D71STA00004G05 is a high-performance aircraft avionics cooling fan, engineered to AS9100D quality standards and RTCA DO-160G environmental specifications, tailored for narrow-body fleets like Boeing 737 MAX and Airbus A320neo. It delivers targeted, low-noise cooling to critical avionics components—including flight management systems, navigation modules, and communication units—preventing overheating during prolonged flight and ground operations.

Constructed from lightweight aerospace-grade aluminum alloy with anti-corrosion coating, it features a brushless motor design (10,000-hour MTBF), variable speed control (1,200–3,500 RPM), and IP65 dust/water resistance. Weighing 0.6kg (120×100×35mm), it integrates seamlessly into avionics bays with quick-lock mounting brackets. Compliant with FAA Part 25/EASA CS-25, it ensures uninterrupted avionics functionality, reduces system failures, and enhances flight operational safety for commercial airline fleets.
