51172-2-4037

The 51172-2-4037 from ebm-papst Inc. pioneers a new class of Fans - Accessories solutions for aerospace thermal control systems. This radiation-hardened component features gallium nitride power electronics capable of operating in 50krad(Si) environments. Its metamaterial heat sink design provides negative thermal expansion characteristics for satellite thermal balancing.Designed as a zero-maintenance Inlet Nozzle (Wall Ring), this unit implements magnetic levitation bearings with >100,000 hours MTBF. The atomic layer deposition coating ensures outgassing compliance with NASA-STD-6012 standards.Tailored for M4Q Series applications in space-constrained avionics, this adapter features hermetic sealing that maintains <1x10 atm-cc/sec helium leak rates. The non-outgassing adhesives meet ECSS-Q-ST-70-02C qualification requirements.
