[APML] Dry Air Purge Rate for hypered film?

[steve banbury <banburys@sonic.net>]

I'm gearing up to use a dry air purge for hypered film, and was
wondering how many cubic feet per minute (or fractions thereof) people
use?

My aquarium tank bubbler is outputting about 0.04 cfm--which doesn't
seem like much, but I recognize the idea is just to maintain a positive
pressure against the moist outside air.
