Key Features

Main Features:

1. DC Brushless Motor: The use of a DC brushless motor is a core feature. Compared to traditional brushed motors, brushless motors offer higher efficiency, longer lifespan, lower noise, and better reliability. They eliminate the need for brush replacement, resulting in lower maintenance costs.
2. Dual Ball Bearings: The design incorporates dual ball bearings, enhancing the blower’s operational stability and service life. Ball bearings have a low friction coefficient, enabling them to withstand higher speeds and loads, but they typically generate relatively more noise.
3. Flame-Retardant Materials: Both the frame and impeller are made of UL94V-0 grade flame-retardant plastic. This is a high-level flame-retardant standard, indicating the material’s excellent fire resistance and high safety.
4. Multiple Models Available: Four models are offered (MG9725H12B, MG9725LH12B, MG9725H24B, MG9725LH24B), corresponding to 12V and 24V voltages and two different speeds (9000RPM and 14000RPM). Users can select the appropriate model based on specific application requirements.
5. Detailed Performance Parameters and Dimension Information: The image provides a detailed performance parameter table, including rated voltage, current, power, airflow, air pressure, and noise, as well as detailed dimension drawings for easy selection and installation.
6. Airflow-Pressure Curve: A P@Q curve graph is provided, visually illustrating the blower’s air pressure performance at different airflow rates, helping users better understand its performance characteristics.

Key Advantages:

1. High Efficiency and Energy Saving: The high efficiency of the DC brushless motor means that greater airflow or air pressure can be generated with the same input power, thus achieving energy savings.
2. Long Lifespan and Low Maintenance: The use of brushless motors and ball bearings significantly extends the blower’s lifespan and reduces maintenance needs and costs.
3. Low Noise (Relatively): Although ball bearings generally produce more noise, the noise of DC brushless motors is still lower compared to traditional brushed motors. Different models have different noise levels, allowing users to choose according to their needs.
4. Good Reliability and Stability: Dual ball bearings and high-quality materials ensure reliable operation of the blower under various working conditions.
5. Flexible Model Selection: Multiple models and performance parameters are available to meet the needs of different applications. For example, applications requiring high airflow can choose the LH model (14000RPM), while applications with high noise requirements can choose the H model (9000RPM).
6. High Safety: UL94V-0 flame-retardant materials enhance product safety and reduce fire risks.

Main application scenarios:

1.Electronic Equipment Cooling: This is the most common application scenario for small blowers.

1. Servers and Network Equipment: Used for heat dissipation in server chassis, switches, routers, and other equipment, ensuring stable operation under high loads. Especially the 14000RPM models, which can provide stronger cooling capacity, are suitable for high-density servers.
2. Industrial Control Equipment: Used for heat dissipation in industrial control equipment such as PLCs, frequency converters, and servo drives, ensuring the stable operation of production lines.
3. Communication Equipment: Used for heat dissipation in communication equipment such as base stations and optical modules, ensuring smooth communication networks.
4. Portable Electronic Devices: Although the 97x25mm size is relatively large, it may also be used in some larger portable devices, such as high-performance laptops and mobile workstations, if cooling requirements are high.
5. LED Lighting Equipment: Used for heat dissipation of high-power LED lamps, extending the service life of LEDs.

2.Home Appliances:

1. Air Purifiers and Humidifiers: Used to drive air circulation and filtration, improving purification and humidification efficiency.
