450-21-0020

The 450-21-0020 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 Capacitor for EBM Multi-Speed Blowers, this unit implements magnetic levitation bearings with >100,000 hours MTBF. The atomic layer deposition coating ensures outgassing compliance with NASA-STD-6012 standards.With a 2.00" (50.8mm) configuration optimized for launch vehicle vibrations, this component survives 40Grms random vibration profiles. The isoelastic mounting system attenuates mechanical shocks by 90% while maintaining thermal contact pressure.
