Sterile air system

The utility model relates to the technical field of food production, in particular to a sterile air system which comprises a sterile air pipeline, a first stop valve, a filter assembly, a first pressure monitoring device, a sterilization filter and a second pressure monitoring device are sequentially arranged on the sterile air pipeline in the air flowing direction. The compressed air source is connected to one end of the sterile air pipeline and is suitable for supplying compressed air to the sterile air pipeline; and the first use target is connected to the other end of the sterile air pipeline. According to the sterile air system, the first pressure monitoring device and the second pressure monitoring device are arranged on the upstream and the downstream of the sterilization filter respectively, and whether the sterilization filter works normally or not can be accurately judged. 本实用新型涉及食品生产技术领域，具体涉及一种无菌空气系统，包括：无菌空气管路，其上沿空气流动的方向依次设有第一截止阀、过滤组件、第一压力监测装置、除菌过滤器、第二压力监测装置；压缩空气气源，连接在所述无菌空气管路的一端，适于为所述无菌空气管路供应压缩空气；
