archived data for airflow drop on compressor power off - For reference, attached is archived data showing the RICH buffer tank air pressure, airflows, and low airflow interlock limits.

Approximate time from when the compressor was turned off to...
Airflow 1 Low interlock trip: 2 minutes
Airflow 2 Low interlock trip: 3.5 minutes
Both airflow measurements reached ~ 0 slm: 6.5 minutes
