CUS, CE, ROHS and other certifications, complying with international safety and environmental protection standards.
