The dried air then passes through left connecting pipe 7 and into filter box 8 for fine filtration. A monitoring device monitors the filtered air quality in real time. If the monitoring results indicate that the filtration does not meet the standards, the third electric valve 15 and the first electric valve 9 are closed, preventing the air from continuing to flow to subsequent equipment.
