Download AFL DC External Rotor Fan Catalogue: Backward, Forward, and Axial Fans for High-Performance Cooling

As a DC fan systems engineer with over 18 years of experience in electronic cooling and industrial ventilation, I know how crucial it is to have clear, accurate data for fan selection. That’s why AFL’s updated DC External Rotor Fan Catalogue is engineered not just for promotion—but to serve as a true technical design tool.

From DC Backward Centrifugal Fans that tackle static pressure in compact enclosures, to DC Axial Fans for directional flow across electronics or HVAC filters—our catalogue contains complete resources to support your thermal management workflow.

What’s Inside the New DC Fan Catalogue?

• Full specifications: voltages (12V/24V/48V), power draw, airflow, noise, and life expectancy

• Performance curves: airflow vs. static pressure for accurate fan duty-point selection

• CAD files: download STEP files and 2D/3D models to fast-track enclosure and PCB integration

• Wiring diagrams and lead configurations: ready for PCB headers, Molex, tinned ends, and custom terminals

• Material details: blade and frame specs (PBT, aluminum, steel), IP ratings, ball/sleeve bearing options

All data validated per ISO 5801 airflow testing and ISO 10302 for sound level reporting.

Fan Series Covered

• DC Backward Centrifugal Fans: for high static pressure, used in filtration, EV systems, and fume extraction

• DC Forward Centrifugal Fans: for low-profile ducted systems and medical or consumer devices

• DC Axial Fans: optimized for directional cooling of heatsinks, enclosures, LED boards, and driver circuits

• All Fans in the DC External Rotor Fan Series: powered by compact, high-torque, external rotor motors for space-sensitive projects

Applications Across Industries

In My Experience – How AFL Fans Solve Real Cooling Problems

We’ve deployed AFL DC Backward Centrifugal Fans in LED driver cabinets across Southeast Asia and EV inverter systems in Germany. The compact design helped reduce enclosure depth by 30%, while maintaining airflow above 200 m³/h at 150 Pa. CAD files and airflow-pressure charts allowed our team to simulate performance in SolidWorks early on—reducing prototype rounds and speeding up certification.

Regional Compliance & Buyer Priorities

• Europe: CE, RoHS compliance, demand for downloadable airflow curves and life test reports

• United States: UL-recognized components, thermally protected models for OEM assemblies

• Asia-Pacific: KC, TISI, SIRIM certifications; urgent timelines supported by AFL's Jiangsu factory
