Application Industries
Servers and Data Storage
AFB fans are used in rack servers, RAID systems, NAS equipment and enterprise storage arrays. Models such as AFB0812HH, AFB0912VH and AFB1212HH are suitable for general chassis ventilation, while thicker 38mm models provide more pressure for dense internal structures.
Network and Telecom Equipment
Network switches, routers and telecom systems require continuous airflow through circuit boards, power modules and restricted ventilation channels. Tachometer versions allow the equipment controller to monitor fan operation.
For 48V telecom systems, models such as AFB1248VHE-F00 can match the available power architecture without requiring an additional 12V fan supply.
Industrial Control
Industrial computers, PLC cabinets, automation controllers and machine-vision systems use AFB fans to remove heat from processors, power supplies and communication modules.
Ball-bearing construction and multiple voltage options make the series suitable for continuously operated industrial equipment.
Power Supplies and Power Electronics
AFB fans can cool AC-DC power supplies, DC converters, rectifiers, inverters and electronic loads. Static pressure becomes important when air must pass through dense heat sinks and magnetic components.
Test and Measurement Equipment
Oscilloscopes, electronic loads, automated test systems and laboratory power equipment require stable cooling while controlling noise and power consumption. Lower-speed AFB models are suitable when extreme airflow is unnecessary.
