The constant maintenance of FE's inflatable membrane's appearance and shape is primarily determined by its inflation system.

The inflation system is a crucial component of the ETFE inflatable membrane structure system, serving as the primary power source to maintain system operation, preserve the appearance and structural integrity of the air cushions, and ensure their load-bearing capacity. The inflation system primarily consists of inflation units, inflation pipes and valves, and electronic monitoring systems. Among these, the inflation unit is the core of the entire system, providing all air cushions with pressurized, dry, and clean air. The supply system, comprising inflation pumps, control units, and intake and exhaust ports, can maintain the stability of the membrane structure buildings and allows for real-time monitoring of the equipment directly on a smartphone.
