It looks like right before the lower airflow 1 reading, the buffer tank pressure did not reach the same upper pressure and also went to a lower pressure than usual. This is in the red box in the attachment. The drop in air flow is probably due to the system
trying to catch up and get back to the normal operating pressure.<br>

increasing.<br>
This could be potentially dangerous, if the temperature keeps going up <br>
we could reach the interlock limit.<br>
