351-4000-24GSE is professional aviation ground support equipment complying with AS9100D standards and FAA/EASA regulations, dedicated to aircraft engine maintenance and ground test operations.It serves as a high-precision engine pneumatic test unit, specialized in supplying regulated, clean compressed air for engine pneumatic system checks during MRO. It precisely controls air pressure, flow and purity, matches the pneumatic demands of engine control components, verifies the performance of valves, actuators and sensors, prevents system overpressure or underpressure faults, and ensures the pneumatic control system operates normally before flight or after maintenance.Made of aviation-grade anti-corrosion alloy and high-strength materials, it resists environmental erosion and pressure impact, working stably at -40℃ to 70℃. Weighing 7.2kg, it features standardized quick-connect interfaces, precise pressure regulators and safety relief valves, enabling easy operation and reliable performance. It is critical GSE to guarantee engine pneumatic system test accuracy and maintenance quality.
