That is a good point. When we refilled the Aerial couplers wth dry nitrogen. The procedure was to run the nitrogen in and let the air out the relief hole. This process was continued for 5 minutes, long enough to purge 99% of the old air out.

5 minutes of this used up enough nitrogen to fill an awful lot of containers.
