8041A DC Axial Flow Fan
Aluminum 80mm High-Speed DC Cooling Fan for Airborne & High-Reliability Applications
When cooling systems operate in extreme vibration, high temperature, and low-pressure environments, traditional plastic-frame fans are often insufficient.
The 8041A DC Axial Flow Fan (78.5 × 78.5 × 40.8 mm) is engineered with a full aluminum alloy frame and impeller, delivering exceptional structural strength, high rotational stability, and superior thermal durability.
With a maximum speed of 22,000 RPM and static pressure up to 783 Pa, this model is ideal for airborne electronics, radar modules, power conversion systems, and high-density thermal assemblies.
