5048B DC Axial Flow Fan – High-Pressure Cooling Solution for Mission-Critical Electronics

5048B DC Axial Flow Fan – High-Pressure Cooling Solution for Mission-Critical Electronics

In high-density electronic systems, insufficient airflow and unstable cooling often lead to performance degradation and premature failure. The 5048B DC axial flow fan is engineered to deliver powerful airflow, ultra-high static pressure, and extreme environmental reliability, making it ideal for demanding industrial and defense-grade applications.

Engineered for High Pressure & High-Speed Performance

With a compact size of Φ55.2 × 47.7 mm, the 5048B series achieves an exceptional balance between compact structure and outstanding aerodynamic output. Equipped with dual ball bearings and a full aluminum alloy structure, this model ensures long-term stable operation even under continuous high-speed conditions.

This outstanding airflow and pressure performance enables effective heat dissipation in high-resistance airflow paths, such as dense electronic enclosures, sealed cabinets, and compact equipment modules.

Designed for Extreme Environments

The 5048B DC axial fan is developed according to GJB military environmental standards, offering superior resistance to harsh working conditions:

• Wide operating temperature: –40°C to +85°C

• High humidity resistance: 95% RH cyclic testing

• Salt spray resistance: 192 hours

• Vibration resistance: up to 13.5g structural test

• Shock resistance: up to 40g

• Low air pressure adaptability for airborne systems

• EMC compliance: RE102 & CE102

• Power protection: 80V / 50ms abnormal overvoltage tolerance

This makes the 5048B an ideal cooling solution for radar systems, airborne electronics, shipborne equipment, and military-grade electronic platforms.
