The purpose of the pneumatic system is to supply compressed air for a controlled temperature and pressure environment during all phases of flight and ground operation.

增压系统的作用是为飞行及地面所有阶段的温度和压力控制提供压缩空气。

Air compressor constant pressure gas supply intelligence control system is by the transducer, pressure sensor, programmable controller (PLC) control unit, software control unit etc.

空气压缩机恒压供气智能控制系统是由变频器、压力传感器、可编程控制器(PLC)控制单元、软件控制单元等组成。

Therefore, optional air compressor is the step: make sure the working pressure, then set corresponding volume flow, and finally the power supply capacity.

因此，选配空压机的步骤是：先确定工作压力，再定相应容积流量，最后是供电容量。

If there was a failure in the air supply system then the pressure would decrease more slowly but still eventually match the outside air pressure.

An ideal one would keep the same rate regardless of variation in power supply, temperature, air pressure, magnetic fields, or any other disturbing influences.
