Key Features

Main Features:

1. Compact Size: The 75x75x30mm dimensions make it suitable for applications with limited space.
2. Multiple Bearing Options: Offers various bearing types including ball bearings, sleeve bearings, and hydraulic bearings to meet different application requirements for lifespan, noise, and cost. Ball bearings offer the longest lifespan but at a higher cost; sleeve bearings are more cost-effective but have a relatively shorter lifespan; hydraulic bearings fall in between.
3. Flame-Retardant Materials: Both the frame and impeller are made of UL94V-0 grade plastic, providing good flame retardancy and enhancing safety.
4. Multiple Model Options: Provides models with different voltages (12V and 24V) and performance parameters, allowing users to choose according to their actual needs.
5. Detailed Performance Data: Provides detailed performance parameters including voltage, current, power, speed, airflow, air pressure, and noise, as well as a P@Q curve, facilitating performance evaluation and model selection.
6. Meets International Standards: Certified by CE and RoHS, indicating compliance with EU safety and environmental standards.
7. Clear Code Rules: Provides an explanation of the model coding rules, making it easy for users to understand the meaning of different models.

Main Advantages:

1. High Efficiency and Energy Saving: Adopts a DC brushless motor, which has higher efficiency and lower energy consumption compared to traditional brushed motors. Brushless motors reduce friction loss and improve energy conversion efficiency.
2. Long Lifespan and High Reliability: Brushless motors do not have brush wear issues, resulting in a longer service life and higher reliability.
3. Low Noise: Brushless motors generally operate at a lower noise level than brushed motors, which is a significant advantage in noise-sensitive applications.
4. Easy Control: DC brushless motors can be precisely controlled electronically, enabling more flexible speed regulation and control functions.
5. Comprehensive Technical Support: Provides detailed performance parameters, dimension drawings, and coding rules to facilitate user selection and application.

Main application scenarios:

1. Electronic Device Cooling:
2. Small Servers and Network Devices: Used for heat dissipation of server racks, routers, switches, and other equipment to ensure stable operation at a stable temperature. For example, blade servers or small network switches have limited internal space and require compact and efficient cooling solutions.
3. Industrial PCs and Embedded Systems: Used for heat dissipation of industrial control computers, embedded industrial PCs, PLCs, and other equipment to ensure the stable operation of industrial automation control systems.
4. Portable Electronic Devices: Used for heat dissipation of portable electronic products such as laptops, tablets, projectors, VR/AR devices, etc., to reduce the surface temperature of the devices and improve the user experience.
5. LED Lighting Equipment: Used for heat dissipation of high-power LED lamps to extend the service life of LED beads.
6. Communication Equipment: Used for heat dissipation of communication equipment such as wireless base stations and optical fiber transceivers to ensure the stable operation of communication networks.

2.Ventilation and Airflow Delivery in Small Mechanical Equipment:

1. Small Medical Devices: Used for ventilation and airflow delivery in medical devices such as ventilators, oxygen generators, and nebulizers.
2. Household Appliances: Used for air circulation in household appliances such as air purifiers, humidifiers, and dehumidifiers.
3. 3D Printers: Used for model cooling and odor removal during the 3D printing process.
4. Small Analytical Instruments: Used for gas delivery and sample processing in laboratory analytical instruments.
5. Drones/Unmanned Vehicles: Used for heat dissipation of electronic equipment in drones or small unmanned vehicles, as well as some functions that require airflow assistance.
6. Automotive Electronic Equipment: Used for heat dissipation of automotive electronic control units (ECUs), car navigation, and car entertainment systems.
