I ran the vent/purge air system for 4 hours today, this was the first time the compressor unit was tested since its recent service, service report aLOG 75055.  The results are that the pressure is good, and the dryer system was able to produce a dew point that was measured before the pressure regulator at -45.0 degrees C.  The Kobelco compressor was inspected before and after today's test and no issues or leaks were encountered.
